Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster. Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
$ kubectl get nodes NAME STATUS ROLES AGE VERSION node1 Ready control-plane 9m26s v1.30.3 node2 Ready <none> 4m1s v1.30.3 node3 Ready <none> 4m2s v1.30.3
