    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  selector:

2、创建 Deployment，SVC

apiVersion: v1

spec:
  type: NodePort
  ports:
  - name: mysql
    port: 3306
    targetPort: 3306
    nodePort: 30306
  selector:

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
spec:
  selector:
    matchLabels:
      app: mysql

          value: "123456"
        ports:
        - containerPort: 3306
          name: mysql
        volumeMounts:
        - name: mysql-persistent-storage
          mountPath: /var/lib/mysql
      volumes:

        persistentVolumeClaim:
          claimName: mysql-pv-claim
