kubernetes对node添加Label

打标签

kubectl label nodes <node-name> <label-key>=<label-value> 

kubectl label node  node62 role=haproxy-ingress

删除标签注意后的扛-

kubectl label nodes <node-name> <label-key>-

[root@master66 haproxy]# kubectl label nodes node62 role-
node/node62 labeled
[root@master66 haproxy]# kubectl label nodes node63 role-
node/node63 labeled

修改Label的值
语法: 需要加上–overwrite参数

kubectl label nodes <node-name> <label-key>=<label-value> --overwrite
