      labels:
        app: mysql
    spec:
      containers:
      - image: mysql:5.6.48
        name: mysql
        ports:
        - name: wp-port
          containerPort: 3306
        env:
         - name: MYSQL_ROOT_PASSWORD
           valueFrom:
             secretKeyRef:
               name: my-secret
               key: MYSQL_ROOT_PASSWORD
        volumeMounts:
         - name: db-data
           mountPath: "/var/lib/mysql"
        livenessProbe:
          tcpSocket:
            port: 3306
          initialDelaySeconds: 30
          timeoutSeconds: 1
      volumes:
        - name: db-data
          persistentVolumeClaim:
            claimName: pvc-mysql
          
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-svc 
spec:
  type: ClusterIP
  selector:

最终布署效果如下：

进入mysql容器创建wordpress数据库，使用node节点IP加端口号54548访问wordpress进行安装：

部署完成。
