This is my biggest gripe. If you're using docker-compose.yml on a team that mostly uses docker, you can't use use that same docker-compose.yml with rootless podman. Any volume mounts that need to be writable (like the app, or databases) need to have `:X` or `:x` as a suffix, or podman won't set the SELinux label correctly to make it writable. But if you add those, docker blows up because it doesn't understand them.
