Podman-compose has a history of being buggy, don’t support running one service at the time, command execution in the container etc. (I’ve been stuck with it for a long time) It also don’t behave exactly like docker-compose, which makes it annoying when the entire team don’t use the same stack.

With that said, podman now support docker-compose. Seems to still require to be privileged for volume mounting on Linux, but haven’t looked too much into it.

Podman-compose used to be a wrapper Python script around podman itself as far as I know, it wasn't a proper docker-compose implementation. So yes, it was not ideal.

What is proper docker compose implementation? If I recall correctly original compose itself was a pile of python scripts reimplementing a lot of stuff docker daemon did

I remember Aanand chatting about it, it was originally called fig https://github.com/aanand/fig and it was python scripts.

My primary issue w/ Docker on Windows is that a simple Windows update can ruin all your containers. I know this is not a Docker issue but a big issue in general; hence why I am looking for alternatives. Do podman coming to Windows?

it works great for me on wsl2 using Ubuntu 21.04

Denver coder, what did you see!!

The number of issues to get started with podman are currently too many like author mentioned. I really wish podman to compete with docker, but its not there yet (ignoring all the complex integrations with Kubernetes)

Can I use it to run integration tests with test containers? Is some one using it? (On Mac)

I don't see why you couldn't. One thing that I did not realize initially was that bind mounts do not work nicely out of the box on mac without mounting via sshfs. https://github.com/containers/podman/issues/8016
