ArgoCD

ELI5 — The Vibe Check

ArgoCD watches your Git repo and automatically syncs your Kubernetes cluster to match. Change a YAML file, and ArgoCD deploys it. Drift from the desired state? ArgoCD fixes it. It's like having an obsessively organized roommate who undoes every mess you make.

Real Talk

ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It continuously monitors Git repositories containing Kubernetes manifests and ensures cluster state matches the desired state in Git. Supports Helm, Kustomize, and plain YAML with automated or manual sync and rollback capabilities.
