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 image, number of CPUs and amount of RAM. Each Node Pool can have one or more Nodes Roles associated with it.

Notes:

• After you create a Node Template, it will be saved and you will be able to re-use it in additional Node Pools.
• Each Node Role (i.e. etcd, Control Plane, and Worker) must be fulfilled. Although it is possible to apply multiple Node Roles to a Node Pool, this is not recommended.
• 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.
