I personally like the verbose notation for docker volumes in docker compose files, where source and target are separate attributes in the YAML file. Not all munged into one long string, and unable to specify the type of mount explicitly. But that notation does not support stating the :z or :Z. I am running a Debian most of the time to develop and had no issue with the docker bind mounts, but on Fedora Selinux messed things up and I would get strange permission denied errors in the container for bind mounted config files. So I would have to change my docker compose file just for Fedora and Selinux. I think I even tried it with one of z: or Z:, but still Selinux interfered. At some point I had the choice of burning many more hours into configuring Selinux, disable Selinux, or reinstall docker as root. Since the Fedora OS is merely a VM, I chose to install Docker as root.

My point is: If figuring things out with podman is similar to my experience, I understand why people don't want to do that. Do they have a definitive page dedicated to setting up Selinux for podman, that is well maintained and guaranteed to solve all Selinux issues, and allows me to use bind mounts with readonly permission?
