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