Node

A node resource (Node) represents a node running Calico Enterprise. When adding a host to a Calico Enterprise cluster, a node resource needs to be created which contains the configuration for the cnx-node instance running on the host.

When starting a cnx-node instance, the name supplied to the instance should match the name configured in the Node resource.

By default, starting a cnx-node instance will automatically create a node resource using the hostname of the compute host.

This resource is not supported in kubectl.
