I have the following redis.yaml file in which I create a GKE persistent volume and try to mount it in a redis stateful set. But, the pod never comes up and it stays in Pending state forever. Any help ?

redis.yaml

apiVersion: v1
kind: Service
metadata:
  name: my-redis
spec:
  ports:
    - port: 6379
      name: my-redis
  type: LoadBalancer

apiVersion: v1
kind: PersistentVolumeClaim

    - ReadWriteOnce

    requests:
      storage: 10Gi

apiVersion: apps/v1beta2
kind: StatefulSet
metadata:
  name: my-redis
spec:
  selector:
    matchLabels:
      app: my-redis # has to match .spec.template.metadata.labels
  serviceName: my-redis
  replicas: 1

      labels:
        app: my-redis # has to match .spec.selector.matchLabels
    spec:
      nodeSelector:
        node-name: default
      containers:
        - name: redis
          image: redis:3.2-alpine
          args:
            [
              "--requirepass",
              "$(REDIS_PASS)",
              "--appendonly",
              "yes",
              "--save",
              "30",
              "1",
            ]
          ports:
            - containerPort: 6379
              name: redis
          env:
            - name: REDIS_PASS
              value: password
          volumeMounts:
            - name: my-redis-volume
              mountPath: /data
      volumes:
        - name: my-redis-volume
          persistentVolumeClaim:
            claimName: my-redis-volume-claim

The pod remains in Pending state even after 10s of minutes. I think I am missing something in the volume creation but not able to figure out what it is.
