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.

Configuring GitLab settings at the group level

The admin area is only accessible to users with the admin role, but other roles can configure settings too. If you, as a user, have been granted permission to add groups, you can change the settings of the groups you have created. If you navigate to Your Groups from the top-level menu, you can access the settings from the left-hand side menu.

Here, you will see a submenu with the items that you can configure. It looks a lot like the UI in the admin area but is, of course, scoped to the group:

In GitLab 12.0, a new interesting feature has been added to the General pane for group settings: Restrict address by IP address. It is an Enterprise feature and, by using it, you can make sure that certain IP addresses aren't allowed to access group content. In the following screenshot, you can see that 192.168.1.0/24 is the only IP range...
