0/2个节点可用：1个节点未找到可用的持久卷来绑定，1个节点有pod不能忍受的污点

Question

我在多个节点中设置了一个k8s。但是，当我尝试创建简单的PostgreSQL时，PersistentVolume无法成功创建。

StorageClass

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

StatefulSet是：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: postgres
  namespace: kong
spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgres
  serviceName: postgres
  template:
    metadata:
      labels:
        app: postgres
    spec:
      containers:
      - env:
          ...           
      volumeMounts:
        - mountPath: /var/lib/postgresql/data
          name: my-local-pv
          subPath: pgdata
      terminationGracePeriodSeconds: 60
  volumeClaimTemplates:
  - metadata:
      name: my-local-pv
    spec:
      storageClassName: local-storage
      accessModes:
      - ReadWriteOnce
      resources:
        requests:
          storage: 1Gi

kubectl获得pv：

NAME          CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                STORAGECLASS       REASON   AGE
