1. 制作mariadb镜像，在Dockerfile中初始化数据库，源码：

https://github.com/zhanggq/mariadb

 

2. 制作自己的web镜像，后端用go编写，前端用的amaze，开放端口8082，源码暂不提供

 

3. Dashboard上点创建，粘贴yaml，启动mariadb rc

apiVersion: v1

kind: ReplicationController metadata:   name: mysql spec:   replicas: 1   selector:     app: mysql   template:     metadata:       labels:         app: mysql     spec:         containers:         - image: registry.cn-hangzhou.aliyuncs.com/zhanggq/mariadb:v10.1           name: mysql           resources:             limits:               cpu: "2"               memory: 2Gi           ports:           - containerPort: 3306           env:           - name: MYSQL_ROOT_PASSWORD             value: "123456"

4. 启动mariadb svc

apiVersion: v1

kind: Service metadata:   name: mysql spec:   ports:   - name: mysql-svc     port: 3306     targetPort: 3306     nodePort: 31101   selector:     app: mysql   type: NodePort

 

5. 启动amaze rc

apiVersion: v1

kind: ReplicationController metadata:   name: amaze spec:   replicas: 1   selector:     app: amaze   template:     metadata:       labels:         app: amaze     spec:         containers:         - image: registry.cn-hangzhou.aliyuncs.com/zhanggq/amaze:v1.0           name: amaze           resources:             limits:               cpu: "1"               memory: 1Gi           ports:           - containerPort: 8082

 

6. 启动amaze svc

apiVersion: v1

kind: Service metadata:   name: amaze spec:   ports:   - name: amaze-svc     port: 8082     targetPort: 8082     nodePort: 30082   selector:     app: amaze   type: NodePort

 

遇到的问题

1. docker启动容器报错：

docker: Error response from daemon: mkdir /var/lib/docker/overlay/64d4cbac6ef69d5b84fc753e83dc2849f14e43177d0e9d

a532eb61499ce7e2fc-init/merged/dev/shm: invalid argument.

解决办法：升级内核

原内核Kernel Version: 3.10.0-229.el7.x86_64

升级后内核4.6.0-1.el7.elrepo.x86_64

 

2. 手工改了一下web应用里面的配置，远程连接mysql数据库10.233.104.69:3306

后来发现其实是没搞清楚Kubernetes中Service的概念。具体的分析在下文介绍。
