GitOps
GitOps
Cloud-native Continuous Deployment
About the Book
GitOps is a way of implementing Continuous Deployment for cloud native applications. It focuses on a developer-centric experience when operating infrastructure, by using tools developers are already familiar with, including Git and Continuous Deployment tools.
Early Praise
"Software development nowadays requires to be fast and iterative, infrastructure needs to adapt and evolve with the same velocity. GitOps is fundamental for modern infrastructure implementation. With GitOps your source of truth is one or more Git repositories, your process is automated and, most likely, your infrastructure is implemented in a declarative manner. For over four years I've been helping companies implementing GitOps. In this book, you find a great introduction to GitOps and how to apply it to real-world use cases with great hands-on examples."
Vincenzo Ferme, Cloud Native Tech Lead at Kiratech
"GitOps - Cloud-native Continuous Deployment is at the heart of modern Cloud development, automation is king and efficiency is what you get. This GitOps book is very much the same as GitOps development: nice and handy."
Dr. Andreas Schönberger, Founder Lion5 GmbH
"Informative and concise introduction to a neat CI/CD method built around Git."
Dr. Michael Oberparleiter, Software consultant at TNG Technology Consulting
