Installing microk8s in an LXC container

I wanted to run Microk8s on a Proxmox 6 host inside of an LXC container. These are my notes from the journey.

1. Create a privileged LXC container through the Proxmox web interface

• Enable nesting and FUSE
  • In Proxmox UI, select container, then Options > Features > Check nesting and FUSE boxes

2. SSH into the Proxmox host and edit the container's config in /etc/pve/lxc/.conf
   • Add the following lines lxc.apparmor.profile: unconfined

On the host

Ensure these modules are loaded

cat /proc/sys/net/bridge/bridge-nf-call-iptables

Disable swap

sysctl vm.swappiness=0
swapoff -a
