GCP: Deploy Control Plane Nodes via MachineSet

Goal:

Control plane nodes in the cluster can be scaled up or down, lost and recovered, with no more importance or special procedure than that of a data plane node.

Problem:

There is a lengthy special procedure to recover from a failed control plane node (or majority of nodes) and to add new control plane nodes.

Why is this important:

• Increased operational simplicity and scale flexibility of the cluster’s control plane deployment.

• Core
