Installing microk8s in an LXC container (i.e.: proxmox)

This is an roundition of https://gist.github.com/acj/3cb5674670e6145fa4f355b3239165c7 which got a bit messy

1. Create a LXC container through the Proxmox web interface (ie.: ubuntu.23-10-lts)
   • untick "unpriviledged" container
   • in memory, set swap to 1024
   • set mem to at least 4096
   • in network, make sure you assign static ip-adress to the container
   • create container but don't start it.
   • after create, go to options and tick "fuse" and "nesting"
   • in /etc/pve/lxc/*.conf add these lines:
     • lxc.apparmor.profile: unconfined
     • lxc.cap.drop:
     • lxc.mount.auto: proc:rw sys:rw
     • lxc.mount.entry: /dev/fuse dev/fuse none bind,create=file 0 0
     • lxc.mount.entry: /sys/kernel/security sys/kernel/security none bind,create=file 0 0
   • run container
2. Setup microk8s
   • inside container start crontab -e command
     • add line "@reboot ln -s /dev/console /dev/kmsg"
   • install required packages
     • apt update && apt upgrade -y && apt install snapd squashfuse fuse sudo -y
   • reboot container
   • install microk8s
     • snap install microk8s --classic

apparmor_parser --add /var/lib/snapd/apparmor/profiles/snap.microk8s.*
microk8s start

fixes a problem, when micok8s refuses to boot:

Please make sure that the snapd.apparmor service is enabled and started```
