Ex Amazon here. Most grumpy system engineers did not disappear: we got hired by Google/Amazon/etc to build large-scale infrastructure... and sometimes sell it back to you as a service.

Believe me or not, most of the underlying infra does not run on the popular technology of the year. Far, far from it. That's why it works.

Modern devops, with its million tools that break backward compatibility every month sometimes becomes the running joke at lunch.

seorphates 92 days ago [-]
Grumpykins here. I think the term "Modern devops" sort of nails it but not quite how you used it. Most departmental/enterprise sys admins/engineers of lore that had even the slightest necessity for life outside the box scaled anything resembling automation to its breaking points. Combined with knowing and serving the reasons for their existence - developers, users etc., and devops is nothing new - it is now simply the necessary manifestation of progress at scale (albeit positively devoured by managers speaking business, not entirely unlike "agile").

"Use what works" definitely presents a lot more choices these days and likely will forever more.

"Use what works well" is something different where "well" implies helpful, dependable, predictable, manageable and so on that will continue to scale with your needs. Only breaking things down the "old-school" way will lead towards success, stability, security and life outside the box.

Good devops is still, primarily, good engineers engineering good things, for themselves and others.

Granted the article is from 2015 but my impression is author is not just cranky, but scared.

Agreed. DevOps has been a thing for a long time. The funny thing is that the core of the DevOps philosophy —- to unite development and ops through code —- is still a rarity. SO MANY big companies have entire departments for DevOps that are basically either developers doing release management sysadmins writing pseudo code for infrastructure while making it somehow less accessible to development teams.
hennsen 92 days ago [-]
DevOps is uniting dev and ops through code? I believe it’s at first and most important to unite them through good(early, often, honest, etc.) communication and collaboration instead of “you broke x” and “you have to fix y” as well as “this is the other (dev or ops depending who says it) departments fault/task is the most important thing in DevOps. The code is just a tool to make this collaboration easier / automate it where the other things already happened and all understood they work on the same goal and not as enemies.

A good sysadmin would not look like they are doing much work (everything is humming along and can self-heal minus physical problems), but a good devops person is constantly busy.

I sort of agree but a good sysadmin was never idle on the inside. I'm seeing good devops people getting worked well beyond what I'd consider reasonable expectations i.e. "Oh, look, you can do everything! Here's everything!".

They're being perverted into a role having a full load of pure operations with shit for processes (and, often, systems) and an expectation that you have time to automate and shore up all the shit and technical debt accumulated since.

Can most good or even extraordinary developers simultaneously be elbow deep on a dozen unrelated products and actually get reasonable traction? I can barely keep one glass castle together, myself.

This is exactly my sentiment and why I moved away from SRE and back to SWE. I felt busy all the time doing development of tools and infrastructure while at the same time aggregating the role of operations.

Never having the time to properly finish a project that I was proud of delivering, turning those into services so we could leverage self-servicing was a dream that most of the time never happened, we were left with half-done systems requiring tons of manual intervention (lots of toil) while having to move fast to the next thing...

Twirrim 92 days ago [-]
There's rarely anything old school sysadmins have learned that hasn't come from experience.

Been there, done that, fought that shit the first time. And the second. And the third. (it's amazing how often I find myself solving what are essentially the same problems over and over.) It's one reason why you'll find we'll push back on the "ohh shiny". There are many wonderful and fascinating things coming out. Tech is an amazing field to be working in. But it's also ridiculously frustrating because no one pays any attention to _why_ things are done the way they are, or _why_ approaches haven't worked in the past (I'm all for re-introducing past failed approaches, as long as there's evidence those reasons have been investigated)

You'll find a common trend amongst us in that most of us sort of ended up in the role accidentally. Schools and college teach you to become developers. Few people tend to head to college with the view of specialising in the ops side of things.

Even speaking as a comparatively old-school sysadmin, my strengths come from being flexible and adaptable. What I do today is nothing like what I was doing 5 years ago, and what I did then is nothing like what I was doing 5 years before that, and so on down the line. The field is constantly in flux.

I just have the best part of two decades of experience to both anticipate the problems, and be able to get to diagnosis quicker when things do go wrong.

Even as the older sysadmins die off I'm fairly confident there will be newer ones to replace them, because people are going to continue to learn from the problems they run in to.

ams6110 92 days ago [-]
Ansible is one "ohh shiny" thing that has greatly increased my productivity as a sysadmin. Before that I would automate what I could with ssh and pdsh and scripts, but it was never as well polished as Ansible.

I'm even using ansible for ad-hoc stuff (tweaking a config, restarting a service) because it's easier to do that from a management server than log in to some remote host, get oriented as to the OS distribution and version, and run commends in the shell there.

noir_lord 92 days ago [-]
I like ansible with vagrant as well - it makes for a nice clean way of deploying to development environments while also been nicely 'self' documenting and not limiting (you can drop back to shell), it's a lovely tool for the most part.

Edit: The thing I really like about Ansible is how unsexy it is, it's just a nice sane way of doing largely what you could do yourself with ssh and bash but in a language that doesn't make you want to cry.

I've been around linux since the 90's and Ansible feels comfortable, predictable and stable - what you would want in a piece of software that can be mission critical in the most fundamental sense.

dozzie 92 days ago [-]
It would be even nicer if people weren't advocating it as a configuration management system, only as what it is: a deployment system.
piva00 92 days ago [-]
I think I achieved my perfect balance of tooling for current systems with Ansible and Docker.

Ansible automates even provisioning in AWS. I never really liked CloudFormation's way of creating stacks, so I began to use Ansible to document the application's stack, have used it to deploy systems running in EC2 with RDS, ElastiCache, SQS, SNS, DynamoDB, etc.

After provisioning/configuring I'd end up with an instance in EC2 with Docker installed and from there our CI/CD would just trigger the deployment playbook that simply would do a `docker pull` of the version tagged for release and start the container.

Ansible helped to also install our Splunk forwarders as running it from Docker was a hassle still not so long ago, so we would have the best of both worlds: configurability of the host machine completely with Ansible and packaging and predictability of deployment through Docker.

I advocate this stack as simple enough to learn and use with widely used tools without their fancy (and often broken) features. Even though they can be still a bit immature, they are production-ready enough.

I used puppet -- unhappily -- for a while before discovering SaltStack.

Salt, like Ansible, is a response to the Puppet/Chef hegemony -- ruby and DSL's and tacked-together bits that are a nightmare to install and upgrade in themselves).

I'd suggest Salt did some things much cleaner than Ansible, and while it can be an orchestrator, and deployment system, it also excels as a configuration management system ... but I think typically people are talking about configuration management systems that are tightly coupled with more formal change management systems (of which I've found pretty much none that work well).

I don't know how the situation is in the US, but in my country network engineering is actually quite a popular field of study. (we have college level education in network engineering).

The one thing that stands out though is that it's mostly done by youngsters who have either sysadmin experience, or worked in IT before that. Almost everyone who comes from high school goes into Software Engineering.

I think this is mainly because networking is quite an invisible field so to speak. Many people don't even know your job exists, and many young people only see the shiny hip side of it. (being Software Engineering).

Being good at network engineering is hard, especially once you get past entry level work and actually start being responsible for designing large-scale networks. Mainly because building a network is a major financial investment where garuanteeing performance is hard without either a ton of experience, or a shitton of lab time.

this kind of work pays very, very well though.

Building networks and understanding protocols is something machines can do TODAY. The entire internet was built to survive a nuclear war. It can reshape itself, and it most definitely understand network protocols. By definition, protocols are the language of machines over the network. And it's been like this for a few decades.

The first attempt at a system to turn plain English that even managers could write into executable code was 1959 - COBOL.

The Internet really cannot "reshape itself" and probably never will be able to.

RIP and OSPF are interior routing protocols---that is, they're used for routing within an organization (or autonomous system in Internet lingo) and deal with technical routing issues (fastest link, most bandwidth, etc). BGP is for routing between organizations and deals with political issues than technical issues (we need to send all traffic here due to contracts, unless it goes down, then shift traffic over there; and refuse routing information from such-n-such organization because they don't have their act together).

CFEngine is basic text manipulation, it's not comparable to the rest.

Puppet and Chef was the first generation. I wouldn't recommend. All the companies and people I know using Chef migrated away from it after many disasters. Nowadays, it's only mentioned in interviews to find out if candidates have real world fire fighting experiences.

Ansible is good. Used that for managing hundreds of machines at multiple jobs (some who migrated from Chef). It's been bought by RedHat, it's well maintained and I think it will have the brightest long term future.

Not sure about SaltStack. Never had the opportunity to try. I'd be a bit worried though on the long term prospect because I don't think they have much backing or user base.

saltstack is a well thoughout solution in my opinion. It makes more logical sense and is less of a mumbled mess then either chef or puppet and has miles better performance then ansible.

I know quite a few shops who use it. Its definitly smaller then ansible.

mattbillenstein 92 days ago [-]
+1 for salt -- I wish it had better docs or examples of how to build out a larger system; it's hard to start with imho even if you know ansible well. The existing docs read like man pages without the helpful examples even.

At the last gig, I wrapped salt deploys with a small Slack bot, so users would fire deploys from Slack; you could see what was going out and who was pushing. It was a very very nice, simple, fast solution that should scale to hundreds of machines easily.

kokey 92 days ago [-]
CFengine, at least version 3, was probably the furthest away from string manipulation (and I was given the impression that text file content manipulation was considered a bad idea with it). What killed it was promise theory, which is actually a great theory and works quite well but made writing the bundles painfully hard and also hard to maintain. Also during the early days of v3 it was probably lacking a ton of essential functions so even if you were trying to do things the right way you would bump into feature limitations. I think this put a lot of people off adopting it widely and why Chef and Puppet did so well.

Puppet and Chef is actually quite good and I still prefer it to Ansible for a number of reasons. I've certainly run it fine in environments of many thousands of servers, though I can understand that it can implode for some people at scale if they design their deployments in a certain way or structure their manifests/cookbooks a certain way. That said I've certainly seen Ansible fold on much smaller infrastructure, but that is also down to a number of factors that can be avoided or mitigated. Idempotency with Puppet is really strong which is something you want if not every single system in your environment is ephemeral, with Chef it's almost as good with that but not always with the first run, with Ansible you have to specifically consider and aim for it when writing code for it in your playbooks.

The fact that you get used to having Chef or Puppet run e.g. every half an hour is a good thing, where Ansible runs are more ad-hoc. This leads me to another thing that bothers me and that is where people think it's a situation of having to use e.g. Puppet or Ansible as if they're conflicting choices for the same tasks. They have a lot of things in common, but Puppet is more for managing and ensuring changes in an idempotent, non-conflicting way while Ansible is more for doing something a bit like that but more for ad-hoc or orchestration tasks. I think it's good to use both but also be sure what you use it for, since one can do a bit of what the other thing is good at but doesn't do it so well.

For example, I would consider using Ansible to do deployments and releases, rotate SSH keys, execute failovers, or even to install the Puppet agent for the first time. I would use Puppet to deploy and update monitoring agents and configuration, user access, ensure directory permissions, configure system things like rsyslog, logrotate, Postfix, ntp, etc.

dozzie 92 days ago [-]
> This leads me to another thing that bothers me and that is where people think it's a situation of having to use e.g. Puppet or Ansible as if they're conflicting choices for the same tasks.

That's mainly because Ansible folks advertise it as a configuration management tool, while in fact it's a deployment tool. The former needs asynchronous operations, especially because a node that is supposed to be reconfigured can be temporarily down. The latter needs to be executed synchronously, with reports being read as they come by an operator.

There are several other operation modes that are useful for a sysadmin, like running a predefined procedure with parameters supplied from the client, or running a one-off command everywhere (even on the servers that are currently down, as soon as they are up), but we don't have many tools to cover those cases.

Ansible has a very, very low barrier to entry. You go from 0 to 100 in a very short time. It makes a lot of sense to use it when you just begin building your infrastructure.

Later on you can run Ansible Tower, deploy Ansible agents everywhere, and basically use Ansible under the same client/server model like all the other tools.

There's nothing stopping you from having a sshd instance dedicated for use just by ansible, on a different port/different network, on every node. Now if that's simpler or more complex I don't know.

But "have two ways in" is a basic principle of sys admin (typically via traditional network and some out of band console access).

twic 92 days ago [-]
When i worked with physical machines, they had embedded management systems, which were on a physically separate network to the machines' main interfaces, ran a little embedded SSH server, and would (amongst other things) give you a console on the machine.

Simpler machines should still have serial consoles, and you can get those on the network via a terminal concentrator or a serial-to-ethernet adaptor.

I would love it if Ansible could control machines over an interface like that, rather than via SSH. Then you wouldn't even need to run SSH on machines which don't need it, which is most of them.

Wrong. Teach your sysadmin not to overload a single service with different functions (debugging channel, user-facing shell service, running remote commands, file upload, and config distribution channel), especially not the one that should not be used in batch mode, without human supervision.

When you write an application, you don't put a HTTP server in database connection handling code, but when it comes to server management, suddenly the very same approach is deemed brilliant, because you don't run an agent (which is false, because you do, it's just not a dedicated agent).

voltagex_ 92 days ago [-]
Are you advocating running multiple sshd instances in this case?
dozzie 91 days ago [-]
Good heavens, no! You'd only have two different instances of the same service that is difficult to work correctly with.

For serving as a debugging channel and user-facing shell access, SSH is fine (though I've never seen it managed properly in the presence of nodes being installed and reinstalled all the time). But for everything else (unattended):

* you don't want commands execution, port forwarding, or VPN in your file server

* you don't want remote shell in your daemon that runs parametrized procedures -- but you do want it not to break on quoting the arguments and call results (try passing shell wildcards through SSH)

* you don't want port forwarding and remote shell in config distribution channel; in fact, you want config distribution channel itself to be reconfigured as little as possible, so it should be a totally separate thing that has no other purpose whatsoever

* you don't want to maintain a human-user-like account ($HOME, shell, etc.) for any of the above, since they likely will never see a proper account on the server side; you want each of the services to have a dedicated UID in /etc/passwd, own configuration in /etc/$service, own data directory, and that's it

Each of the tasks above has a daemon that is much better at them than SSH. The only redeeming quality of SSH is that it's there already, but it becomes irrelevant when the server's expected life time gets longer than a few days.

I'd venture to say you're wrong about Salt. It's being used at some large enterprises. I use it (in one of the large tech companies) on thousands of servers, with plans to up that an order of magnitude or more. Of all of the solutions mentioned, it has been the most powerful, while also being the most scalable.

Other than that, my experiences line up with yours almost exactly.

I love SaltStack, its more of a python framework for managing systems over ZeroMQ than it is pure configuration management. Compared to Ansible it's more complex but faster, reactive, and significantly more flexible. I'd highly recommend it over Ansible for larger environments. For smaller ones, it depends on if the steeper learning curve is worth it.

+1 for Ansible from me.

Of all the tools, I first heard of Puppet first and so I'm assuming it was first on scene? From my limited experience, it seems Puppet is most widely used tool because of that reason. Not necessarily the best of the bunch, but first on the scene. Considering the effort required to roll it out, I am assuming whatever is deployed first will stay as the tool of choice.

I've tried out Puppet, SaltStack, and Ansible, in that order.

What I didn't like about Puppet is that once you deploy a change, the actual change can happen on the "client servers" at any point within next 20 minutes. I may be off on the exact duration but I remember that changes were deployed at any point within that range of time. To me that sounds like not a great idea. What if you want to switch over your web servers at a specific moment? And Puppet requires a dedicated command/control server.

Next I tried SaltStack. I liked it enough. Now that I think about it and hear someone else mention it, yah SaltStack is similar to Ansible. What drove me away from SaltStack was that you essentially need a dedicated command/control server from where all SaltStack commands are sent out to SaltStack "client servers". I did not want to dedicate resource (and money) for a server that is rarely used. And the personal web/lab servers I manage can grow small/large from 2 servers to 10 servers.

Next I tried Ansible. I think Ansible is the perfect choice for me. I only needed to 'devop' just a handful servers and also learn a tool that many businesses seemed to want on resume. So I picked Ansible and it's been great. Some operations are not as flexible as doing it with a shell script (and I assume same issue exists for other tools). But I've had good luck combining Ansible with little bits of shell script to get the result I need.

The best part of Ansible is that any Mac or Linux machine can be used as the "command server", provided that you have the SSH key pair on your Mac or Linux machine.

Lastly, some may not like the ad-hoc way of doing things on Ansible, but I prefer it that way.

I first heard of Puppet first and so I'm assuming it was first on scene?

CFEngine was first, it's based on a kind of maths called "promise theory" and it solved the problem of you had many different kinds of Unix owned by many different groups and had to have a consistent way of saying "all machines belonging to group X need to have user Y and package Z" and it would abstract away the slightly differing syntax between Solaris, SunOS, IRIX, OSF/1, Ultrix, yadda yadda. This is a problem that doesn't really exist anymore.

Chef I think came next, it was written by people who knew Ruby but didn't know maths so they used CFEngine terminology like "converging" but Chef doesn't really do that, it just runs Ruby scripts. If CFEngine was a scalpel, Chef is a mallet. Chef and Puppet are related somehow, same group of devs had a falling out and went their own ways, something like that. They are much of a muchness.

Ansible is cool because it recognises the reality of why CFEngine isn't relevant nowadays: most organisations are running just one particular Linux distro so you can do away with the abstraction and get all the benefits without the complexity.

> it's based on a kind of maths called "promise theory"

Promise theory is not math, despite its name. It doesn't predict anything, it doesn't explain any phenomena. It's an architectural approach. Brilliant, led to a really great software (CFEngine), but it's not "maths".

Basic concepts of promise theory (10 minute video by Mark Burgess who came up with it): https://www.youtube.com/watch?v=2TPsB5WuZgk

2014 introductory article: https://www.linuxjournal.com/content/promise-theory—what-it

Basic book on the subject: https://www.amazon.com/Thinking-Promises-Designing-Systems-C...

It's not "maths" like arithmentic but it's "maths" like graph theory:

Promise Theory, in the context of information science, is a model of voluntary cooperation between individual, autonomous actors or agents who publish their intentions to one another in the form of promises. It is a form of labelled graph theory, describing discrete networks of agents joined by the unilateral promises they make.

> It's not "maths" like arithmentic but it's "maths" like graph theory

It's less like graph theory and more like inversion of control: an architecture, not a set of theorems and their proofs. Even Burgess' own book you mentioned is nothing like a mathematical handbook.

I'm a great fan of Mark Burgess and his promise theory, but calling it a mathematical theory or a mathematical domain is simply incorrect.

The book I mentioned (Thinking in Promises) is the introductory-level public book.

You don't. Configuration management is a wrong operation mode for a synchronous change. Still, you could order all your Puppet agents to run their scheduled operation now instead of leaving it waiting for its time.

nunez 92 days ago [-]
Ansible all of the way. Chef and Puppet have too much overhead in comparison. Ansible is agentless. You can either use a centralized server for deployments or you can have every instance configure itself. Also, Ansible is YAML based, which is a strength and a weakness.

Chef is a runner up. Love their community and Chef is pretty straightforward once you learn the lingo.

Puppet doesn’t really work for modern Git development workflows (Hiera and r10k are duct tape) and testing Puppet is kludgey. Also, most of the docs you’ll find for it stopped getting updated in 2015 or so.

busterarm 92 days ago [-]
I've used chef, ansible and saltstack in small startup and large scale enterprise environments.

Ansible is just about the easiest and most flexible thing going, but once you hit "very large scale" you're going to get bit by its performance and start worrying about when you actually update things. Ansible Tower starts to look good then, but it's not the well-walked path and brings you all sorts of other issues about how you distribute secrets to bootstrap things.

Chef is kind of nice when you don't have a lot of environments that you need to manage and about as flexible as you need it to be in those situations.

SaltStack shines when you really have a lot of heavy lifting to do and the Event System, Beacons and Reactors will honestly blow your mind with the complex things you can achieve in a way that's simple to reason about and maintain.

That said, there's really like 3-4 majorly different ways you can (or would want to) use Salt and understanding it and its documentation is a large cognitive investment. You will likely run into major pain at some point down the road if you choose to use it. I would only use it again if I had a really good reason to -- pretty much if there's no other alternative. I would not at all bother using it to try and do typical sysadmin automation tasks.

Strange side-note: The best managed Salt environments I've worked in or looked at were all masterless, whether at small or massive scale. It's my probably-wrong opinion that traditional master/minion SaltStack is always going to cause you enormous problems eventually when you need to either scale out or pivot on something.

The clearest explanation of why this happens is at the end:

Before, admins would try hard to prevent security holes, now they call themselves “devops” and happily introduce them to the network themselves!

1) The merging of devs into the sysadmin role was a product of: the work of sysadmins (particularly systems change control and security compliance) not being valued in our culture.

2) Devs delighted to be free of the shackles placed upon them by sysadmins who were encumbered by the concerns expressed in this article.

If you were a devop who resolved to fix the problems bemoaned in this article, my guess is you would turn around in 60 days to discover you'd become a sysadmin.

agentultra 92 days ago [-]
I recall the idea of "devops" from this book: https://landing.google.com/sre/book.html

The stated goal of putting both systems administrators and software engineers on the same team is to reduce friction and increase communication. One of the worst, productivity-killing situations you can find yourself in when developing network software and services is caused by the traditional "old school" mentality of separating the two camps. When your software developers operate independently of your systems engineers and administrators they're forced to make assumptions about infrastructure, operations, and compliance goals. Both teams have the same goals so why are they not on the same team? I think some "old school" system administrators don't realize how costly such communication mistakes are. Getting 6 months into a development project to be told you cannot have a critical piece of infrastructure _for reasons_ is a costly, costly mistake.

Containers are a smart solution to the build problem. Don't build your containers from public, un-trusted images! Build your own images. Run your own, protected, registry. You still have all of the compliance and validation necessary and you don't end up debugging failed builds because one machine out of a thousand is running on some minor shared library version not supported by your software.

drbawb 92 days ago [-]
>Don't build your containers from public, un-trusted images!

The author is complaining that you can't build these private trusted images. Software developers have got it in their head that containers are a way to package & distribute software. They're not, that's what the OS's package managers are for. If your software requires Docker as a build dependency, you have failed to properly package your software.

As a concrete example look at Ubiquiti's UNMS.[1] Their package consists of downloading & installing Docker binaries on your system, not tracked by the OS package manager, and then running a bunch of containers built from these public un-trusted images you just told me not to use.

They also conveniently ignore the fact that I already have a Redis server, I already have a PostgreSQL server, I already have an NGinx proxy. (Plus I guarantee my database servers are better tuned for my hardware than some random image from Docker's library.) It is not up to some random software developer where I should be drawing the isolation boundaries on my infrastructure. They also make the big assumption I want to use Docker to manage my containers in the first place. Perhaps my company already uses Solaris LX-branded zones, or LXC, etc.

Now imagine if instead of spinning up a PostgreSQL database container, it used MS SQL as it's database of choice. You think I'm going to let some random developer dictate whether or not I should spin up another SQL Server instance and pay MS for another round of cores / CALs?

Yes - you can build your own containers, and they're fantastic - if software developers properly package that software for ease of installation & configuration. Software developers should not be dictating what container/virtualization framework I use, what configuration management I use, etc.

There are public trusted images, like the so-called official repositories on Docker Hub [1]. As long as you build your images based on official repo images, you're probably fine. Just don't depend on untrusted images; instead get their dockerfile/config files, and build the images yourself.

To me, a Docker image seems like an ideal way to distribute some proprietary device management web software like Ubiquity UNMS, rather than requiring some obscure version of some database or whatever other dependency actually be installed and maintained by their clients. You can spin that image up on a server or group of servers, or on Amazon ECS or a bunch of other providers in a matter of minutes. With enough motivation, you could even export the image and manage the environment manually.

Why would you want to do that though? Treat the whole thing as a black box running inside docker and be done with it. The second you crack it open, you get to support it. Let Ubiquiti support it, after all that's what you are paying them the big bucks for.

15155 92 days ago [-]
Ubiquiti has always done this, even before containers were "hot."

If you install their rpms or debs for any of their properties, you're almost always getting a copy of Mongo or some other dependent service... and it is probably going to be incompatible with whatever version your package manager has or you're already running (version-constraints-wise, not actual compatibility-wise).

This is an indictment of Ubiquiti, not containers in general. If their software were properly built, they'd be shipping you a docker compose setup or something with N different containers that you could substitute out (at a network level) for your own.

I once worked at a company which separated IT into 3 teams: developers, DB-sysadmin (ops), and QA (who also managed deployments). Releases were supposed to go in a waterfall model from the Dev group -> QA group -> Ops. QA wanted Dev to submit Word documents for each release with blanks to be filled in with server names. However Ops was so distrustful of Dev that it was not enough for them to lock us out of Prod using regular security tools, we were also not allowed to know the NAMES of servers in Prod or how currently deployed systems were grouped.

Every release was an Abbott-and-Costello "Who's on first?" routine. Do you have any idea how hard it is (especially in computing) to ask for something without being able to utter its name?

QA: "You left servername blank on this deployment document."

Dev: "I know; Ops won't tell me. Just ask them for where the service is currently."

QA: "Ops says there's 5 unrelated legacy services with that same project name, on different servers."

Dev: "5? I only knew about 3. You know, if I could query the schemas of the Prod DB, I could tell you in a jiffy which one it is."

Ops: "Pound sand. If you want look at databases that's what the dev DB server is for."

Dev: "Erm, OK well can I give you a listing of the Dev DB schema and you tell me if it looks like the one the Prod service is talking to?"

Ops: "Oh I see you want us to do your job for you now? You can compare the schemas."

Dev: "OK..."

Ops: "Just tell us which DB server you want the schema pulled for."

Dev: "But you won't tell me the server names."

Ops: "No."

My point is this is how bad communication can be when ops and dev are not on the same team.

Devs hardcoding things in their software in a rush making the software tougher to deploy and operate causing greater incident rates and therefore page-outs. Devs interested in greater resilience and stability in their software should be opting for dependency injection of pretty much every damn thing in the world around them whether it’s a network service or file system location. Otherwise, presume that it can go away at any time. A common pattern among developers trying to save time that costs more in the long run is to hardcode a path to an executable. A simple /use/local/bin/ buried in an infrequent job that is installed on developer machines but never in prod is all it would take to cause an incident in prod that costs the company millions. I say this both as someone that has written this and had to fix others committing the same error in their code and QA passing it along.

Ops tends to be where the brunt of technical debt is truly buried. Bad code is one thing but seeing the code in action with real world data is a different beast altogether.

The thing is that any separation in the roles in ineffective. Things shift around some if you embed an ops guy into the dev team directly, but it doesn't resolve the core problem. This applies to DBAs as well as ops or any other software-side segmentation as well.

The core problem is that there are "ops guys" and "dev guys". That creates conflicting incentives, even within the same team. It creates tension and a dynamic centered around bandying work around so that it's "the other guy's problem" in some situations, and hoarding logic onto the one segment so that there isn't an "obstruction" in getting things done in others. Moving the "segmented" guys directly into your team just makes these politics closer to the heart, which is not always an improvement.

Teams should be comprised of whole-platform "generalists" (in quotes because they really should be good at stuff, whereas "generalist" implies they aren't; here I just mean a competent non-specialist), where any single individual would be comfortable/capable performing any particular task that may come up. Of course, each member will have preferences and habits, little "skews", but it is important that these skews are controlled and used for mutual education, and not allowed to "flandersize" someone from "the guy who knows SQL better than the rest of us" to "full-fledged DBA who hasn't committed any C# for 3 years".

The right axis for separation is hardware v. software. If it's software-related, your dudes should be equally yoked, such that any SQL ticket would be assigned to any member of the team, or any "devops"/sysadmin/deployment ticket assigned to any member of the team.

These systems, from the OS up, are all part of the same thing, and they're all tightly integrated. Making the workload of the individual people on the team also tightly integrated is the only way to make sure that incentives align properly and that the most effective technical decisions are made, instead of decisions motivated, consciously or not, by offloading blame or other political/effort/convenience considerations that cause the overall system to suffer.

If you get into a sticky situation that requires specialized help from someone who has lived and breathed MySQL Server night and day, well, that's what consultants are for. Consultants would also be useful for inspections/sign-offs. But your core team can't tolerate being segmented out by component/implementation detail.

> Containers are a smart solution to the build problem.

Linux "containers" are a variety of things. True OS "containers" don't exist on Linux, but there are some rudimentary approximations. A Docker image is essentially a zip file, and sure, zip file-ish things may work fine for uploading artifacts to systems. Dockerfiles are unequivocally terrible, however.

I agree with parent, but I think you're taking it too far. I don't think there are enough skilled generalists to pull off your ideal, and I think software/infrastructure is too complex to allow for generalists in the breadth you describe.

I'm a security person who knows pretty good Python and simple database stuff (SQLite). I think I'm in the top 50% (humbly) of my field, probably higher.

But I don't know front-end, containers/CICD, or disrtibuted systems worth a damn.

I do believe parent, which is the idea that teams should have embedded resources. A "VM security team" operating firewalls and infrastructure and policy auditing should not only have security experts, but their own devops group that automates the crap out of everything, using 2018 best practices. Currently, my team's "dev" group is a separate team in another area whose work queue is fed by multiple, distinct teams. It makes learning and understanding our requirements really tough for them.

You're right that everyone is not going to start out knowing everything. No matter how senior you get, there will always be areas you know better or areas that you prefer, which are the "skews" I referred to in my original comment. When a new framework or technology or whatever is introduced, only one or two people will know it. That's all fine.

Docker is the epitome of the broken segmented model. Devs hate and resent ops telling them they can't do things. Docker promised devs that if you spend a half-hour writing instructions to build an archive that contains your app's file tree and to pull in a completely untrusted OS userland `nice-mans-alpine:4.x.malware-free`, those annoying ops people will get out of your hair, and you can go ahead pulling `bad-actors-handy-4line-totally-safe-lib` from npm to your heart's content. No more complaints about that package not being approved, or the dependencies not installed, or the runtime too slow, ha!

The whole comment thread on the original article is a case in point. Someone who is responsible for the whole software side of real systems will be horrified at the suggestion of such recklessness. However, developers who're only accountable for pushing "at least one commit per day!", and consider security and performance someone else's problem, will be thrilled at the prospect of "tearing it up with some 10x coding" while they silence "the Luddites". (who, sidebar, were too dumb to see the beauty in JavaScript back in the 90s! Pshaw!)

Which dynamic do you want to encourage?

> And what are junior developers supposed to do?

The same thing that everyone else is supposed to do: learn it, gradually, as needed. Read the docs. Seek mentorship from team members who have that "skew" (formalize this process if necessary). Read the changelogs. Read the code. Figure it out!

Many will protest and say it's outside of their comfort zone. Some will protest and say this is inefficient. That may be true in the short-term, but the system will invariably suffer if you do hard segmentation on the software work, because the falsely-separated concerns won't understand each other and end up setting up territories.

People will hate the DBA because they won't understand why he cares about "boring crap" like "normal form". People will hate the sysadmin because they won't understand why he cares about "boring crap" like "not being woken up at 3am". Your front-enders will be more gregarious and have better haircuts, leading to prioritization of front-end concerns.

Essentially, the project becomes driven by blame-shifting, protectionism, and which software-side segment has the more attractive people, because the concerns are fungible enough that any side could potentially handle them. That makes it a political competition. The project is no longer driven by technical prudence or efficiency. It's no longer about the tradeoffs involved in solving the problem at layer X instead of layer Y.

The dividing lines from OS up are arbitrary. We can't all be experts in all of it, but we can all have the expectation that we need a basic grasp over the whole system, by which I mean the WHOLE SYSTEM, and that we should become competent in the major elements used to build it, and patiently nurse this competence over time.

One team member should be able to handle 90% of the tickets that come in independently, whatever elements of the stack are affected (sysadmin, application code, database, frontend, etc.), and when they hit one of the 10% they can't do independently, they should consider it their responsibility to seek mentorship and learn the skills so that after several such rounds, they can do it independently.

The only real question is whether there are enough people capable of this out there. I think there would be if we set it up as a general expectation. I'm not sure if there are when we've already accepted the segmentation as a fact of life.

cookiecaper 92 days ago [-]
Once the downvotes start coming in, people read comments uncharitably, and the thread gets lost, but to be clear, I'm not advocating for anything that is beyond the cognitive capacity of typical software developers.

One and two-man startups provide ample evidence that working knowledge of the whole platform is not beyond human cognitive scope, even if getting this to be accepted at large requires some extra cultural encouragement and support, and some professional management of individual "skewing".

Once more, it's not that everyone has to be a hardcore expert in everything all at once. You don't want them to be.

You just want your main people to know each platform component well enough to be able to make a reasoned decision about the trade-offs involved in using one or the other for a specific task, and then to be able to own that decision as a group.

If they can't or won't do that, the platform decisions become political instead of technical. I've seen this over and over again, where massive technical problems are routed around because the Java developers have been told they can't touch Ruby, or the C# developers have been told they can't touch SQL, and the real problem never gets fixed, because we only recognize naive, scared "specialists" who insist that they can't learn Python because they're just a PHP developer, so they can't look at that piece of Python that's holding up the thing, instead of rounded, capable "generalists" who can be trusted to call in help when they're getting in over their heads, and may take an occasional "inspection" or two to make sure they're aligned with best practices.

General contractors are not electricians, but they can do a lot of routine work that involves electrical fixtures, sockets, and outlets. You call the electrician for the face-melting stuff.

General practitioner MDs are not dermatologists, but they can do a lot of work that involves routine skin disorders. They'll prescribe creams for fungal infections, rashes, acne, etc. They'll let you know you need to call in a dermatologist for the "skin-melting" stuff.

I apologize if I seemed particularly uncharitable, and I think you may well be right that I thought you were advocating for greater depth of knowledge than you were.

However, I still disagree with your premise that it's merely our attitude at large somehow holding people back. Startup founders don't refute my suggestion that there's a cognitive limitation involved, since they're relatively rare and may well have greater capacity to be the generalists that you're proposing. I'm also not convinced that, even among founders, they're as broad generalists as you're suggesting.

You go on to give non-computer examples of generalists and specialists, yet you don't address how it is that specialists are (admittedly only imoplicitly) ok there but not in computer tech.

To reiterate my point about cognitive capacity, if true specialists are desirable, then I allege asking them to be more of a generalist makes them a less competent specialist and therefore less valuable on the market. That's an alternate explanation for extremity of specialization than preconceived notions.

Now, personally, I share your desire for greater breadth of knowledge among all technical professionals, if for no other reason than they might have a greater appreciation for my own specialization. I just don't think it's realistic.

No need, it wasn't really meant to be directed toward your comment specifically. I just referenced that negative misinterpretations are inferred when the comment is grey as a way to remind people that it's not likely someone would advocate such caricatures.

> Startup founders don't refute my suggestion that there's a cognitive limitation involved, since they're relatively rare and may well have greater capacity to be the generalists that you're proposing.

You're right, and I thought of this when I used that example. But by the same token, we can take it out a level further: professional software developers have already shown themselves as having higher-than-average cognitive abilities, because the truth is that the average human doesn't have the cognitive capacity to become a professional software developer. If they did, we'd all be paid much worse.

How far off are founders from professional software engineers? How far off are professional software engineers from the median of adults? How much additional cognitive load is required to be operational in a handful of extra platform components, especially if all those components run the same type of hardware? All good questions that I don't think either of us have ready answers for.

The other thing is that even if this is out of reach for the "average developer", it wouldn't mean that it's not an ideal to strive toward, or necessarily even unrealistic in all cases.

> You go on to give non-computer examples of generalists and specialists, yet you don't address how it is that specialists are (admittedly only imoplicitly) ok there but not in computer tech.

Specialists should exist -- as external reference points in consulting groups.

If you want your life's mission to be building SQL queries, join a database consultancy and deal only with the SQL problems that your clients couldn't figure out on their own and decided they needed to pay $$$ to solve. If SQL and database design is truly your passion, you'll be much happier this way than you would be as a staff DBA redesigning the same rote EAV schema for Generic Business App #29, working slavishly to finish the code for that report that Important Boss #14 needs on his desk ASAP.

Creating a referral-style economy creates a lot more room in the marketplace for specialist consulting groups and gives more specialists greater reward (monetary and emotional). It simultaneously allows "generalists" to stay focused on the big picture of building and maintaining a robust and prudent system overall.

I think it's worthwhile to consider how generalist v. specialist operates in other knowledge fields, and what lessons we can take from that.

I am confident that a generalist ethos is for the best, but I'm not sure we'll get there without better cultural underpinnings, so I'm not making these statements purely out of self-righteousness (maybe only like 80% ;) ).

This dialogue has already been informative and has helped me refine my ideas and hopefully learn to present them somewhat better. Thanks! :)

cookiecaper 92 days ago [-]
Phew, this has been a good exercise. Let me clarify the thesis.

The thesis is NOT that a crew of superhumans can supersede all DBAs, security engineers, and infra people in the world.

It is rather that you can be a great software-side engineer, and that you can skew/focus on a few primary concerns, and develop and maintain a working knowledge in the others, sufficient to service your core project's needs.

Specialists can be called in as spot checkers, auditors, or short-term implementers, but they shouldn't be needed for the day-to-day of building, maintaining, and deploying your software.

In software, everything goes down to the same place: the system hardware. And these days at least, this is pretty much homogeneous between software segments. If you know how this functions, the differences are in the modes of expression and the conventions, not really the principles. We can learn the varying conventions well enough to be serviceable in all the elements that we send down to hardware -- not necessarily expert, but good enough for day-to-day work.

I'm not saying that everyone on the team should be better than the best DBA guy you've ever met. I'm saying that everyone on your team should be reasonably confident with SQL. Specialists have a place in your friendly local <security/database/whatever> consultancy.

Interesting that you mention this, since I think it's become something of a self-fulfilling prophecy, especially with giant cloud IAAS providers making one-size-fits-all choices of hardware to sell.

I certainly agree with you that that the basic principles are certainly the same, but that ignores the performance (and, arguably, reliability) possibilities that open up when not limited by the hardware (including network) choices of others.

> Any separation is ineffective except along this one particular completely arbitrary dividing line? If that were true we'd still be hunting and gathering and nothing else.

Hardly arbitrary -- hardware is fixed at the time of manufacture. Hardware engineers should be well-acquainted with software concerns and needs, but the years-long feedback cycle and real expenses associated with hardware development creates a natural barrier for work separation, requires different work cadence and much more stringent processes, etc.

This is not to say that a good hardware engineer shouldn't contribute to software and vice-versa, but it is to say that the roles are sufficiently divergent that it makes sense to place them in different segments. That is not the case with anything this side of the operating system, as far as I'm concerned.

> It's arbitrary when you claim there are no sensible divisions in software.

It's about the fungibility of the problem space. I don't know how you expect your core team to make reasonable decisions about the tradeoffs if they a) don't understand more than one of the platform elements; and/or b) don't have any responsibility or accountability for the tradeoffs that get made, because now it's another segment's problem. Indeed, when I've been on teams primarily comprised of non-generalists, these decisions were almost always a matter of bureaucracy and politics.

> I think your entire lengthy argument is a sort of elaborate, lengthy fantasy about how much better the world would be if everyone was just like you or at least, just like you imagine yourself to be.

I've worked on teams that were mostly "generalist" and teams where the "generalist" type was either absent or artificially constrained. My perspectives are drawn from those experiences, and have developed based on a hard-earned worldview that says people reliably act in favor of their own expedience. Doesn't seem very fantastic to me. ¯\_(ツ)_/¯

> shackles placed upon them by sysadmins

Well, potentially unpopular opinion here, but an awful lot of sysadmins brought their looming obsolesence on themselves. I'm an app (as in "a program that runs on a computer", not an iOS add-on) developer, always have been. I get requirements from the business types, code it up in vi or Eclipse or whatever, get it working, and then they (the business) want to deploy the working app out to production so people can use it and the business can make money off of it. And, for decades, sysadmins have been a brick wall of pure hostility. They're not all like this, but a lot more are than aren't. Like, I get it - you're overworked and the demands on you are unreasonable. Yeah, me too. But I just work here, man. You're right, I don't know how to do your job, that's why I sent you an e-mail asking you what steps are needed to deploy an app into production since it's not documented anywhere. But rather than just tell me what you need so I can go gather that up, you're going to unload on me because you feel overworked and unappreciated, but you're sure as hell not going to unload on a manager or somebody with actual power, you're going to take it out on the developers who have no pull or voice.

Actually, as a sysadmin, I sympathize with you, since I consider that kind of situation to be a sign of, essentially, bad system administration. It also sounds like it might be at a larger company.

I feel like there has always been a contingent of sysadmin / ops folks who preferred the "Better to ask for forgiveness than permission" model. They still hate when things break, (so not quite fans of developers with a "move fast and break things" philosophy) but they care more about big picture improvements and ease of upkeep than enforcing any particular process. Detecting problems and being able to roll back is typically more valuable than preventing mistakes in many cases. It may be somewhat driven by laziness, but it actually works out pretty well for collaborating with the fast-moving developer types. It also does depend on being in an environment that is tolerant to occasional mistakes or outages.

It makes sense that these types naturally gravitated towards the devops models. I'm really not sure where this leaves the more compliance-minded systems folks though.

mr_tristan 92 days ago [-]
This is definitely a rant that obscures the underlying point: the introduction of _untrusted_ or _unreliable_ network resources, frequently hidden in a string of dependencies.

I'm baffled how often I see an someone throw this sort of craziness - "go fetch this thing from some random third party" - into very important places, such as the startup procedures of a container. It's something I see in a culture of the two person startup just trying to get something out the door. It's definitely "technical debt", and frequently, it won't get removed. Thus, you try to scale up to meet load, and all these new instances go time out on the same external resource that's randomly having problems... boom! At the worst possible time. Never mind the potential huge security gaps.

But the specific _tools_ aren't the issue here. It's the culture of "ship something now we'll deal with fallout later". A lot of people start using Docker and won't ever look at the Dockerfile, or, will add a Maven dependency and won't even check licenses or security updates for _any_ of the transient dependencies.

Cloud technologies and containerization make everyone just think "we can do things so fast now" and never, ever pay attention to details that can come back to bite you.

On the flip side, it's a good time to be in cybersecurity; because this cultural problem will never, ever, get solved. :)

borplk 92 days ago [-]
At the end of the day it comes down to the fact that businesses just simply don't care (Equifax etc).

They like the idea of security and that's where it ends.

In many places if you try to "do things right" you will get fired in two months for being too slow/strict and they will happily replace you with a clueless easily trusting person who "goes and fetches things from random third parties".

Many times they get lucky enough to survive and they don't appreciate the risks that they took. That pace becomes the expected norm and sets the theme in the industry.

And when shit hits the fan the PR person writes a "we are oh so very sorry .. security is totally our number one priority" blog post. They blame and fire the poor bastard and replace him with another warm body.

When it comes to these "hidden" things like security companies do not reward and also punish "doing things right" so on average and over the long term we end up where we are today.

When the culture sufficiently shifts towards being sloppy you will get hammered down quick if you try to be the voice of reason because it ends up being you vs everyone else (the norm).

commandlinefan 92 days ago [-]
> just simply don't care (Equifax etc).

And, honestly, why should they? Security breaches have yet to hurt an actual company (they hurt users plenty, but not the organization that's actually responsible).

mr_tristan 92 days ago [-]
Data breaches are climbing in cost to organizations. Here's a claim, that in 2017, the average breach costs $3.62 million. https://www.scrypt.com/blog/average-cost-data-breach-2017-3-...

(I've seen similar claims in different ranges. Costs of breaches in the US are pretty high - over $7 million.)

Even Equifax probably wants the 3-4 billion in valuation it's lost since the breach.

The solution appears to be buying tools to avoid and respond to breaches quickly, instead of engaging and building in security awareness. (Microsoft's security development lifecycle comes to mind.)

IMO, both approaches are likely cost effective, though I have no numbers or research to back that up.

this is a very naive way of setting up a secure production enviroment.

Your perimeter security is worthless if you are loading non public images which have malware or even worse, unknown malicious code in them.

having a data breach or hack on your hands is something which could kill the company. That risk is not worth having a slightly faster productivity boost because you or your ops team is not able or willing to build a proper private repository setup.

Huh? Old-school sysadmins know how to keep systems running, manage updates and upgrades. At the same time nobody knows how to build Hadoop from scratch. At the same time, Hadoop build instructions themselves have curl|sh scripts or mirrors and the wiki page is outdated. And it uses Java (and thus maven/ivy). And that downloads the internet.

According to the blog, Hadoop, maven/ivy/sbt/any dependency manager, package managers, and everything is broken. But the tagline is:

What does any of this have to do with the "Age of containers" and pre-built VMs? Is the author just talking about Gentoo/LFS-style "compile the whole system from scratch"?

There is SSL/TLS, unless it's done wrong (invalid certificates get ignored by the dependencies manager), it's safer than the old "md5 of the file" systems.

Now, some dependencies are fraudolent (especially true in the Javascript world because it eventually targets a lot of user browsers), but nobody ever checked the sources anyway...

cesarb 92 days ago [-]
TLS only verifies that have connected to the correct server. It can't verify whether the package on the server has been replaced by a malicious one. For that, you need a "md5 of the file" (these days, a sha256, because md5 has long been broken).
dullgiulio 92 days ago [-]

Which isn't really true; as a sysadmin (I'd say "former", but once you're a sysadmin, you're always a sysadmin), I've seen lots of things with horrible build and dependency nightmares, and that was before package managers, containers, and virtual machine images became de rigeuer.

Think of a self-hosting programming language: you can't build it without a running installation of a previous version. (Anyone remembering "On Trusting Trust" at this point?) Or any application in an image-based language like Smalltalk. Development becomes path-dependent. It's inevitable to get into a situation where A and B cannot be made to work together, except in a derivative of a version that someone, somewhere made while holding their mouth the right way.

Pre-built containers and VMs are an admission that path-dependence is the way stuff is supposed to be.

I've seen this brewing for a while, and getting worse and worse. Back in the 80's and 90's, there were developers who would code their own sorting or hashing routines rather than linking in some external library to handle this "solved" problem. The perjorative term "Not Invented Here" (NIH) grew to describe those developers and they were shamed into reusing code whenever there was code to reuse. And in some cases (like sort routines), it makes perfect sense. However, NIH accusations have grown to "if there's something vaguely similar to what you're writing, you must use it, even if that involves more custom coding to artificially bend it to the case at hand than you would have developed in the first place", culminating in things like the completely empty, useless (but enormous) Spring "framework" or, to a lesser extent, things like Angular that sort of do some things, but create far more problems than they solve (and definitely add more development overhead than they remove).

The author should have grabbed the .sdeb or the debian build scripts and tore them apart if they really wanted to make a point (if, upon examining the build, there was one to make).

I mean there is a lot of cognitive load/disconnect we're talk about. As an ops guy, I can't look into every package. That's why I trust the package manager (apt-get, yum, whatever) and all the build maintainers who either volunteer or work on for Redhat/Canonical/SuSE/IBM/whoever.

Things get through. That's why we have all those security people out there who are digging around for bug bounties and find crap like the recent Ubuntu Snap package craziness.

Docker containers can be good. You can use an official Ubuntu or Alpine image, build your base, and create scripts to make sure your base containers don't go out of date. Most people don't do that. The official Docker containers are kinda a mess, but at least they're maintained. Grabbing some random container off Dockerhub? Yea that's not going to end well; unless you just use their source to build your own. Or if it's a container continually maintained but the person/company who wrote the service.

Docker containers do need better security introspection and that's going to be a big deal going forward. But this article is all rant and some, but not enough, substance.

Makefiles aren't scary. But they're also not particularly good.

I use Rake (or Gulp, or whatever) because then I can use Ruby (or JavaScript, or whatever). Shell plumbing is fine for informal and small-scale stuff, and I make my code conform if somebody down the line (who may be me) wants to get out their duct tape, but the world is more complex than what /bin/sh can see. Shell is the lowest common denominator. Expecting everything to at all times be written in and for that lowest common denominator is not reasonable. We're a tool-using species and we refine tools over time to make them better. The profusion of tools happens because they iterate on each other to be better. If old tools were sufficient, people would use them because learning new ones is hard.

So, yes, you do need to learn those tools. Or invent a shell that isn't tooth-pullingly difficult to use with a JSON file (and do not say `jq`, I love `jq` as an inspector but it does not step to `JSON.parse` and a working subscript operator). Or change `make` so that a git checkout won't trigger a full rebuild. Lots of baseline, stump-simple things that `make` is just not going to do for you because it's built for a frankly outmoded method of development.

Ha, that's a neat trick! Trouble is, for either Python or Ruby it becomes tricky due to stuff like dependency management. You'll have to `bundle exec make` to get sane library paths for Ruby or `pipenv run` for Python, etcetera etcetera.

At that point I think you might as well just use a language-native one.

Great pull, though.

avar 92 days ago [-]
The GP does this via a neat hack, but you can also do this in a much more understandable fashion by simply having the body of every Makefile rule start out by shelling out to some script in your favorite language.

I think you're (understandably) misinformed about what Makefiles do because you've run into some bad ones. The thing they're doing is managing a N-level deep dependency tree in a declarative way. So if A->B->C you can run something to generate C, then B can run, and finally A, and this can all be done in parallel for hundreds of files.

On the individual rule level this is really simple, e.g. just turning a .c file into a .o file, then finally some rule that depends on all *.o being generated creates a program out of them.

The language-native ones are usually much worse. They're easier to use at the outset because they don't make you create this dependency graph, but that also means that they can't run in parallel on your N cores, and they usually suck at incrementally updating the build.

> The GP does this via a neat hack, but you can also do this in a much more understandable fashion by simply having the body of every Makefile rule start out by shelling out to some script in your favorite language.

I'm not sure what you mean? How would this allow you to use, say, Python as the language for recipes? Just having Make drop straight into Python kind of defeats the purpose of Make.

avar 92 days ago [-]
You'd use Python as the language for the recipe that turns (in this example) a given .c file into a .o file, while leaving the Makefile to do what it's good at, declaring the DAG dependency tree needed to incrementally build it.

The point is that people conflate these two things. They open some random Makefile and see that it's mostly doing stuff with shellscripts, and think "oh I should do this all in Python", and then write some monstrosity that doesn't make a dependency DAG and thus can't run in parallel or be easily understood.

Instead they should have split the actual logic they found in shellscripts in to Python scripts the Makefile invokes.

Nevermind, I misread you. I missed "rule" where you said "beginning of every Makefile rule". (I thought you were suggesting just having the default rule run some enormous Python script, which I've unfortunately seen before.)

Is it that hard to learn shell? Why is it so painful? What makes it the "lowest common denominator"? I use it all the time, but I admit at work I am one of the few.

> Expecting everything to at all times be written in and for that lowest common denominator is not reasonable. We're a tool-using species and we refine tools over time to make them better.

This is too vague. What makes a Ruby based build or JS based build a more "refined" tool? It sounds like familiarity is the real issue here.

> If old tools were sufficient, people would use them because learning new ones is hard.

How many people even know Makefiles these days anyway? The "modern" approach seems to be, learn a programming language and then try to do everything inside of it. Some languages are more interested in this cloistered philosophy than others (like JS).

If anything, I think the reason these build tools keep being proliferated is because nobody wants to learn anything more than the bare minimum to "be productive" (which, depending on what you're working on, can be anything from pushing out customer demos for a company that will never sell, to microservices operating at scale). Learning a language and never leaving its paradigms/comforts is easy.

adamc 92 days ago [-]
Your second paragraph got to the heart of it. If we want to use some standard build toolchain, it needs to use a nice language and not feel obscure. I was explaining to someone a bash script I wrote, and he said "why not use Python". There were reasons but... he was right, Python would be much easier to use and maintain, and we have a lot more developers who know it.

That said, Maven is incredibly suck-tastic.

Eh. It's not my favorite thing out there, but Maven's fine for what it is. It's designed for and explicitly for well-behaved Java artifacts.

Clunky is subjective -- I think we can probably agree that there are clunkier, more opaque, and harder to work with constructs in programming than a slightly different syntax for array declaration.

You're right, there are clunkier, more opaque, and harder to work with constructs in programming. Like `sh` arguments. And like `sh` quotebarf.

And Busybox is commonplace. Systems that include Busybox usually do not include `bash`. And so, for my purposes, if I can specify `bash`, I can also specify, say, Ruby, which--while by no means perfect--makes life much, much easier.

I disagree that it is the wrong question. "Every other language" doesn't matter because I don't value homogeneity and I think that homogeneity of programming language is a fool's errand.

"Restricting that environment" is appropriate in some environments, and a number of my clients bring me in to help with that.

Makefiles are definitely not shell scripts. Individual recipe lines are executed using Bash by default, but you can change this. (Heck you probably could even get away with Python if you really wanted.)

The rest of Make (which is 95% of what's in a Makefile) is its own language, which is actually not too bad for what it's intended for (munging around filenames), and has the flavor of a functional language.

My real issue is the constant wheel-making impulse, that leaves us with a shattered landscape of people tripping and falling over busted-ass and abandoned wheels. I have a JavaScript front-end project that uses three different package managers, and four different make-analog tools, plus some batch files sprinkled on top to orchestrate the common use cases of this monstrosity. Nothing that we are doing here is that complicated, except for this sea of shitty half-baked ecosystems around these tools, each of which was considered best-of-breed at one point.

What we want to do is slurp some text files up, apply some transformations to them, glob them together, run them through the minifier, and dump them into a final output. This is exactly what a decent makefile would fit well for. Instead, I got this, because apparently nobody wants to use anything that isn't the hot new way to do things, and so very few people have even had enough exposure to know that there are tested tools for these kinds of things that existed. The last time I was using make beyond trivial uses was a decade ago in college (incidentally, I actually did build jars with make, easier than fighting Eclipse...). But just knowing that something exists is more than half the battle, although the problem then is that it's frustrating as all hell watching the same ideas cycle round and round and round every couple years.

I'm not familiar with either of those particular two tools, and what you say may well be absolutely true for both of them.

It's just that this argument keeps getting used for every single new "reinvented wheel" (to borrow from the GP). Sometimes the argument is as strong as "it couldn't be done any other way" and sometimes it's as weak as "this one is just incrementally better," but it feels a little like crying wolf.

Was it really "very hard" to make the old wheel do what you needed, or perhaps somehow extend it or add a library, or was it just far more fun and exciting to build something from scratch?

I generally don't mind a proliferation of tools, except when they start to break or conflict with each other, which is, I believe the GP's main concern, and at least tangentially related to the article.

Sounds like you're describing make on a system with ccashe installed. Hashing incurs a significant performance hit. The first build with ccashe is 20% slower than building without it[1].

Language specific build tools will usually behave predictably across all development platforms supported by the language.

In reality it's all peachy until stuff doesn't work and no one knows why, or how to investigate an issue or remotely where to begin to troubleshoot it.

I think that may be hehind some of these tales of 'luddite sysadmins'. Sysadmins need to keep things running and complexity and dependencies, even if they being convenience is something that makes them nervous. It's not about being a luddite, its about being able to hold a mental map of how it all works, so that when it stops working you can dive in.

And not to mention getting called at 2 am because something didn't build or the release bombed and having to examine, for the first time, some over-complicated mechanism to build things that goes through some pipeline where you're eyeballing large log files full of long exception chains.

Devs see the world as one where velocity and progress is among the most important, while 'sysadmins' (a term no longer used by companies and recruiters, unfortunately) have to worry about keeping the applications actually up so they can be used.

DevOps just seemed to have swept the sysadmin under the rug under some pretty words about breaking down barriers. It feels more that devs broke down the wall sometimes. The amount of infrastructure chaos and mess and confusion I see today (as a contractor bouncing around different places) seems higher than traditional infrastructure shops of 10+ years ago.

This is very true. Having a mental map of how things work is vital for correct (and good) troubleshooting.

Also, a ton of people use abstraction as an excuse to not learn a body of knowledge that contains fundementals (especially on the systems side).

In comparison to network engineering for instance, where having (quite) low level knowledge of how protocols work and interact with each other is vital.

I used to try and convince them otherwise, but it turned out to be a completely futile waste of time.

Every build system is like Make, but more friendly for their language (IIRC Make was originally for compiling C and C++). Make just so happened to become generic enough to build damn nearly anything and also get bundled into most Linux distros.

I think the author is arguing that having to install a shit ton of dependencies to use some other Make-like build system is garbage. That’s true in some cases. But I wouldn’t want to use a Makefile for packaging Node; npm is great for that and understands how Node works.

If you thought having to deal with old COBOL programs was a problem, it gets much worse. When there are 10 year old containers in production, and the parts to rebuild them are long gone, then you have a real problem.

The right answer is to use your own repository and pull those images in-house where they can be scanned and verified, I.e. , run a container from that image, scan it using security tools, then action from there.

You can also kind-of recreate a Dockerfile from an image using docker history: https://stackoverflow.com/questions/19104847/how-to-generate...

This is why we have a local registry and for any container that is goes to testing or production or is needed for builds should be build-able from source.

Hadoop is a rather extreme example... It's bad, but not everything nowadays is. Many newer pieces of software install entirely from source with one command.

Also, this is not at all endemic of containers, there's simply zero connection. Dockerfiles tend to be very simple and easy to reason about. The most complex application I have is around 50 lines of Dockerfile, and that's mostly just made more complicated to arrange things for the best layer caching.

I suppose we're supposed to believe that this is somehow worse than the days of debugging m4 macros and autotools just to get a build that doesn't work.

Does that Dockerfile build a container that only has that app in and it's required dependencies? Almost all of the ones I've seen given as examples seem to have an entire copy of the OS in.
jchw 92 days ago [-]
A container is basically a glorified chroot, so there is a few things not strictly needed, but I typically use Alpine as a base system, which has a shell, some core utils, and musl libc in just ~5 MB. Since it's on its own layer, it gets deduplicated both in build and at runtime with other Alpine containers (and many Dockerhub images have an Alpine option.)

That being said, since Go binaries have no inherent dependencies, I have indeed made Docker images containing exactly one file: the Go binary. These containers are basically the same as fat binaries, with the benefits of Docker scheduling and networking at runtime.

seabrookmx 92 days ago [-]
> I have indeed made Docker images containing exactly one file

To anyone reading this, you need some magic compiler flags in both Rust and GoLang to make sure it's a statically compiled binary (doesn't dynamically link against GNU lib-c).

But yes, this is super neat. I also like how it reads in the docker file:

FROM scratch ...

Ah yeah, without CGO_ENABLED=0, you'll get a very cryptic error when the ELF binfmt can't find the linker binary...

Never tried it with Rust, but I look to using Rust in the future, so I guess I better find out what the flags are for Rust.

Sidenote: It's often useful to have ca certs and timezone info. At that point it's probably not a bad idea to just use Alpine and apk add those things.

steveklabnik 91 days ago [-]
By default, Rust compiles all Rust code statically, but the standard library depends on a libc. If you want to use MUSL, you can. If you bind to C libraries, you may need to configure it or not, it depends on how the wrapper is written.

I believe this is true and if so, then the argument should be against package managers, not Docker specifically. Most (if not all) of the official Docker images are built either by compiling the binaries from source, properly installing the binaries from the base distro's package manager, or pulling and verifying a pre-built binary from the vendor's website. For most cases, I don't see anything wrong with any of these.

Personally, what I like is no longer having to setup arch specific build machines containing all of the build tools and dependencies for all binaries that I wish to self-compile. Instead, I either use the vendor's Dockerfile which already contains everything it needs to build from source or I simply write my own if there is not one available. Building and distributing these binaries in the form of Docker images is a breeze using Gitlab CI and container registry and is just as easy with a small VPS and Docker Hub.

mmt 92 days ago [-]
Actually, I think there's a subtle distinction everyone's missing (which the original article may or may not have been making):

Unless one can compile it oneself, how can one trust that a particular version of a binary release correspond to a particular version of a source release?

If the process is reproduced by another trusted-enough source and is identical to the official release, then I'd say one can go ahead and trust the binary release of either one.

Sadly, I don't think this is generally done, though perhaps ones own spot-checking of the official release is enough.

That's supposed to be the basis of modern science, too, though, of course, it's not generally done there, either.

I think the only reasonable answer is "it depends".

After the new updated base OS images for our systems after Meltdown and Spectre were out, it literally took us ten minutes of human and about an hour of machine time to recompile all of our containers, run the tests and deploy them to production on our Kubernetes cluster, replacing the old insecure ones.

At the scale of our systems, any grumpy sysadmin would have spent at least several days untangling the dependencies and carefully restarting all servers in the correct order after some manually `sudo apt-get`ing (and probably forgetting a few of the lesser used systems).

Sure, typing "FROM ubuntu" (which by the way is a trusted and cryptographically image, contrary to the OPs concerns) leaves me at the mercy of whoever I trusted compiled that image.

Then again, what difference does it make to trust whoever compiled that ubuntu-17.04.iso image I put on my CD?

Or, as Brian Tracy taught me to say in these situations: "You may be right."

if you are operating at suchs a large scale, your sysadmin should be automating things (not necesserly with docker mind you).

This automation has been possible on *nix for the better part of a decade by now.

mmt 92 days ago [-]
Agreed. As a (potentially) "grumpy" sysadmin, I wouldn't be manually apt-getting or forgetting anything. In fact, one of the lessons I've learned is that, at large enough scale, automated mass upgrades can do the forgetting for me, so verifying (also automated) is important.

As for any "tangle" of dependencies that may exist, I've never seen that be caused by any choice made by "Ops" but, rather, solely by those writing the appllication code being deployed. As such, it would apply just as much to a Docker image as to (what I view as) a traditional deployment.

not to be pedantic but why should containers be patched for security issues?

the entire point of containers (and orchestration systems) is the ability to push updates without downtime.

Just update with a newer container....am I missing something?

Also about container security - a strict process internally can easily help counter that (I believe Shopify had a nice talk about it at the Google Cloud Platform event in Toronto - everything from using trusted images, running only signed images and going through a security check for each layer).

EDIT: To add to it, please don't patch containers - the entire point of an "image" is that if I run it locally and on my datacenter - it should behave the same - live patching them just voids this concept.

Perhaps interestingly, I've had some similar complaints about package managers like homebrew.

I've noticed over the last decade that a certain level of knowledge about building from source seems harder to find via search or engaging in a community forum/chat. The assumption is often that everyone will be using the package manager (I'd say that's especially true on macOS, but it might be an artifact of me spending more time there since it's been my most used dev machine), so if you have trouble building something, the answer will frequently be "just use homebrew -- whoever maintains the formula will already have solved your problems for you."

There's two problems with this: first, that's presumably true for the source build, and if you can hit a case that the source build doesn't work for, chances are pretty good you can hit a case that brew doesn't work for (my experience is that more often than not they go together). Second... I'm happier to use package managers for applications meant to live on my machine and never go live elsewhere (heaven knows there's lots of stuff I just want to install and get on with my life rather than fiddle with), but for applications I'm deploying, it seems to me it's generally wise if someone involved in the project has a picture of the build details and dependency graphs in their head.

Some of the automation we're throwing at operations is really convenient. It's not simple, though. And depending on how much forethought is put into it, I'm starting to think of it as ... maybe not technical debt, but a technical credit card which is super convenient at times, but also can easily become debt if you're not careful with it.

nunez 92 days ago [-]
Nah, you’re right

The entire purpose of DevOps IMO was to close the gap between sysadmins and devs through code. Devs doing everything, including infrastructure, was and is the entire plan! Public cloud made this super duper easy.

The problem is devs don’t want to manage core infrastructure (VPCs, networking, modules for deploying lambdas and database clusters and container orchestration clusters, etc) and somebody has to do that stuff

Ideally, those would just be features like any other software team, as it’s all API calls at the end of the day. But lots of companies have issues with structuring their platform teams like software teams because its “not software” even though it is

This problem is more deeply entrenched at large companies with hundreds of millions of dollars of compute that they own that is owned by an old school IT function that can’t fathom the idea of either giving it up or making it accessible like cloud and would rather pay VMware tons for tools that make teams even slower than have their sysadmins become developers

Then there’s the whole protectionist “You’re taking my job” and “devs can’t possibly know this much about $infra” that isn’t dying off anytime soon

It’s complicated

> Ideally, those would just be features like any other software team, as it’s all API calls at the end of the day. But lots of companies have issues with structuring their platform teams like software teams because its “not software” even though it is

Just because it's is implemented as API calls at the end of the day doesn't necessarily make it not "not software" (if you'll pardon the double negative), at least in the sense that I believe you mean.

To whit, I believe you're suggesting that if something can be expressed as code, it's all "software" and can therefore be designed, written, and maintained by the same kinds of experts, software developers.

I disagree, because the nature of the infrastructure-as-code code is too different from the application software code.

One could, similarly, express an FPGA configuration in code, but a software developer would not automatically be good at programming one. This is even likely to be true for less extreme examples, such as programming expertise not automatically transferring from general software (for lack of a betterm term) to code that works well on, say, GPUs.

In the case of IAC "software", a more mature design is more likely to resemble traditional sysadmin/network/security best practices than application software features. It could also have significant financial side effects if there's an error, assuming public cloud, which could require more stringent standards of control, review, and quality, especially if a company ends up in SOX territory.

>Then there’s the whole protectionist “You’re taking my job” and “devs can’t possibly know this much about $infra” that isn’t dying off anytime soon

I'm sure some of this exists, but my own experience is an attitude not that devs can't know a certain amount about infrastructure but that they simply don't, often because they actually don't want to.

Perhaps they fear that if they do end up knowing that much, they'll end up being the ones to manage that core infrastructure, which you indentified that they don't want to do!

I'm not convinced there was ever a need for sysadmins, especially from the point of view of programmers. Programmers have always been able to do that work themselves.

It's just that they don't want to. They think it's boring, or perhaps even beneath them. It's a bit like tax preparation.

I don't think that's really changed all that much, even today, even if it's now programming against the AWS API, judging by the number of job postings for such a role.

Also, like with tax preparation, using a good expert instead of doing it oneself could save on a lot of money and/or future headaches, but it can come with "grumpy" old-fashioned-seeming nagging about procedures akin to annotating and saving receipts. Whether it's worth it depends on situation and, far more importantly temperament.

I'll half agree here, and half not. I'm coming at this as a programmer who has historically done ops as well, currently doing more ops than dev.

There's parts of it that programmers don't want to manage, like Apache configuration, provisioning and sizing VMs appropriately, etc. That's the boring stuff, and I totally get it. I don't like managing most of that stuff either, and have got everything set up with service discovery to handle a good chunk of the configuration, and Terraform for managing resources instead of having to click through the Azure Portal, and Nomad for scheduling tasks in the clusters. Groovy.

There's also the parts that the developers seem to have no clue about. They're very happy with all of these abstractions, but there's a lot of layers underneath. They think in terms of making HTTP requests; when those don't work, it's up to me to figure out that their library is keeping a pool of HTTP connections open, and the Azure load balancer silently drops those connections out of the NAT table after 4 minutes of idle time (without sending FIN or RST packets to either side, natch). When the app gets terminated because it's exceeded its cgroup memory limit, I'm the one helping them adjust their JVM heap size. And when their requests take too long, I'm there helping them look through their query logs to figure out what's happening.

All of these cases have happened in recent memory, and it's never been a matter of "this is boring and/or beneath me", it's been a matter of "HALP! I HAVE NO IDEA WTF IS HAPPENING"

Edit: so yes, I agree with you in the sense that I'm a developer who generally speaking doesn't need a sysadmin. I installed Linux for the first time when I was 12 years old, 22 years ago :), and I didn't have a sysadmin then. In those 22 years, I've seen a lot of weird shit happen, and most of the people I've worked with don't seem to be well equipped to dive 3 abstraction layers deeper than they're used to to figure out what's wrong.

These two cases strike me as actually one case, with the former being the cause and the latter being the effect. At least that's my contention: they had no idea wtf is happening in those lower layers because learning them was beneath them (no pun intended). Nothing was really stopping them from learning about heap size versus process/cgroup limits.

On the other hand, you do bring up an important point about (mis)behavior of network infrastructure. That's not something the average programmer would necessarily encounter or have access to, especially at scale, and therefore wouldn't be expected to know. Still, my point still stands: there's nothing stopping programmers from gaining that knowledge if/when it becomes necessary, should they want to.

Now, I'm not trying to play dumb. I mostly don't want to read too much between the lines. Are you, in essence, saying that your half-disagreement is that sysadmins are needed, not because (average) programmers don't want to learn all those layers, but, instead, are incapable of learning them?

tonyarkles 91 days ago [-]
Very very excellent points. I think that everyone on my team would be capable of learning them, but at least in this specific case it's not so much that they feel it's beneath them, but more of a fear. They talk about C as if it's something that only dark wizards understand, likely as a result of poorly taught early CS.

I think what I'm saying is that I feel like sysadmins are frequently needed for sake of expediency, especially when hiring younger developers. And maybe, due to that same bias, I actually mean "senior developers who understand abstractions several layers deep" :)

Thanks. That's a point I hadn't considered.

I'm not sure that expediency translates to a need, as such, but that situation is certainly different from the one I envisioned (where a sysadmin is merely a luxury or an optimization to the programmer-DIY-ops scenario).

> I actually mean "senior developers who understand abstractions several layers deep" :)

I'm not sure you do, since you admitted to really being at least part sysadmin, earlier :)

tonyarkles 91 days ago [-]
> I'm not sure you do, since you admitted to really being at least part sysadmin, earlier :)

Hah!

I wish I could remember which talk it was. Bryan Cantrill had a good line about DevOps in one of his talks (I think it was this one: https://www.youtube.com/watch?v=30jNsCVLpAE). The gist was "you can say you're DevOps, but when the shit hits the fan, you're either going to be Dev or Ops. If you're a Dev, you're going to want to debug the problem before rebooting the failed machine. If you're Ops, you're going to want to reboot the machine as fast as you can to get it back up." Through that lens, I'm definitely pretty far over on the Dev spectrum; when something goes catastrophically wrong and someone reboots a box to "solve the problem", my first reaction is "YOU FUCKER YOU BURNED THE CORPSE"

It's such a tricky thing all around. Looking back at what I wrote earlier, I also realize that in some ways I'm facilitating the ignorance. I've got a really nice Consul and Nomad setup for the team, so they can pretty much just toss .wars and Docker containers at the cluster and they'll automatically get scheduled somewhere with spare capacity. The load balancer, the database cluster, all of the service discovery and job scheduling stuff... they've never had to get in and set any of that up. Maybe it's time to do more mentoring...

Anyway, thanks for getting me thinking. I've been a little bit grouchy lately about all of the recent experiences of people not knowing how the stuff they build actually runs. You've been a great mirror for some self-reflection :)

Edit: also, bare metal rocks.

He's right that security right now is a bit unreliable but random sysadmins writing scripts and manually configuring things is never a good guarantee either.

As a dev I'd like nothing more than k8s or similar to be the standard platform to run applications so that everthing is standardized and I dont ever have to require a sysadmin. I think already this is possible more secure than the "good old days", but in the future I expect it to be more so.

nineteen999 92 days ago [-]
Thank heavens people are starting to point this out.

The last devops team I worked on had an obsession with shiny. Never mind that they couldn't bootstrap a new base database for their application anymore or automate the entire application deployment (even with a phased approach) on either VMware or AWS. They wanted to keep piling new tools (often with sub 1.0 version numbers) of new tools on top of an unstable foundation, and would just shrug when it fell apart in production (which it commonly did).

I tried pointing out to them that by giving commit access to their internal puppet git repository to every developer in the building, they had effectively given root access to them as well. All I received were shrugs and blank looks all around.

One thing from the article that doesn't seem to be discussed enough here in the comments is trend of pulling random Docker images from the internet and deploying on your infrastructure simply because it's easier to integrate random versions with feature X than maintain your own builds, or work with the vendor's provided packages to achieve the same result. The security implications of this in particular has been bugging me for years.

I think a lot of stuff that I used to need to know —- OS kernel internals, hardware specifics, relatively deep network knowledge —— is less useful in the age of public cloud, containers and immutable infrastructure. There isn’t really a need to tune a kernel for performance or do deep troubleshooting to root cause OS issues and ensure uptime; if something seems off, kill the machine or container and let auto scaling or the container orchestrator take care of it. If something wrong with cloud networking, call AWS, as the most we can do is prove that it’s on them. Etc.

While I still know these things, I haven’t had to employ them in a while. I will probably use those even less as I start getting into management. That’s a bit saddening.

But the new stuff I’ve learned over the years, namely, designing systems like I’d design software, is amazing. Applying TDD to infrastructure isn’t something I thought I’d be doing, but here we are, and we have “modern DevOps” tooling (and lots of other things) to thank for that.

100% this. Learning Make a few years ago was one of the best decisions I’ve ever made. It’s simple (until it’s not), straightforward and available on just about any Linux and UNIX installation (version compatibility aside).

Trying to make the case for POSIX-compatible Bash scripts has been tough, though.

I also agree re: Docker. While you can secure a container image with USER statements in the Dockerfile and knowing how to give containers just the capabilities that they need to do their job, it is WAY too easy to run them as root and give them privileged access to things. It should’ve been the other way around. Also, every container orchestration platform seems like a really elaborate hack.

davexunit 92 days ago [-]
nixpkgs isn't rigorous about reproducible builds. Hadoop is actually a great example of this. They do not build it from source, a prerequisite for calling a build reproducible. Instead, they download the binaries that the Apache project has already built and run patchelf on them to make them work.

https://github.com/NixOS/nixpkgs/blob/master/pkgs/applicatio...

ixxie 92 days ago [-]
That is true, but in my experience in small scale personal desktop and cloud computing, NixOS is in practice reasonably reproducible on the system level.

For me in terms of interface, the strength of the Nix ecosystem is declarative system, ops and service configs in the same language used for package and build specification. The technical strength is striving towards reproducibe builds by hashing the dependency tree to build an immutable store. Yes sometimes this means getting binaries but you can always pin the package version or even have multiple versions in tandem. The practical upshot of this immutability is system level rollbacks, which are generally reliable although there are ways to break it. Yes there is garbage collection.

Nixpkgs has is quite an achievement, and yes it has its warts but we are working hard to make it better. If we manage to shape up the data science I will try it out at work too. Im very curious how it might scale.

batoure 92 days ago [-]
I don't disagree with the OP here per say.

However I do think OP made a mistake by using Hadoop as the example. Hadoop has much more in common with an OS at this point than a single application. The ability to download a single component of the eco system is mainly to support small scale testing and development.

You wouldn't build Debian by going and getting each piece of the linux kernel from its source building those building all the pieces of the middle ware up and so forth... that is the whole point of having Debian in the first place.

Do certain complex software eco systems need better support for fingerprinting their builds, Yes. Does all this mean the sky is falling... probably not.

disordinary 92 days ago [-]
There's always been propriety code installed on systems, who knows what that big Oracle database is actually doing?

Are these sysadmins actually looking through the open source code that they're compiling to make sure that there isn't a security flaw in plain sight?

With Docker you can get containers maintained by a trusted source, as a sysadmin you don't have to deal with all the hassle of upgrading things, you can just replace the container with the latest version. With Docker content trust the containers are signed.

There have always been cowboys out there and that has nothing to do with the tech stack.

If a company has a threat model and a list of business goals then they would have at least a risk matrix and they might decide what to do: either go the slow way and build software they can trust or accept the risks, backdoors and all the rest. Most companies skip all of that and hope for the best. Not always a conscious decision.

Sometimes they get their unpatched servers encrypted by some ransomware, remember they don't have any backup, close shop and move on to the next business idea. I've seen that happen.

Security is what the article is about, and it is spot on.

Cloud infra today requires coding skills. Thats why so many web developers trying to do infra too. Without systems or infrastructure knowledge.

True cloud automation engineer, a.k.a DevOps, a.k.a SRE, is the sysadmin learned to code more than bash. Python, REST, classes, methods, objects.

Or web developer, learned Linux and networking in deep, down to userland to kernel system calls and routing protocols.

These people are rare, hence the ruckus and mayhem. You will be hacked.

hodgesrm 92 days ago [-]
I see this as more of an opportunity than a problem. The fact that Hadoop, Kubernetes, and other platform-like systems are complex to manage properly with good attention to security implies they should be delivered as cloud services rather than having everyone run their own. This enables K8s users to focus on apps while offloading management to specialists who can focus on running the services well.

If you operating at large enough scale you can bring the "cloud service" in-house.

scurvy 92 days ago [-]
One of the gating factors here is the both the speed of Kubernetes development (move fast and break all the things), and the terrible state of accompanying documentation.

If "they should be delivered as cloud services" is some sort of k8s apologist stance for its sorry state of maturity, then we got issues. OTOH, if it's "You shouldn't run it in house unless you have an army of people to read every new commit", that's wrong, too.

hodgesrm 92 days ago [-]
First of all let me be clear I'm not an expert in K8s and certainly not an apologist for bad software.

On the other hand there's a level of complexity in distributed systems that is impossible to avoid even in stable infrastructure. You have a design choice of trying to make the system as easy as possible to operate (at the cost of other features) vs. finding operating models that make it less of an issue.

Personally I would rather spend time futzing around with my applications that run on kubernetes vs. trying to run kubernetes itself. It would be sufficient if Kubernetes services were portable across a marketplace of providers so I could pick a place to run my applications.

hodgesrm 92 days ago [-]
Also as far as security is concerned it appears to me that a lot of people are deploying technology that they simply don't understand. This is not just a problem with Docker but with apps from ecosystems running on npm and pip.

You can build images securely with Docker but it requires building them yourself, using private registries, checking carefully for vulnerabilities, and testing. If you don't want to do this, pay somebody else to do it right. There's no free lunch.

kazen44 92 days ago [-]
How have containers solved maintaining production systems?

It's just moving the abstraction layer higher up the stack.

Also, who will design and build security for these systems? Or care about low-level performance?

A ton of dev's don't care about prod in my experience, and just want to ship shiny features.

Containers and VM's are not very different from a deployment or maintance standpoint. The deployment strategies used with containers could be done with (lightweight) VM's a decade ago. (heck, jails have been used for nearly 25 years)

Also, sysadmins have been automating stuff since forever. Without automation one inherently has a very unstable system.

johngalt 92 days ago [-]
No one is arguing that a sysadmin job should be protected. The article is more of a reminder that the sysadmin responsibilities don't disappear because we paper over them. Containers are a great tool, but they can trick people into thinking that certain things aren't a problem merely because they have been swept under the rug operationally.

With that in mind, I don't see sysadmins going anywhere soon. Every layer of abstraction is supposed to 'eliminate sysadmins', but inevitably it becomes yet another system that someone needs to audit and maintain.
