When MicroK8s updates, sites get taken offline

Microk8s is a Snap, so it gets updated automatically. Unfortunately this makes the site stop working, so I don't think we really want this.

Turning this off seems difficult: https://askubuntu.com/questions/1131182/how-can-i-disable-automatic-update-for-a-single-snap-in-ubuntu

We should probably move to something other than MicroK8s.
