Fully Automated GitOps Deployment Pipeline
A production-grade GitOps pipeline where every infrastructure and application change flows through version-controlled workflows. Terraform provisions the Kubernetes cluster, Helm manages application releases, and ArgoCD continuously reconciles the cluster state with the Git repository. No manual kubectl commands — ever.
Tech Stack
The Challenge
Application deployments were manual and inconsistent across environments. There was no single source of truth for what was running in production, making debugging and rollbacks difficult and slow.
Architecture
Git is the single source of truth. Terraform provisions the Kubernetes cluster and supporting infrastructure. Helm charts define application configuration per environment. ArgoCD watches the Git repository and automatically applies changes to the cluster when a new commit is detected, ensuring the cluster always matches the declared state.
Deployment Strategy
GitHub Actions runs on every push: builds and tags the Docker image, updates the Helm chart values file with the new image tag, and commits back to the repository. ArgoCD detects the change and syncs the cluster automatically. No manual intervention required from build to production.
Outcome
Deployment frequency increased significantly. Rollback reduced to a single Git revert. Full visibility into what version is running in every environment at any time via ArgoCD dashboard.
