Installing Podman on Proxmox is rather straight forward. The initial idea for how to do this came from a post on the Serve the Home (STH) blog: Create the Ultimate Virtualization and Container Setup (KVM, LXC, Docker) with Management GUIs. In that article STH uses Docker and provides a Portainer GUI. In this example the Portainer GUI is going to be omitted and use Podman instead of Docker. The daemonless part of Podman is the real selling point.
