So podman-compose is really not where it’s at. This is coming from a long time ex-user. It’s a simple project with 117 open issues and 37 pull requests going back to 2019 (very few/no comments). There are many missing features and incompatibilities. I’m an ex-user because as of podman v2.2 there’s support to emulate the Docker socket which allows one to use Docker-compose.
