Well I use ansible's podman module to setup/configure my containers and then use it to generate systemd from that.

Before that I used Makefiles.

Youre supposted to have podman generate systemd for you. With the recent update, your systemd unit will have a [Container] section which will be easy to configure manually if you want.
