无法访问异味节点上的kubernetes集群服务

Question

我试图通过定义显式公差来在污点节点上部署Alertmanager服务。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: alertmanager
  namespace: monitoring
spec:
  replicas: 1
  selector:
    matchLabels:
      app: alertmanager
  template:
    metadata:
      name: alertmanager
      labels:
        app: alertmanager
    spec:
      tolerations:
      - key: "prometheusnew"
        operator: "Equal"
        value: "false"
        effect: "NoExecute"
      affinity:
        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: placement_affinity
                operator: In
                values:
                - prometheusnew
      containers:
      - name: alertmanager
        image: prom/alertmanager:v0.15.3
        args:
          - '--config.file=/etc/alertmanager/config.yml'
          - '--storage.path=/alertmanager'
        ports:
        - name: alertmanager
          containerPort: 9093
        volumeMounts:
        - name: config-volume
          mountPath: /etc/alertmanager
        - name: alertmanager
          mountPath: /alertmanager
      volumes:
      - name: config-volume
        configMap:
          name: alertmanager
      - name: alertmanager
        emptyDir: {}

可以从同一节点访问群集ip 172.30.148.104，但是不能从其他节点或不同节点中的pod来访问pod和服务ip。

NAME           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
alertmanager   ClusterIP   172.30.148.104   <none>        9093/TCP   20m

Pod运行良好，如果部署时没有污染，则可以正常工作。 感谢任何帮助，谢谢。
