Hi Slava,
The two pvc "ocai-mysql-claim" and "ocai-nb-claim" are consuming two pv which
are resides on one real storage. After deploying it on openshift origin
cluster, "empty" password worked when connecting to mysql.
And endpoint for glusterfs was destroyed soon after deployment, I didn't find
out the reason.
Then I modified the deployment as below. And mysql worked as expected.
Now I have two questions:
1, Could two pv reside on one real volume? For example, glusterfs volume
2, I found glusterfs related endpoints disappeared after running deployment
successfully. How could I debug such issue?

Hi，
When running mysql with other containers within one pod, it seemed that
environment variable "MYSQL_ROOT_PASSWORD" didn't work as expected.
Password set in "MYSQL_ROOT_PASSWORD" couldn't be used for connecting to mysql.
It doesn't work only when other containers are being created and when they try
to connect to mysql container? If yes, then it could be a race when mysql
container isn't ready while others try to connect to it.
