Because these are pis, edit the following and add: cgroup_memory=1 cgroup_enable=memory
sudo nano /boot/cmdline.txt

sudo nano /etc/dhcpcd.conf

interface eth0
static ip_address=10.1.50.0/24

sudo apt update && sudo apt upgrade -y
Install dependencies needed
sudo apt install nfs-common open-iscsi -y

sudo nano /etc/hosts
10.1.50.21 pi-k8s-01
10.1.50.22 pi-k8s-02
10.1.50.23 pi-k8s-03
10.1.50.24 pi-k8s-04
10.1.50.25 pi-k8s-05
10.1.50.26 pi-k8s-06
Reboot the pis
sudo reboot
