Part 7 – Setting up kubelet and kube-proxy on Worker Nodes

In this part of the “RKE2 the Hard Way” training series, we will configure kubelet to register with the Kubernetes API server and set up kube-proxy on our nodes. We already installed containerd and kubelet in Part 3, but now we need to finalize their configuration to connect to our Kubernetes control plane.

kubelet is the primary node agent that runs on each node. It ensures containers are running in a Pod and healthy.
kube-proxy maintains network rules on nodes. These network rules allow network communication to your Pods from inside or outside of your cluster.

✅ Note: In our setup, all nodes (node01, node02, node03) are both control plane and worker nodes. This is common for smaller clusters and provides high availability without needing separate worker nodes.

Kube-proxy is responsible for implementing the Kubernetes Service concept, providing network proxying and load balancing. This deep dive explores its architecture, proxy modes, and internal workings.
