Use Persistent Volume Claims (PVC)-Scalable Open Financial Architecture(SOFAStack)-阿里云帮助中心

After a PersistentVolumeClaim (PVC) is created, you can use the PVC when you create a pod.

Important

A cloud disk cannot be mounted across availability zones (AZs). Therefore, after a PVC of the volumeBindingMode: Immediate type is created, the pod/workload that uses the PVC must be prevented from running in the same AZ of the PV/PVC by using nodeSelector/nodeAffinity.
At present, LDC Hybrid Cloud (LHC) is not connected to Alibaba Cloud NAS or cloud disk storage. To use the storage feature, you must install third-party storage plug-ins.

Prerequisites

You have created a PVC. For more information, see Create a PVC.

Procedure

Go to the Clusters page.
Click the name of the target cluster to go to the Cluster Details page and click the Workload tab.
In the left-side menu, click Pods, and then click Create Pods.

In the input box that appears, enter the YAML content, and then click Submit.

Example:

 apiVersion: v1
 kind:Pod
 metadata:
   name: pod-with-disk
namespace:default
   labels:
     app: nginx
 spec:
   tolerations:
- key: node.kubernetes.io/unreachable
     effect:NoSchedule
operator:Exists
   automountServiceAccountToken:false
   containers:
- name: busybox
     image: reg-cnsh-nf.cloud.alipay.com/library/busybox
     command:["sleep","3000"]
     ports:
- containerPort:80
     volumeMounts:
- name: data
         mountPath:"/data"
   volumes:
- name: data
       persistentVolumeClaim:
         claimName: test-pvc

After the container runs, the status of the pod changes to Running.

# kubectl get pod
NAME            READY   STATUS    RESTARTS   AGE
pod-with-disk   1/1Running0103s
