[BUG] Bookstack deployment fails with DB error

[mrcwatling]

Describe the bug
When I try and deploy Bookstack the installation completed but I am unable to access bookstack and when I go to the log of the container the following error is listed saying that the docker cannot connect to the database. The database is created but the container can't access it.

To Reproduce
Steps to reproduce the behavior:
Just ran the basic install, after the install completes I was unable to login and checked the logs. I have tried to install on V1 with portainer 1.2.4. and I have tried V2 with portainer 2.0.0 both fail
