Part 6 – Setting up kube-controller-manager and kube-scheduler as Static Pods

In this part of the “RKE2 the Hard Way” training series, we will set up the Kubernetes Controller Manager (kube-controller-manager) and Scheduler (kube-scheduler) as static pods managed by kubelet on each of our nodes.

The Controller Manager runs controller processes that regulate the state of the cluster (such as replication controllers, node controllers, and service account controllers)
The Scheduler is responsible for watching for newly created pods and assigning them to nodes

Using static pods for these components is a key design principle in RKE2, just like we did for etcd and kube-apiserver. This approach ensures high availability and automatic recovery in case of failures.
