Adding more variables
We welcome merge requests to make more settings configurable by using variables.
Make changes to the config/initializers/1_settings.rb file, and use the
naming scheme GITLAB_#{name in 1_settings.rb in upper case}.
Omnibus configuration
To set environment variables, follow these instructions.
It's possible to preconfigure the GitLab Docker image by adding the environment
variable GITLAB_OMNIBUS_CONFIG to the docker run command.
For more information, see the Pre-configure Docker container
section of the Omnibus GitLab documentation.
