Repeatability, Reliability, and Scalability through GitOps

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 provided a deeper dive into some of the basics of building a declarative file. Templating was also introduced to show how to add scalability to the benefits of a declarative approach to delivery and deployments. Templating is accomplished through templating engines, which are directed at specific declarative languages, namely Jsonnet for JSON and Helm for YAML. You should now know the difference between a flat file and a nested file, an object and an array, and XML, JSON, and YAML file design and syntax.

The next chapter will go through the basics of originalist GitOps with Visual Studio Code, Minikube, ArgoCD, GitHub Actions, and Flux.
