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.
