當(dāng)名稱空間kube-public 的configmap下面cluster-info 被誤刪除

• 1.尋找 一個(gè)cluster-info的模板

vim cluster-info.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: cluster-info
  namespace: kube-public
data:
  kubeconfig: |
    apiVersion: v1
    clusters:
    - cluster:
        certificate-authority-data: xxxxxxxxxxxx
        server: https://192.168.68.111:6443
      name: ""
    contexts: null
    current-context: ""
    kind: Config
    preferences: {}
    users: null

• 2.尋找certificate-authority-data
  在主節(jié)點(diǎn)的/etc/kubernetes/kubelet.conf里面有

• 3.將文件中的token填寫上去

apiVersion: v1
kind: ConfigMap
metadata:
  name: cluster-info
  namespace: kube-public
data:
  kubeconfig: |
    apiVersion: v1
    clusters:
    - cluster:
