备注：1. affinity:

        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: node-role.kubernetes.io/master
                operator: Exists

配置节点亲和性，requiredDuringSchedulingIgnoredDuringExecution 代表强制调度，调度pod到已存在的master role的节点（也就是master节点）

2.  污点容忍

      - key: node-role.kubernetes.io/master
        operator: Exists
        effect: NoSchedule
      - key: node.kubernetes.io/unschedulable
        operator: Exists
        effect: NoSchedule

容忍不可调度污点，以及master不可调度污点
