1、创建mysql pv文件

[root@k8s-node1 mysql]# cat mysql_pv.yaml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-data
spec:
  capacity:
    storage: 1Gi 
  accessModes:
  - ReadWriteMany 
  nfs: 
    path: /app/mysql_data      #nfs共享目录
    server: 192.168.29.175     #nfs服务器地址，nfs服务需要自行搭建
  persistentVolumeReclaimPolicy: Recycle 

2、创建mysql pvc文件

[root@k8s-node1 mysql]# cat mysql_pvc.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: mysql-data
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi

3、创建mysql deployment文件

[root@k8s-node1 mysql]# cat mysql_deployment.yaml 
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: mysql
spec:
  replicas: 1
  template:
    metadata:
      labels:
        name: mysql
    spec:
      containers:
      - name: mysql
        image: mysql:5.7
        imagePullPolicy: IfNotPresent
        ports:
        - name: db
          containerPort: 3306
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "123456com"
        volumeMounts:
        - mountPath: /var/lib/mysql
          name: mysql-data
      volumes:
      - name: mysql-data
        persistentVolumeClaim:
          claimName: mysql-data

4、创建mysql svc文件

[root@k8s-node1 mysql]# cat mysql_svc.yaml 
apiVersion: v1
kind: Service
metadata:
  name: mysql
spec:
  type: NodePort
  ports:
    - port: 3306
      targetPort: 3306
      nodePort: 9006
  selector:
    name: mysql

5、查看部署结果

[root@k8s-node1 mysql]# kubectl get pod
NAME                       READY     STATUS    RESTARTS   AGE
mysql-67d458b8b4-w55pp     1/1       Running   0          16m

[root@k8s-node1 ~]# kubectl get svc
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
mysql        NodePort    10.1.177.197   <none>        3306:9006/TCP    16m
