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.
Tbh it’s possible I messed something up, iirc the bridge network I was using wouldn’t work, and it seemed like it would only work in host mode, hence the belief that I needed to remap things. This was over a year ago, and tbh I didn’t try very hard to make it work.
