By: Bryan Feuling

Overview of this book

The world of software delivery and deployment has come a long way in the last few decades. From waterfall methods to Agile practices, every company that develops its own software has to overcome various challenges in delivery and deployment to meet customer and market demands. This book will guide you through common industry practices for software delivery and deployment. Throughout the book, you'll follow the journey of a DevOps team that matures their software release process from quarterly deployments to continuous delivery using GitOps. With the help of hands-on tutorials, projects, and self-assessment questions, you'll build your knowledge of GitOps basics, different types of GitOps practices, and how to decide which GitOps practice is the best for your company. As you progress, you'll cover everything from building declarative language files to the pitfalls in performing continuous deployment with GitOps. By the end of this book, you'll be well-versed with the fundamentals of delivery and deployment, the different schools of GitOps, and how to best leverage GitOps in your teams.

This chapter discussed the different concepts related to building out verified GitOps using Ansible and Harness. Emphasis was placed on the different areas of balance that exist across manifest size and number, configurable and opinionated pipelines, and so on. Finally, the chapter went a bit deeper into how verified GitOps is shown in Harness.

After discussing originalist GitOps in depth in the last chapter, and verified GitOps in this chapter, it is important to show the pitfalls of GitOps. By understanding common issues that are encountered on the way to implementing GitOps, a team can properly navigate their GitOps implementation, which will be shown in the next chapter.
