There are still edge cases, but things have improved rapidly the last year or two, to the point that most docker-compose.yaml files can be run unmodified with podman-compose.

I have however moved away from compose in favor of running containers and pods as systemd services, which I really like. If you want to try it, make sure your distro has a reasonably new version of Podman, at least v4.4 ot newer. Debian stable has an older version, so I had to use the testing repos to get quadlets working.

I'm no expert, but as far as I can tell yes. It also seems a bit easier to have a rootless setup.

It depends on what you do with Docker. Podman can replace many of the core docker features, but does not ship with a Docker Desktop app (there may be one available). Also, last I checked, there were differences in the docker build command.

That being said, I'm using podman at home and work, doing development things and building images must fine. My final images are built in a pipeline with actual Docker, though.

I jumped ship from Docker (like the metaphor?) when they started clamping down on unregistered users and changed the corporate license. It's my personal middle finger to them.

I, too, need to know..
