Raspberry Pi 4 (4GB) Cluster

Random notes from setting up my cluster, I'll clean this up later.

Ubuntu 19.10 Imaged with the official Raspberry Pi imaging tool Configured wifi (dhcp) Configured eth0 with static IP (via Router, NIC MAC is tied to IP lease) Generated and Added SSH keys Disabled password sign-in Installed microk8s (x4) Enabled dns and metrics-server on master

After installing microk8s via snap, all nodes (master included) were stuck in NotReady status.

what actually worked is editing /boot/firmware/nobtcmd.txt, appending cgroup_enable=memory cgroup_memory=1. and rebooting.
