[Podman] Expoising ports automatically

Hi, Newbie question... I'm playing out with rootless container based on: docker.io/library/mysql If I run this image (without specifying ports or volumes) it will create a volume automatically. I did "inspect" the image and I see the volume is defined there. I also noticed the ExposedPorts as well but podman didn't create theses. Why would it create the volume but not expose the ports (if they're available and above 1024)? Thanks, Jorge
