kubernetes: 修改node 角色

kubernetes: 修改node 角色

新安装的kubernetes环境有时候node节点的 roles会缺失,我们可以手动添加上去

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

我们只需要给对应的节点打上合适的标签即可

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:~#

删除标签操作

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
