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.

Mirroring SVN and GIT

In order to mirror SVN with Git, we will use the SubGit tool (https://subgit.com/), which is maintained and sold by TMate software. You can download a version for your operating system or choose the basic one, which is a multiplatform Java binary. If you unzip the package you downloaded, the SubGit tool can be found in the bin directory.

SubGit should be set up on your Git server. It will scan the settings for the remote SVN repository you specify, then download SVN revisions and convert them into Git commits. SubGit keeps both repositories synchronized. When a user pushes a new commit to Git, SubGit converts and tries to update SVN. It also gets new revisions from SVN as soon as they appear. SVN and Git users see each other's commits as if they were all working on the same versioning system. SubGit makes sure that possible conflicts don't occur...
