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.

Before getting into the actual work of implementing a GitOps practice or tool, it is important to know about how a declarative file is built, structural syntax, different language types, and templatizing capabilities. Once the basics are understood, a team can build upon a standard that will be shared across a company.

An important thing to understand about choosing a declarative language to standardize on is that a company or team doesn't have to standardize on one language. Some tools have the ability to leverage multiple declarative language types, and if a solution is chosen that only supports one declarative language type, then there are tools that exist that can help convert declarative languages from one type to another.

In addition to tools that leverage declarative languages, there are also platforms that leverage declarative languages. For example, Kubernetes is well known for using YAML...
