Can that be mended?

(I know that it'll fall over later due to mandatory precompile)

@friism talked about this on hipchat, but just wanted to circle back around. This is b/c we don't create a config/databse.yml which is required for Rails < 4.1. Without conditional programming support in Dockerfile, we'll need to resort to bash or something else to do it.

@friism it doesn't even mention compiling assets at all?

Hey guys,

did you find a solution for this? I still have the problem... My only workaround was to clone this Dockerfile and add a RACK_ENV variable manually.

Edit: I'm using Rails 4.2.5.
