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.

Chapter 5: The Purist GitOps – Continuous Deployment Everywhere

The second school of thought can be categorized as purist. By adhering to the basic tenants of what makes GitOps beneficial, the purist mindset is broader in scope than the originalist school is.

As we mentioned in an earlier chapter, storing configuration code in a central source code manager is nothing new. But what makes GitOps, and especially purist GitOps, different from traditional practices is using source code management systems as a source of truth.

In this chapter, we're going to cover the following main topics:  

  • Purist GitOps basics
  • Servers, containers, and serverless deployment as code
  • Declarative files overload
  • Benefits and drawbacks of purist GitOps
  • Common purist GitOps tools
