给 master 节点打上标签：

1. 给 master 节点打上 master 标签

kubectl label node k8s-master01 node-role.kubernetes.io/master=''
kubectl label node k8s-master02 node-role.kubernetes.io/master=''
kubectl label node k8s-master03 node-role.kubernetes.io/master=''

2. 给 master 节点打上污点不可调度

kubectl taint nodes k8s-master01 master-node.example.com/dedicated=:NoSchedule
kubectl taint nodes k8s-master02 master-node.example.com/dedicated=:NoSchedule
kubectl taint nodes k8s-master03 master-node.example.com/dedicated=:NoSchedule

给工作节点打上 worker 标签：

1. 给 node 节点打上 worker 标签

kubectl label nodes k8s-worker01 node-role.kubernetes.io/worker=''  
kubectl label nodes k8s-worker02 node-role.kubernetes.io/worker=''
