I am moving from docker to podman and selinux because I thought that podman is more secure and hence, the future. I thought the transition will be somewhat seamless. I even prepaired containers but once I migrated I still ran into issues.
minor issue: it’s podman-compose instead of podman compose. The hyphen feels like a step back because we moved from docker-compose to docker compose. But thT’s not a real issue.
podman does not autostart containers after boot. You have to manually start them, or write a start script. Or create a systemd unit for each of them.
Spinning up fresh services works most of the time but using old services that worked great with docker are a pain. I am wasting minutes after minutes because I struggle with permissions and other weird issues.
podman can’t use lower number ports such that you have to map the ports outside of the machine and forward them properly.
Documentation and tutorials are “all” for docker. Github issues are “all” for docker. There isn’t a lot of information floating around.
I’m still not done and I really wonder why I should move forward and not go back to docker. Painful experience so far. https://linuxhandbook.com/docker-vs-podman/ and following pages helped me a lot to get rid of my frustration with podman.
Definitely not necessary. If that was the case, it wouldn’t live up to it’s claims of being a transparent Docker replacement at all. I think you do need to use systemd if you want to go full rootless, but I haven’t tried it enough to make a solid call on that.
But yeah, with the above steps, I’ve moved seamlessly over to Podman for my self hosting stack and I’ve never looked back. It’s also great because I can take literally any Docker Compose I find on the Internet and it will most likely just work.
