<p>I'm deploying K8s to the Oracle Cloud Infrastructure where while I can make sure that the public internet facing IP stays static even when the instances are restarted. But for some reason the private IP of the instances always changes. Which brings me to the question - can Kubernetes work with nodes who's IP changes after restarts?</p>

<p>This could be quite a noob question but I did try to read up online and I couldn't find a conclusive answer.</p>

<p>Yes, kubernetes can handle that case easily, and on OCI it works just fine.  The individual worker nodes will (using the kubelet on that host) call to the master IP, which we would recommend using a load balancer to front to achieve a static IP and allow you to change, scale, and otherwise adjust your master kubernetes control plane nodes as you wish, without disrupting the workers.</p>

<p>You can get a pretty slick setup currently with the terraform tooling for kubernetes that is published here:</p>
