污点

查看节点上的污点

# kubectl describe nodes 节点名 | grep Taint
kubectl describe nodes node-name | grep Taint

结果示例：

Taints:             node-role.kubernetes.io/control-plane:NoSchedule

删除污点：

#kubectl taint nodes 节点名 node-role.kubernetes.io/control-plane:NoSchedule-
kubectl taint nodes node-name node-role.kubernetes.io/control-plane:NoSchedule-

占用 设置污点

# nginx 专用节点
kubectl taint nodes s4 lock=nginx:NoSchedule
# kubectl taint nodes s4 lock=nginx:NoSchedule-

容忍污点 - 键值匹配

tolerations:
- key: "lock"
  operator: "Equal"
  value: "nginx"
  effect: "NoSchedule"

容忍污点 - key 存在

tolerations:
- key: "lock"
  operator: "Exists"
  effect: "NoSchedule"
