Environment variables (FREE SELF)

GitLab exposes certain environment variables which can be used to override their defaults values.

People usually configure GitLab with /etc/gitlab/gitlab.rb for Omnibus installations, or gitlab.yml for installations from source.

You can use the following environment variables to override certain values:

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.
