 systemctl --user 

first you need to create the system unit this looks at the properties of the already running container. THese are stored in /home/user/.config/systemd/user/ command is

podman generate systemd --name container_name --files --new

you need to create the directory and then CD into it before running the command. Generate the files and start it as a fresh container
