Kubernetes nfs在聲明中定義路徑

Question

我想用nfs創建通用持久性卷。

PV（NFS）：

common-data-pv  1500Gi  RWO   Retain 
192.168.0.24 /home/common-data-pv 

我希望有一個如權利要求或吊艙（安裝權利要求）訂閱共數據-PV可以定義路徑例如：

/home/common-data-pv/www-site-1(50GI) 
/home/common-data-pv/www-site-2(50GI) 

但我在未找到記錄我如何定義這個。

我的光伏實際的conf：

kind: PersistentVolume 
apiVersion: v1 
metadata: 
    name: common-data-pv 
    labels: 
    type: common 
spec: 
    capacity: 
    storage: 1500Gi 
    accessModes: 
    - ReadWriteMany 
    nfs: 
    server: 192.168.122.1 
    path: "/home/pv/common-data-pv" 



kind: PersistentVolumeClaim 
apiVersion: v1 
metadata: 
    name: common-data-pvc 
    namespace: kube-system 
spec: 
    accessModes: 
    - ReadWriteMany 
    resources: 
    requests: 
     storage: 10Gi 
    selector: 
    matchLabels: 
     type: common 

使用例：

apiVersion: v1 
kind: ReplicationController 
metadata: 
    name: nfs-web-1 
    namespace: kube-system 
spec: 
    replicas: 2 
    selector: 
    role: web-frontend 
    template: 
    metadata: 
     labels: 
     role: web-frontend 
    spec: 
     containers: 
     - name: web 
     image: nginx:alpine 
     ports: 
      - name: web 
      containerPort: 80 
     volumeMounts: 
      # name must match the volume name below 
      - name: nfs 
       mountPath: "/usr/share/nginx/html" 
     volumes: 
     - name: nfs 
     persistentVolumeClaim: 
      claimName: common-data-pvc 

apiVersion: v1 
kind: ReplicationController 
metadata: 
    name: nfs-web-2 
    namespace: kube-system 
spec: 
    replicas: 2 
    selector: 
    role: web-frontend 
    template: 
    metadata: 
     labels: 
     role: web-frontend 
    spec: 
     containers: 
     - name: web 
     image: nginx:alpine 
     ports: 
      - name: web 
      containerPort: 80 
     volumeMounts: 
      # name must match the volume name below 
      - name: nfs 
       mountPath: "/usr/share/nginx/html" 
     volumes: 
     - name: nfs 
     persistentVolumeClaim: 
      claimName: common-data-pvc

要使用你只需要一個volumeMounts部分和卷添加到您的清單中的要求。下面是一個用於nginx的複製控制器，它將使用您的聲明。請注意使用相同PVC名稱的最後一行。

apiVersion: v1 
kind: ReplicationController 
metadata: 
    name: nfs-web 
    namespace: kube-system 
spec: 
    replicas: 2 
    selector: 
    role: web-frontend 
    template: 
    metadata: 
     labels: 
     role: web-frontend 
    spec: 
     containers: 
     - name: web 
     image: nginx:alpine 
     ports: 
      - name: web 
      containerPort: 80 
     volumeMounts: 
      # name must match the volume name below 
      - name: nfs 
       mountPath: "/usr/share/nginx/html" 
     volumes: 
     - name: nfs 
     persistentVolumeClaim: 
      claimName: common-data-pvc
