title: Kubelet certificate rotation - worker nodes
body: <p>I have been running K8s cluster(v1.13.5) for a year and the control plane certs and Kubelet certs are about to expire. I found a way to rotate all the control plane certs and I wanted to know how to rotate the Kubelet certs. Can someone help me to understand how to rotate the K certs for worker node and master (if needed)? This K8s cluster is deployed using Kubespray.</p>
