Today’s K3s objective: OS Setup

Assign IP addresses in UniFi. I don’t like assigning IP addresses anywhere other than at the router level so I won’t be doing this directly on the pi’s.

Configure each pi with timezone, hostname, password.

Append the following to cmdline.txt

group_enable=cpuset cgroup_enable=memory cgroup_memory=1

Modify /etc/hosts

10.0.20.160 cube01 cube01.local
10.0.20.161 cube02 cube02.local
10.0.20.162 cube03 cube03.local
10.0.20.163 cube04 cube04.local

Finally, install iptables

apt -y install iptables

Next I’ll be performing the Kubernetes installation.
