Setup Container to Run as Systemd Service (Rootless Mode)
---------------------------------------------------------------------------------

Create config directory in home to store systemd files
	mkdir ~/.config/systemd/user

Launch the container
	podman run -d --name test_container -p 80:8080 <image>

Generate systemd unit files
	podman generate systemd --name test_container --files --new

Inspect new systemd unit file
	less ~/.config/systemd/user/test_container.service

Enable linger to allow for persistent non-root systemd containers to run
	loginctl enable-linger
	loginctl show-user cloud_user | grep linger
	"Linger=yes"

Reload daemon files (at the user level)
	systemctl --user daemon-reload

Enable new container service (at the user level)
	systemctl --user enable  --now test_container.service
