Proxmox - Guests (VMs and Containers) - Docker - Methods for running Docker containers in Proxmox

Methods for running Docker containers in Proxmox.

Docker running on Proxmox itself: Not very secure. Can impact the Proxmox host.
Docker in LXC privileged container: Can be a security risk.
Docker in LXC unprivileged container: More secure than a privileged container. Can give compatibility problems, permissions challenges.
Docker running in a VM: Most secure option. Slightly lower performance vs using a container.
