Chapter 1. Introduction
With the advent of practices such as infrastructure as code (IaC), software development has pushed the boundaries of platforms where you can run applications. This becomes more frequent with programmable, API-driven platforms such as public clouds and open source infrastructure solutions. While some years ago developers were only focusing on application source code, today they also have the opportunity to code the infrastructure where their application will run. This gives control and enables automation, which significantly reduces lead time.
A good example is with Kubernetes, a popular open source container workload orchestration platform and the de facto standard for running production applications, either on public or private clouds. The openness and extensibility of the platform enables automation, which reduces risks of delivery and increases service quality. Furthermore, this powerful paradigm is extended by another increasingly popular approach called GitOps.
1.1 What Is GitOps?
GitOps is a methodology and practice that uses Git repositories as a single source of truth to deliver infrastructure as code. It takes the pillars and approaches from DevOps culture and provides a framework to start realizing the results. The relationship between DevOps and GitOps is close, as GitOps has become the popular choice to implement and enhance DevOps, platform engineering, and SRE.
GitOps is an agnostic approach, and a GitOps framework can be built with tools ...
