### Issue Details

Fails to Launch in Azure
I think the real issue is that there are too many options. Can you simplify this down to just like 3 text boxes
### Repro steps (_if necessary, delete otherwise_)

1.press the button filled in the fields

Start with the wordpress-mysql-replication template at the linked repository path and reproduce the Azure launch using the supplied fields. Identify why deployment fails and determine which inputs can be reduced to about three text boxes; done means the template launches successfully with the simpler input experience.
