I'm one of those million as I installed it last week and I've been impressed with it and podman as a whole.
Just today I piped a cross-platform image from my M2 Mac running podman to an amd64 Linux server running Docker today and it just worked. So far it's been a viable alternative to begging for a Docker license.
I have the CLI installed and use it quite often for managing containers and as a replacement for docker-compose. Can anyone comment on whether docker is better? I’ve never had any issues with podman and use it since it’s installed by default but curious why more people use docker.
I'd guess the short answer is "inertia," and that word applies to the whole ecosystem: tutorials, existing infrastructure, chatgpt summaries, stackoverflow questions (maybe that one is redundant now, heh), etc, etc
We run 100% containerd in production because I previously had the docker daemon lock up which nukes every container on the host, and never installed docker ever again on any production instance. But, I have no interest in babysitting every junior (or, ahem, some senior ones) engineer to mentally translate the docker commands to either podman or nerdctl. I am aware some folks allege $(alias docker=podman) works for them, and good for you, but that's not been my experience
