Seems like podman-compose >= 1.1.0 requires a newer version of podman. The issue seems to be with the podman-compose build command forwarding environment variables to the podman build command. I suspect that the installed version of podman is too old and does not support this feature yet.

I am not aware if GH actions allows you to configure the version of podman installed, so you can either:

• downgrade the compose when you install it to something older than 1.1.0
• install a newer version of podman manually
