To manage omnibus installs, you need to use a central configuration file called gitlab.rb. You need to create it yourself or copy an example of one. A template of this configuration file is available at https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-config-template/gitlab.rb.template. Please note that it isn't updated after upgrades. We will quote and discuss parts of this file in this chapter.
To follow along with the instructions in this chapter, please download this book's GitHub repository, along with the examples that are available, at https://github.com/PacktPublishing/Mastering-GitLab-12/tree/master/Chapter03.
