              exec:
                command: ["sh", "-c", "mysqladmin -uroot -p$MYSQL_ROOT_PASSWORD shutdown"]
          resources:
            limits:

              valueFrom:
                secretKeyRef:
                  name: sec-mysql-pass
                  key: MYSQL_ROOT_PASSWORD
            - name: MYSQL_DATABASE
              value: halo_db
            - name: MYSQL_USER
              value: halo
            - name: MYSQL_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: sec-mysql-pass
                  key: MYSQL_HALO_PASSWORD
          volumeMounts:
            - name: mysql-data
              mountPath: /var/lib/mysql
      volumes:
        - name: mysql-data
          persistentVolumeClaim:

    front: halo

5. 应用资源模板

kubectl apply -f .

6. 查看容器状态

kubectl get pods -n middleware deploy-mysql-5fddfdfd46-vphnv

STATUS为Running则代表mysql启动成功

        args:
          - --spring.r2dbc.url=r2dbc:pool:mysql://svc-mysql.middleware.svc.cluster.local:3306/halo_db
          - --spring.r2dbc.username=halo
          - --spring.r2dbc.password=<数据库账号halo的密码>
          - --spring.sql.init.platform=mysql
          - --halo.external-url=<http://SolopaceGem组网IP:NodePort端口>
        readinessProbe:
          httpGet:
            path: /actuator/health/readiness
            port: 8090
          initialDelaySeconds: 30
          periodSeconds: 60
          timeoutSeconds: 5
        livenessProbe:
          httpGet:
            port: 8090
            path: /actuator/health/readiness

            memory: 256Mi
        volumeMounts:
          - mountPath: /root/.halo2
            name: halo-data
      volumes:
        - name: halo-data
          persistentVolumeClaim:
            claimName: pvc-halo-data


      

2. 创建存储卷PVC存放halo的持久化数据

vim pvc-halo.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-halo-data
  labels:
    app: halo
spec:
  accessModes:
    - ReadWriteOnce

    requests:
      storage: 5Gi
  storageClassName: alibabacloud-cnfs-nas

3. 创建NodePort类型的Service暴露管理页面

      targetPort: 8090
      name: http
	  nodePort: 31111
  selector:
    app: halo

4. 应用资源模板

kubectl apply -f .

5. 查看容器状态

kubectl get pods -n middleware deploy-halo-5c5864b648-kx6x7

STATUS为Running则代表mysql启动成功

通过SolopaceGem完成Kubernetes Work节点与用户端的组网

1. 任选一台Kubernetes Work节点安装SolopaceGem

Kubernetes本身具有容器运行环境，因此我们选择最简单方便的Docker来安装SolopaceGem

• 执行以下命令启动SolopaceGem Docker客户端

sudo docker run -d --name=SolopaceGem -v /var/lib:/var/lib -v /dev/net/tun:/dev/net/tun --network=host --restart=always --cap-add=NET_ADMIN --cap-add=NET_RAW doaction/solopacegem:latest

• 获取SolopaceGem组网链接

sudo docker exec SolopaceGem solopacegem status

• 复制组网链接地址至浏览器打开

• 创建组网并加入

成功加入组网

2. 在客户端上安装SolopaceGem

• 下载SolopaceGem客户端

在官网下载适用于您设备系统的客户端。

官网：https://solopace.doaction.pro/

下载完成后，按照提示进行安装即可。

• 安装后登录/注册（未注册用户将会自动注册）

此处使用之前安装Docker客户端是注册的账号登录

• 客户端加入组网

登录后选择已有网络ID，将会自动列出之前创建的网络

选择网络ID并加入即可

• 连接网络

当在在线设备列表中看到当前客户端与Kubernetes Docker客户端都处于在线状态时，说明组网成功。

访问CMS

组网成功后，在管理端PC上通过访问k8s work节点的SolopaceGem组网IP+Halo服务的NodePort端口，即可访问Halo的管理页面，第一次访问时需要做一些初始化配置，按照提示完成即可。
