Avoid "config/database.yml first" problem

How to avoid the:
"Please configure your config/database.yml first"

When "running" commands with the official redmine container?

[yosifkit]

What commands are you running and how are you running them?

As long as you are only setting the CMD, and using rails, rake, or passenger, then the entrypoint script will configure the database.yml for you based on the environment.

So, something like docker run -it --rm -v /path/to/my/files:/usr/src/redmine/files -e REDMINE_DB_MYSQL=mysql -e ... redmine:3.3 rake db:migrate should work.
