build containers to confirm that your build steps all work ok, so Podman + buildah, then you might want to
... push them to a repository to collaborate with a colleague without setting up CI/CD, so Podman + Buildah + skopeo.
Then you might want to execute the containers to test to see whether your code is running ok....
the point I was making didn't relate to running containers on servers where typically things like CI/CD will be part of the process, but to new developers and devops people getting started with containers.
