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, together with tools ensuring the actual state of infrastructure and applications converges towards the desired state declared in Git. With Git at the center of your delivery pipelines, developers can make pull requests to accelerate and simplify application deployments and operations tasks to your infrastructure or container-orchestration system (e.g. Kubernetes).

Why is GitOps awesome?

It increases developer productivity, enhances developer experience, improves stability, all while having higher reliability, higher consistency and stronger security guarantees.

Modern software development practices assume support for reviewing changes, tracking history, comparing versions, and rolling back bad updates; GitOps applies the same tooling and engineering perspective to managing the systems that deliver direct business value to users and customers.
