I don’t trust anything related to red hat

[–] Feliberto@programming.dev 8 points 1 year ago (2 children)

Genuine question here: why?

[–] Rearsays@lemmy.ml 9 points 1 year ago (1 children)

It’s just morally rough that they basically said they don’t get anything of benefit from contributing to open source despite really owing their start to it

[–] Feliberto@programming.dev 4 points 1 year ago

Thanks for the honest answer.

[–] ikidd@lemmy.world 2 points 1 year ago

Oh, well that's simple...

Dependencies within unrelated projects (ie, sharing a single database container for a few unrelated apps) is something that would be pretty handy, and is missing from compose.

Auto-updates are cool - but also dangerous... I think there's something in running watchtower manually like I have been - when something breaks straight after, I know the cause.

Couldn't you just create a compose file for a database separately?

[–] shadowbert@kbin.social 1 points 1 year ago

I don't really understand what you're suggesting. Having a seperate compose file for your database would "work", but you'd lack any of the dependency handling.

Honestly, this is kinda making me wanna redeploy a couple app stacks I have on a VPS. Hmm.

[–] thevoiceofra@mander.xyz -4 points 1 year ago (2 children)

Interesting. But what If I'm not using CoreOS? Also RedHat fucked up by using YAML for configuration.

[–] losttourist@kbin.social 12 points 1 year ago* (last edited 1 year ago) (1 children)

what if I'm not using CoreOS?

Podman runs on any distro (or more strictly: any distro that uses systemd). It's essentially a FOSS alternative to Docker.

...except I can run Docker anywhere. It's not tied to systemd. These quadlets seem like a very systemd-specific thing. Which is great if you're building everything around systemd but it's a niche.

[–] losttourist@kbin.social 11 points 1 year ago (1 children)

systemd [is] a niche

Maybe in the wider world of all the operating systems installed on all the computers, but for Linux-based computing it is, like it or not, near ubiquitous these days. And in particular for server systems (and this is, after all, /m/selfhosted), good luck finding something that isn't systemd-based unless you're deliberately choosing a BSD or aiming for a system which has ever-decreasing amounts of support available.

[–] lemmyvore@feddit.nl 2 points 1 year ago* (last edited 1 year ago)

This being selfhosted is exactly the reason I would've expected people to be aware there's more variety out there. systemd is not as ubiquitous as you make it sound.

Secondly, tying your containerization solution into your init system is a spectacularly bad idea. You could already tie containers into systemd units, quadlets just make it easier; but the best practice advice is to not do it at all. You have a restart policy built into docker/podman for a reason. Let the init system deal with podman/docker itself, and let podman/docker manage their containers.

Third, the article title is misleading; if anything it should say quadlets made them give up podman-compose, not docker-compose. There's no reason to reference docker in this article — unless you're doing it for the views.

[–] poVoq@slrpnk.net 3 points 1 year ago

It's built into Podman 4.x, so you can easily install it on any distro (with Systemd).
