Working with the Rancher UI

I want to ask you guys. Help me with Rancher UI. As I step by step to do the same in this topic:

http://forums.rancher.com/t/working-with-rancher-compose/283/13

only through Rancher UI.
Thanks to those who respond to my request.

There is an entire section in the docs about how to use Rancher UI. Please take a look through the documentation. I’ve only included the link to add services, but there is a whole navigation section for how to use the Rancher UI.

Help me please with such a problem. I try to deploy wordpress with Rancher UI. But does not bind the application with the database:

That containers:

MariaDB


Wordpress

Where I made a mistake?

db and wordpress
CONSOLE - None

wordpres
ENVIRONMENT VARS - blank

now works
