Initial Dependencies

Install Raspberry Pi OS 64bit Lite.

Add the following to the end of the line in /boot/firmware/cmdline.txt

cgroup_memory=1 cgroup_enable=memory

Reboot

Install k3s

For latest supported version for Rancher

curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.30.5+k3s1 sh -

Else for latest version (You won't be able to install Rancher with this version)

curl -sfL https://get.k3s.io | sh -

Install Helm

apt install git -y
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

Install Cert Manager

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.15.3/cert-manager.yaml

Install Rancher

kubectl create namespace cattle-system

helm repo add rancher-latest https://releases.rancher.com/server-charts/latest

helm repo update

Note you'll need to change the hostname and password below. The replicas is ok at -1 as it will just spin up a rancher instance for each k3s node you have.

helm install rancher rancher-latest/rancher \
  --namespace cattle-system \
  --set hostname=rancher.lan \
  --set bootstrapPassword=password \
  --set replicas=-1
