必须容忍 node 上的所有污点才可能调度

    pod.spec.tolerations <[]Object>

    1. tolerations:
    2. - key: "k1"
    3. operator: "Equal"
    4. value: "v1"
    5. effect: "NoSchedule"
    6. - key: "k2"
    7. operator: "Equal"
    8. value: "v2"
    9. effect: "NoExecute"
    10. tolerationSeconds: 300

    operator 为 Exists 将会忽略 value 对应的值 , 默认是 Equal

    tolerations:
    - key : “xxx”
    operatpr: “Exists” # 只要有这个 key的污点都容忍

    tolerations:
    - operatpr: “Exists” # 所有污点都容忍

    tolerationSeconds 必须配合 NoExecute
    不指定 tolerationSeconds ,容忍此污点的 pod 不驱逐
    指定 tolerationSeconds, 到了时间驱逐 pod
