• 5.1 Modify kube config of federation cluster

Follow steps at 5. Deploying Federation Control Plane for federation master node. change the default kubernetes config values to make them unique. below steps for federation master node. change the default kubernetes config values to make them unique. 

By default, we have below kube config after k8s cluster installation:

ubuntu@kubefed-1:~$ kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: REDACTED
    server: https://10.147.113.131:6443
  name: kubernetes
contexts:
- context:
    cluster: kubernetes
    user: kubernetes-admin
  name: kubernetes-admin@kubernetes
current-context: kubernetes-admin@kubernetes
kind: Config
preferences: {}
users:
- name: kubernetes-admin
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
ubuntu@kubefed-1:~$

As we intend to use federation cluster as the "host cluster", we added "host" to cluster,user and context names to existing kube config so as to make these names unique.

The final result should config view on federation master node after making changes will look like something below:

 ubuntu@kubefedubuntu@kubefed-1:~$ kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: REDACTED
    server: https://10.147.113.131:6443
  name: kubernetes-host
contexts:
- context:
    cluster: kubernetes-host
    user: kubernetes-adminhost
  name: kubernetes-admin-host
current-context: kubernetes-admin-host
kind: Config
preferences: {}
users:
- name: kubernetes-adminhost
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
ubuntu@kubefed-1:~$
