Openshift 构建 容器化mysql
1: 准备mysql镜像
- 查看Image streams
Openshift 提供了image streams管理镜像，"An image stream can be used to automatically perform an action, such as updating a deployment, when a new image, such as a new version of the base image that is used in that deployment, is created." - OpenShift Documentation
但是请注意，Image Streams并不是镜像仓库，只是镜像的一种映射，具体的镜像实体还需要自己准备。

2: 查看image: 发现并没有mysql 的镜像，下面来下载一下：
[[email protected] ~]# oc describe is mysql
Name: mysql
Namespace: shp
Created: 6 hours ago
Labels: <none>
Annotations: openshift.io/display-name=MySQL

Docker Pull Spec: <none>
Unique Images: 3
Tags: 4
5.7 (latest)
tagged from centos/mysql-57-centos7:latest
下载image 到本地： docker pull centos/mysql-57-centos7:latest
3: 从openshift web console界面部署mysql
- 新建一个deployment，并加入到project: shp中:
注意：上面创建mysql 的deployment 的时候，图中的"Enviroment Variable" 是要添加user_name,user_password,user_database 的参数的，否则，pod会创建失败的。
4创建好以后，尝试连接：
[[email protected] ~]# oc rsh mysql01-2-nayf1
sh-4.2$ mysql -usheng -psheng
mysql: [Warning] Using a password on the command line interface can be insecure.
