Setup Worker Node

Prepare the worker

Kamaji by default doesn't have worker provisioning flow. so you need to install the worker and it's depedencies manually (containerd, kubelet, kubeadm, etc) and join with Kamaji cluster via kubeadm join.

kubelet and kubeadm for worker node must be at the tenant's minor version (v1.34 for v1.34.12). the worker node also must be able to reach the LoadBalancer IP on both ports:

nc -zv <lb-ip> 6443    # kube-apiserver
nc -zv <lb-ip> 8132    # konnectivity-server

Join worker nodes

# generate a join command from the tenant control plane
kubeadm --kubeconfig test-control-plane.kubeconfig token create --print-join-command

# run the join command on the worker node
kubeadm join 192.168.1.201:6443 --token <redacted> --discovery-token-ca-cert-hash <redacted>

kubectl --kubeconfig test-control-plane.kubeconfig get nodes

(Worker prerequisites can be automated with Clastix's yaki script; for fully declarative nodes use the Cluster API provider.) (kamaji-generic)
