GitOps

Overview In the previous post, we set up a homelab Kubernetes cluster using Dell OptiPlex Micro machines and completed the basic configuration. This post covers installing ArgoCD, a GitOps tool for declaratively managing all cluster components from a Git repository, and applying the App of Apps pattern to build a scalable infrastructure management system. Understanding GitOps What is GitOps? GitOps is an operational model first proposed by Alexis Richardson of Weaveworks in 2017. It uses a Git repository as the Single Source of Truth for infrastructure and application configurations. All infrastructure changes are tracked through Git commits, reviewed via Pull Requests, and reflected in the actual environment through automated processes, enabling infrastructure to be managed like code. ...

GitOps is an operating model that uses Git as the single source of truth for declarative infrastructure and application state, then synchronizes that state to running systems automatically. The term was introduced by Alexis Richardson, CEO of Weaveworks, in 2017 and later gained broad traction in the cloud-native community. By extending familiar Git workflows such as pull requests, code reviews, and branching into operations, GitOps has become a core practice in modern DevOps, especially when paired with declarative platforms like Kubernetes. ...
