How To Install and Configure GitLab on Ubuntu

GitLab is an open-source application primarily used to host Git repositories, with additional development-related features like issue tracking. It is designed to be hosted using your own infrastructure, and provides flexibility in deploying as an internal repository store for your development team, a public way to interface with users, or a means for contributors to host their own projects.
