Скачать или смотреть What is GitOps

GitOps is a way to do Kubernetes cluster management and application delivery. It works by using Git as a single source of truth for declarative infrastructure and applications. With Git at the center of your delivery pipelines, developers can make pull requests to accelerate and simplify application deployments and operations tasks to Kubernetes.

An operating model for building cloud native applications
GitOps can be summarized as these two things:

1) An operating model for Kubernetes and other cloud native technologies, providing a set of best practices that unify deployment, management and monitoring for containerized clusters and applications.

2) A path towards a developer experience for managing applications; where end-to-end CICD pipelines and git workflows are applied to both operations, and development.
