我是Openshift开发的新手，正在尝试创建mysql db pod。有人可以给我推荐一些参考资料吗？据我所知：（使用oc cli的PS）
登录到openshift在线后在命令行上创建数据库：
oc new-app -e MYSQL_USER=churchill -e MYSQL_PASSWORD=passme -e MYSQL_DATABASE=mydatabase openshift/mysql-56-centos7
现在已经创建了数据库，我可以在Openshift mysql实例日志中找到它：

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/rh/rh-mysql56/root/usr/bin/mysqladmin -u root password 'new-password'
/opt/rh/rh-mysql56/root/usr/bin/mysqladmin -u root -h mysql-56-centos7-2-vhjzz password 'new-password'
Alternatively you can run:
/opt/rh/rh-mysql56/root/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.

这是我的问题，我觉得这里有问题，任何人都可以直接帮助或提出一些建议吗？ （关闭命令很可怕）
似乎是该图像的正常日志。只要您可以通过mysql进行连接，就可以了。试试：
oc get pods
oc rsh <POD>
mysql -u <MYSQL_USER> -p<MYSQL_PASSWORD> -h <HOSTNAME> <MYSQL_DATABASE>
