Add one or more node pools to your cluster.

A node pool is a collection of nodes based on a node template. A node template defines the configuration of a node, like what operating system to use, number of CPUs and amount of memory. Each node pool must have one or more nodes roles assigned.

Notes:

• Each node role (i.e. etcd, Control Plane, and Worker) should be assigned to a distinct node pool. Although it is possible to assign multiple node roles to a node pool, this should not be done for production clusters.
• The recommended setup is to have a node pool with the etcd node role and a count of three, a node pool with the Control Plane node role and a count of at least two, and a node pool with the Worker node role and a count of at least two. Regarding the etcd node role, refer to the etcd Admin Guide.
