Podman and the Unwanted Daemon

Podman ought to be the hero of a children's story. I seem to remember him making a brief appearance in The Garden Gang as the father of Percival Pea.

But if you're working with linux containers, podman does it without a daemon.

Podman and Buildah vs Docker

There are plenty of articles pitting docker against podman and buildah - the best I have seen is this RedHat blog.

Here's a quick summary:

• podman operates on containers directly (and buildah on images), while docker routes its commands (run, build) through a daemon.
• Meaning that buildah images are user-local and podmanaged containers run with the permissions of the user.
• Dockerfiles and built images are compatible. In fact podman run hello-world uses the standard docker image to print a description of how docker - and not podman - works.
• podman cli is completely compatible with docker (but extends it - e.g. podman rmi --all)
