The authors of this book have done a great job not only covering the topic and process of GitOps but also all of the additional concerns that come with this type of workflow.
GitOps and Kubernetes introduces a radical idea—managing your infrastructure with the same Git pull requests you use to manage your codebase. In this in-depth tutorial, you’ll learn to operate infrastructures based on powerful-but-complex technologies such as Kubernetes with the same Git version control tools most developers use daily. With these GitOps techniques and best practices, you’ll accelerate application development without compromising on security, easily roll back infrastructure changes, and seamlessly introduce new team members to your automation process.
The tools to monitor and manage software delivery and deployment can be complex to set up and intimidating to learn, especially when you apply them to applications deployed using Docker and Kubernetes. Imagine, instead, managing your entire Kubernetes infrastructure with Git pull requests! What might at first sound ridiculous is quickly becoming one of the most reliable ways to do Continuous Delivery. Dubbed “GitOps”, this new method uses Git as the “single source of truth” and allows you to manage your infrastructure as a codebase, just like you manage application code. Using declarative tools such as Kubernetes for automating deployment and scaling, GitOps gives you a single control interface, making it easy to assess and roll back changes.
GitOps and Kubernetes is half reference, half practical tutorial for operating Kubernetes the GitOps way. You’ll learn the GitOps best practices, techniques, and tools that simplify using Kubernetes to deliver enterprise-scale software faster, all without compromising on security. Through fast-paced chapters, you’ll unlock the benefits of GitOps for flexible configuration management, monitoring, robustness, multi-environment support, and discover tricks and tips for managing secrets in the unique GitOps fashion. When you’re done, you’ll be able to implement and manage a scalable Continuous Delivery pipeline that makes it easy to trace changes, rollback mistakes, and clearly validate and audit container deployments.
