Podman pods & containers for devel and testing.

• Copy .pod, .container, .build and .volume files to /etc/containers/systemd/

• All of the volumes here are bind-mounted, hence you need to create the directory first
• Example: In postgres.volume, Device=/var/opt/containers/postgres means /var/opt/containers/postgres dir should be created first

• Reload systemd sudo systemctl daemon-reload
• Systemd will generate services from the installed files
• Run container using systemctl start, e.g. for postgres.container, run systemctl start postgres.service

• Supports podman auto-update
• Easier to maintain as quadlet files (podman-compose sucks)
