Question

我正在尝试在Kubernetes集群（Google Cloud Platform）中部署mongoDB。现在，我专注于部署的minikube本地版本。问题是我遇到了这样的错误： pod has unbound immediate PersistentVolumeClaims

这是我的配置文件，用于在minikube中设置mongodb：

服务文件：

apiVersion: v1
kind: Service
metadata:
  name: mongo
  labels:
    name: mongo
spec:
  ports:
    - port: 27017
      targetPort: 27017
  clusterIP: None
  selector:
    role: mongo

有状态设置文件：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: mongo
spec:
  selector:
    matchLabels:
      role: mongo
  serviceName: "mongo"
  replicas: 1
  template:
    metadata:
      labels:
        role: mongo
        environment: test
    spec:
      terminationGracePeriodSeconds: 10
      containers:
        - name: mongo
          image: mongo
          command:
            - mongod
            - "--replSet"
            - rs0
            - "--smallfiles"
            - "--noprealloc"
          ports:
            - containerPort: 27017
          volumeMounts:
            - name: mongo-persistent-storage
              mountPath: /data/db
        - name: mongo-sidecar
          image: cvallance/mongo-k8s-sidecar
          env:
            - name: MONGO_SIDECAR_POD_LABELS
              value: "role=mongo,environment=test"
  volumeClaimTemplates:
    - metadata:
        name: mongo-persistent-storage
        annotations:
          volume.beta.kubernetes.io/storage-class: "fast"
      spec:
        accessModes: [ "ReadWriteOnce" ]
        resources:
          requests:
            storage: 2Gi

存储类文件：

kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
  name: fast
provisioner: kubernetes.io/gce-pd
parameters:
  type: pd-ssd

我在这里想念什么？

Answer 1

我认为问题在于您正在尝试申请

provisioner: kubernetes.io/gce-pd

这不适用于GCE PD。

对于minikube，您可以创建hostPath pvc。 Read more

Answer 2

我在功能开发期间使用minikube，并且我也在运行MongoDB，建议您在使用minikube时使用hostPath，这是我的体积定义：

volume

apiVersion: "v1"
kind: "PersistentVolume"
metadata:
  name: "blog-repoflow-resources-data-volume"
  namespace: repoflow-blog-namespace
  labels:
    service: "resources-data-service"
    fsOwner: "1001"
    fsGroup: "0"
    fsMode: "775"
spec:
  capacity:
    storage: "500Mi"
  accessModes:
    - "ReadWriteOnce"
  storageClassName: local-storage
  hostPath:
    path: /home/docker/production/blog.repoflow.com/volumes/blog-repoflow-resources-data-volume

完整的集群已启动并正在运行，并且是开源的：repository。

还要检查stateful，volume claim和service的定义

K8s pod具有立即绑定的PersistentVolumeClaims-mongoDB
