It facilitates the adoption of GitOps, where teams leverage declarative configuration and infrastructure definitions from Git as the single source of truth. What is ArgoCD? ArgoCD is a Kubernetes-native continuous deployment (CD) tool. Unlike external CD tools that only enable push-based deployments, Argo CD can pull updated code from Git repositories and deploy it directly to Kubernetes resources. It enables developers to manage both infrastructure configuration and application updates in one system. There are many features of ArgoCD : 1. Whole Kubernetes configuration defined as code in GIT Repository. 2. Web user interface and command-line interface (CLI). 3.
