Overview of this book

DevOps is the most widely used software engineering culture and practice that aim sat software development and operation. Continuous integration is a cornerstone technique of DevOps that merges software code updates from developers into a shared central mainline. This book takes a practical approach and covers the tools and strategies of DevOps. It starts with familiarizing you with DevOps framework and then shows how toper form continuous delivery, integration, and deployment with DevOps. You will explore DevOps process maturity frameworks and progression models with checklist templates for each phase of DevOps.

Source Code Review – Gerrit


Code review is an important function in the software development framework. Having a good collaborative tool like Gerrit for a code review process is very appropriate and needed. Gerrit initiates a pull-based workflow to initiate change requests, wherein comments are included even for source code to allow the change to be merged into the code repository through the workflow process. Gerrit maintains a local repository of the mirrored Git project repositories with reference repositories. Gerrit creates another maintenance branch from master branch to track reviews to the code; it creates a change-id identifier for the commit message to keep track of each change in a code review.

Gerrit allows for code change comparisons and a reviewer can give one of five ratings:

  • +2: Looks good, approved

  • +1: Looks good, but needs additional approval

  • 0: No comments

  • -1: Suggest not submit this

  • -2: Block the submit
