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 operational methodology that uses Git as the Single Source of Truth to manage declarative states of infrastructure and applications and deploy them automatically. The term was first proposed by Alexis Richardson, CEO of Weaveworks, in 2017 and introduced to the cloud-native community. GitOps extends the Git workflow familiar to developers (Pull Requests, code reviews, branching strategies, etc.) into the infrastructure operations domain, and has become a core paradigm of modern DevOps practices when combined with declarative infrastructure platforms like Kubernetes. ...
