I use `podman` by preference when working with Dockerfiles, as I find its rootless mode of operation less invasive. It has different defaults in handling short names of images, which interestingly work for node images, but not Ruby. However, while looking into this, I saw the config file in `/etc/containers/registries.conf` advises use of fully qualified image names, so I adjust node to use full qualification as well.
