kubernetes： 修改node 角色

新安裝的kubernetes環境有時候node節點的 roles會缺失，我們可以手動添加上去

root@k8s-master:~# kubectl get nodes NAME STATUS ROLES AGE VERSION k8s-master Ready master 50d v1.16.7 k8s-node1 NotReady <none> 50d v1.16.7 k8s-node2 NotReady <none> 50d v1.16.7

我們只需要給對應的節點打上合適的標簽即可

kubectl label node k8s-node1 node-role.kubernetes.io/worker=worker

root@k8s-master:~# kubectl label node k8s-node1 node-role.kubernetes.io/worker=worker node/k8s-node1 labeled root@k8s-master:~# kubectl get nodes NAME STATUS ROLES AGE VERSION k8s-master Ready master 50d v1.16.7 k8s-node1 NotReady worker 50d v1.16.7 k8s-node2 NotReady <none> 50d v1.16.7 root@k8s-master:~#

刪除標簽操作

kubectl label nodes  k8s-node1 node-role.kubernetes.io/worker-

[root@k8s-master ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
k8s-node1 Ready <none> 37d v1.18.3
k8s-node2 Ready worker 37d v1.18.3
