About This Architecture

Production-grade GitOps CI/CD on GCP combines GitHub Actions for automated container builds with ArgoCD for declarative Kubernetes deployments on GKE. Developers push code to the app-source repository, triggering GitHub Actions to build Docker images tagged by commit SHA, push to Docker Hub, and update deployment manifests in the gitops-manifests repository. ArgoCD continuously reconciles the GitOps repository with the GKE cluster, auto-syncing and self-healing the production namespace to maintain desired state. This architecture enforces Git as the single source of truth, enabling immutable deployments, audit trails, and rapid rollbacks across GCP infrastructure. Fork and customize this diagram to adapt the CI/CD pipeline stages, registry endpoints, or GKE cluster configuration to your organization's deployment workflow.

How do I set up a production GitOps CI/CD pipeline on GCP using GitHub Actions and ArgoCD?

This diagram shows a complete GitOps workflow: GitHub Actions builds Docker images tagged by commit SHA and pushes to Docker Hub, then updates Kubernetes manifests in a GitOps repository. ArgoCD continuously monitors the repository and auto-syncs deployments to your GKE cluster, ensuring production state always matches Git. This approach provides immutable deployments, audit trails, and instant ro
