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.

The best way to enforce standards and prevent requirements overload would be to build a highly configurable solution. The goal would be to have the developers only provide artifact and environment configurations. The rest of the requirements would be enforced by the solution itself.

One of the recent industry trends has been to leverage declarative language files to provide configuration requirements. A declarative language, such as YAML, JSON, or XML, leverage a key:value style, often in a nesting layout for easy data storage, access, and readability. During their research, the teams discovered that most tools that were cloud native would use...
