The original EverQuest theme song was mine. Captured the epic wide-eyed wonder of going on an adventure perfectly.

Hey there, for a very simple start there’s the compose.yaml file at the bottom of my comment here.

This sounds like something on your end as I get cached builds every time, rootlessly even. Podman also supports cache mounts.

Check my comment history for an example of a simple bind mount compose.yaml I use for developing a small Python project. It’s exactly the same as Docker Compose (since Podman Compose follows the Compose spec) but if you’re just getting started, it might be a good skeleton to build on.

There’s real usability benefits too. I’ve collected some anecdotes from Reddit:

Rootless podman is my first choice for using containers now, it works fantastically well in my experience. It’s so much nicer to have all my container related stuff like volumes, configs, the control socket, etc. in my home directory and standard user paths vs. scattered all over the system. Permission issues with bind mounts just totally disappear when you go rootless. It’s so much easier and better than the root privileged daemon.

and,

If you are on Linux, there is the fantastic podman option “–userns keep-id” which will make sure the uid inside+the container is the same as your current user uid.+

and,

Yeah in my experience with rootless you don’t need to worry about UID shenanigans anymore. Containers can do stuff as root (from their perspective at least) all they want but any files you bind mount into the container are still just owned/modified by your user account on the host system (not a root user bleeding through from the container).

finally,

The permissions (rwx) don’t change, but the uid/gid is mapped. E.g. uid 0 is the running user outside the container, by uid 1 will be mapped to 100000 (configurable), and say 5000 inside the container is mapped to 105000. I don’t remember the exact mapping but it works roughly like that.

It should be harder to support Docker, which hasn’t released a new open source product since before Docker Desktop, which is also proprietary. Podman Desktop? OSS. It’d be hard to name a product Red Hat supports that isn’t OSS.

For what it’s worth, I just wrote up a compose.yaml file as I’d write it for Docker Compose and it just worked. See the bottom of my comment on this GitHub issue for an example. I think the team’s intention is for it to transparently support whatever you’d write for a standard Compose file but of course we don’t have things like the brand new Docker watch. They do point to the Compose spec in the Podman Compose README. Bind mounts are good enough for me, thus far.
