This project demonstrates an enterprise-grade GitOps Continuous Deployment (CD) pipeline using ArgoCD to manage and automate application deployments on a Kubernetes cluster. By leveraging the GitOps paradigm, Git acts as the single source of truth for all system configurations, ensuring declarative, automated, and audit-friendly infrastructure management.
Architecture & Workflow Breakdown
Declarative Source Control (Git):
Separation of concerns with dedicated repositories for Application Source Code and Infrastructure Manifests (Helm Charts / Kubernetes YAMLs).
GitOps Controller (ArgoCD):
ArgoCD actively monitors the Kubernetes manifest repository for changes (commits/pull requests).
Reconciliation Loop: ArgoCD continuously compares the live state inside the Kubernetes cluster with the desired state defined in Git.
Automated Synchronization & Deployment:
Automatically synchronizes (Sync) configuration changes, applying updates directly into the cluster with zero downtime.
Traffic & Routing:
NGINX Ingress Controller handles incoming HTTP/HTTPS traffic and routes requests to the backend microservices.
Observability & Metrics:
Integrated health checks and deployment metrics, allowing monitoring tools (Prometheus & Grafana) to scrape operational data.
