Kubernetes Node

Configuration for a basic node in the cluster.

Sample Document

Here is a sample document:

schema: promenade/KubernetesNode/v1
metadata:
  schema: metadata/Document/v1
  name: n1
  layeringDefinition:
    abstract: false
    layer: site
data:
  hostname: n1
  ip: 192.168.77.11
  join_ip: 192.168.77.10
  labels:
    static:
      - node-role.kubernetes.io/master=
    dynamic:
      - calico-etcd=enabled
      - kubernetes-apiserver=enabled
      - kubernetes-controller-manager=enabled
      - kubernetes-etcd=enabled
      - kubernetes-scheduler=enabled
      - ucp-control-plane=enabled

Host Information

Essential host-specific information is specified in this document, including the hostname, ip, and join_ip.

The join_ip is used to specify which host should be used when adding a node to the cluster.

Labels

Kubernetes labels can be specified under the labels key in two ways:

  1. Via the static key, which is a list of labels to be applied immediately when the kubelet process starts.
  2. Via the dynamic key, which is a list of labels to be applied after the node is marked as Ready by Kubernetes.
