Your Kubernetes control-plane has initialized successfully!<\/p>\n

To start using your cluster, you need to run the following as a regular user:<\/p>\n

mkdir -p $HOME\/.kube
\n sudo cp -i \/etc\/kubernetes\/admin.conf $HOME\/.kube\/config
\n sudo chown $(id -u):$(id -g) $HOME\/.kube\/config<\/p>\n

You should now deploy a pod network to the cluster.
\nRun “kubectl apply -f [podnetwork].yaml” with one of the options listed at:
\n https:\/\/kubernetes.io\/docs\/concepts\/cluster-administration\/addons\/<\/p>\n

Then you can join any number of worker nodes by running the following on each as root:<\/p>\n
