Sure, docker-compose is great, but could we get similar functionality using just the tools that are built into CoreOS? Can we get automatic updates, too? Yes we can! 📦
…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.
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.
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.
Podman runs on any distro (or more strictly: any distro that uses systemd). It’s essentially a FOSS alternative to Docker.
