Honestly, fuck Ansible.
It's the dialup of automation tools. It was probably amazing 10 years ago.
It's YAML is awful, it scales terribly, it's so fucking slow at literally everything, it gives people who have no clue what they're doing a false sense of confidence.
The number of times I've seen app teams waste the time of support groups and engineers because something went wrong and they didn't have the knowledge to know why and need to waste so many man hours having other people solve it for them. I (the engineer) was added to a chat that had 15 people in it because they, after running ansible, saw errors in their server... So clearly there was a problem with the server... At no point did they question there Ansible job.
Of the various tools I've used, I prefer Salt. The YAML is slightly less ass and it's so much faster while also seeming to scaling better too. It by no means is perfect.
Honestly, fuck Ansible.
It’s the dialup of automation tools. It was probably amazing 10 years ago.
It's actually on par with 20-year-old tech. There's nothing it's doing that we weren't doing back then already in the enterprise space. And, in so many cases where Ansible's unable to respond well to changes to the system, it ends up not being on par with 20-yer-old tech.
Salt is better as it's one generation newer, aka last-gen. Puppet, salt, chef/cinc, all the same generation, and we get single source of truth and fast operation de
Current-gen is mgmtconfig, and from it we get instant/constant converging event-driven code. If you like ansible, you're gonna love sale or cinc. If you love salt or puppet, mgmtconfig will blow your mind clean out the back of your head.
100 servers? 5000? Ansible don't care
Sub-second convergence of thousands of servers. Files managed so hard you can't manually mod them as they revert immediately and it's an actual race to try and mod a file to use it, since it's hooked into inotify and friends.
James even put in a YAML-ish DSL for the crayola crew who haven't learned Go yet. :-P
"crayola crew" - amen brother
mgmtconfig
Never heard of that, will be looking into it
You had me at “fuck Ansible”.
I also appreciate the alternative suggestion. No terraform love?
Terraform and Ansible do different things, they do have overlapping features, but ultimately they're meant to do different things. I use them both at my current job with Terraform running Ansible
No terraform love
Terraform 0.12 was awesome. It had no supply-chain sploit risk, ran well, accepted add-ons easily, and was very powerful.
Then they got a registry for people to attack, an umbilical to operation that ubisoft would envy.
I've been unable to get anything newer approved so far, because of the risk . Sure, you firewall off the box running CI, but often it needs to get out to the world, and suddenly it's a WAF on top of everything, and it's a real mess ... which they can eliminate by killing terraform usage altogether. And I don't wanna see that, as while tf's dsl is pretty weird it's the least-worst tool out there.
THANK YOU FOR THE SUMMARY, BROTHER. I'M GONNA TRY IT OUT AFTER I CRANK MY HOG. AROOOOOO!
I have to say, the resurgence of this energy in the last whenever has been refreshing. Can't we all just crank our hogs?
Anyone that says yaml is readable is psychotic. It's literally objectively not readable because a random white space character can break the entire thing and that's by definition not readable I can't see whether there's a white space or not without explicitly setting that up in an editor
The scandinavian country codes, as understood by yaml:
- se
- false
- dk
That's what ansible-lint is for.
Since when is YAML readable and clean?
Small yaml files are, big complex ones are a nightmare.
"Keep it simple" says the project that decided it would be great to program in YAML...
I've tried using it to manage a few home servers and parameterizing anything was painful and boilerplate-ridden
I seem to remember having the same trouble, maybe with hiding vars from logs?
uses yaml for scripting so it's clean and readable.
Eh....
I guess yaml is fine.
I hate the significance of whitespace, and the fact that I cannot find any editor that can auto-format. Which are both related, I guess: there is no way to know a yaml document is actually correctly formatted without knowing the intended schema.Whereas JSON doesn't have this ambiguity. But JSON has it's own drawbacks.
YAML is fine as a configuration language and ok data input language.
YAML is absolutely cursed as a programming language. As in Ansible has created a really shitty programming language inside of YAML. Should be burned with fire.
I guess it's like HTML if it tried to also adopt it's own scripting language. Whereas JS interacts with the HTML DOM. Sure, it has quirks, but essentially modified a config.
I've never found a nice way writing YAML with variables and configurability.
Trying to use yaml to natively describe how a yaml config should be produced is broken. It diverges from the underlying schema, and (because it's.yaml) isn't distinguishable from any other yaml.
Things like helm treat yaml as a template. And I don't think language servers & tooling are up to scratch yet (happy to be corrected). So basic yaml formatters shit the bed.Yaml is a computer readable config file that tries to be human readable, and fails at being actually useful.
Why projects try and make it useful, I will never understand.
I honestly think generating yaml from something like python would be a million times easier.
But then tools like ansible adopt yaml to essentially be a scripting language. As opposed to creating an actually decent solution that uses both python (to generate) and yaml (to apply).
Or whatever language.
I kinda like YAML for simple configuration files, but the YAML spec is borderline insane.

And don't get me started with ansible, it never works the way I think it should and almost every playbook or role I write is a pain to get right. When it works, it's a really nice tool and I couldn't manage my homelab as efficiently without Ansible, but it frustrated the hell out of me way too often.
I feel I spend more time iterating yaml.
There isn't any tooling that actually helps you write it.I feel like there is a gap in the market for a solution that uses typescript, typed python or some other type-able scripting language, which then generates the yaml files.
A language that has language servers, intellisense, all the modern dev tools. Schemas are provided as simple type descriptors. And whatever script you write then produces the correct result.
Some sort of framework on top of that to provide an opinionated workflow, and some tooling to lint/validate/produce.
And the result is yaml files which can be checked/diffed against in-place config, and version controlled for consistency.
Protip: you can actually just write your ansible (or any yaml really( as JSON.
Are you looking for an editor that can format YAML out-of-the-box or with plugins? In my experience, most editors only support a small number of formats out of the box and extend that functionality with plugins. I have yet to find a solid, production editor without a decent YAML formatter. If you’re using one of the common commercial ones, Red Hat maintains many that work explicitly for Ansible.
I hate anything that uses python or depends on whitespace in it's code. Nothing but fucking problems. You know what's hard to see an extra space in a line of code. A missing semicolon is so much easier to find.
i keep telling myself what a timesaver ansible is, while at the same time my simple scripts got abstracted and puzzled into more files, much harder to quickly read and understand them and after hours of frustration, ansible actually works. there may be multiple minutes of delay between my tasks wasting time like hell but it works (as in not randomly fails to connect). except when it doesn’t. there still is a playbook where the host cannot be reached and i keep on failing to understand why as everything appears to be the same and looks correct. there will be more hours wasted.
The higher abstraction level is the price you pay for idempotency!
Hello? Its me, NixOS.
NixOS : no dudes, its not raw screeching madness, its great. Just great. So great. Please read these 17 guides that are outdated more every minute to get started. Also, dont read that guide. We don't do that anymore, but there is no way for me to explain why unless you already know.
Ive tried NixOS three times now, and it hasn't took. Has anyone written a sane guide to the current iteration yet?
Listen. The more painful it is up front, the better you'll feel once you get it.
After a suspicious-looking guide I nearly started with, and the NoxOS split drama, and having homemanager bork my login in a test setup, I wonder if next time I'll try GUIX.
Yeah, guix started as a nix fork with scheme, we all dancing at the same party.
I've been using Ansible for almost 10 years now and one thing I learned is to keep things simple, most issues I had with Ansible in the past were due to me taking the wrong approach to problem solving. In way, it forced me to not overcomplicate things.
I'm not the biggest fan of it, but I do prefer it over other IaCs.
edit: tbh my biggest issue with Ansible is other people who ask me "why not wrtie a bash script instead?"
Finally, KISS enforced software
Last time I checked on ansible, it was a sysadmin complaining that he could just do everything better with vanilla bash scripts and that redhat keeps riding it because every company keeps asking for ansible experience, even if it's now a dated product.
And just personally, declarative anything seems to defeat it's own purpose any time you want to do something non standard, which comes up more often than you'd think.
You forgot that it can run without ssh set up, by installing ansible on the machines and letting them poll for changes.
uses vanilla ssh
Clearly you haven't tried automation of network devices because it constantly bitches about missing ansible-pylibssh and falls back to Paramiko
I finally understand Ansible.
WASTHATSOFUCKINGHARD?!?!!
I love this meme format!
Also completely parses your whole goddamn secrets file multiple times per run, so if you need to change a single server, make sure you have time.
Feels insecure
The enemy gate is down
Wtf is SSH and why should I care?
SSH is a network protocol for making secure connections, allowing remote access to various systems. As for why you should care, if you didn't know what SSH was, then you probably shouldn't care since you aren't the target audience. It's fringe knowledge for me too.
