Overview of this book

GitLab is an open source repository management and version control toolkit with functions for enterprises and personal software projects. It offers configurability options, extensions, and APIs that make it an ideal tool for enterprises to manage the software development life cycle. This book begins by explaining GitLab options and the components of the GitLab architecture. You will learn how to install and set up GitLab on-premises and in the cloud, along with understanding how to migrate code bases from different systems, such as GitHub, Concurrent Versions System, Team Foundation Version Control, and Subversion. Later chapters will help you implement DevOps culture by introducing the workflow management tools in GitLab and continuous integration/continuous deployment (CI/CD). In addition to this, the book will guide you through installing GitLab on a range of cloud platforms, monitoring with Prometheus, and deploying an environment with GitLab. You'll also focus on the GitLab CI component to assist you with creating development pipelines and jobs, along with helping you set up GitLab runners for your own project. Finally, you will be able to choose a high availability setup that fits your needs and helps you monitor and act on results obtained after testing. By the end of this book, you will have gained the expertise you need to use GitLab features effectively, and be able to integrate all phases in the development process.

Technical requirements

For managing omnibus installations, there is one central configuration file called gitlab.rb. You need to create it or copy an example. There is a template available that you can find at https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-config-template/gitlab.rb.template. It is not updated after upgrades as we are using these files just for demonstration purpose. In large parts of this chapter, I will quote and discuss parts of this file.

To follow along with the instructions in this chapter, please download the Git repository available on GitHub: https://github.com/PacktPublishing/Mastering-GitLab-12/tree/master/Chapter02.

Although GitLab can be installed on a variety of platforms, in this chapter we choose Debian 10 (Buster) to show you how it's done. You can download Debian from http://debian.org.
