Why Choose This Project

Traditional CI/CD pipelines push code to production, but managing Kubernetes manifests and deployments manually can become complex. GitOps changes this by making Git the single source of truth for infrastructure and application state.

With tools like Argo CD and Flux, you achieve declarative, automated, and auditable deployments. This project is ideal for DevOps teams that want continuous delivery for Kubernetes with strong version control and rollback capabilities.

What You Get

• End-to-end GitOps workflow with Kubernetes.

• Argo CD or Flux setup for automated syncing from Git to cluster.

• CI pipeline integrated with GitHub/GitLab.

• Automated rollback and drift detection.

• Scalable, production-ready deployment patterns.

Key Features

Technology Stack

1. Container & Orchestration Layer

• Kubernetes (EKS, AKS, or GKE)

• Docker images

2. GitOps Layer

• Argo CD or Flux CD

• Helm or Kustomize for packaging manifests

3. CI/CD Integration

• GitHub Actions / GitLab CI for build & push

• Argo CD/Flux for continuous delivery

4. Observability

• Prometheus + Grafana for monitoring

• Loki/ELK stack for logging

5. Security

• Sealed Secrets / HashiCorp Vault for secret management

• RBAC and SSO integration in Argo CD

Working Flow

1. Developer Pushes Code

   • App code + Kubernetes manifests (YAML/Helm) are committed to Git.

2. CI Pipeline Runs

   • GitHub Actions / GitLab CI builds Docker image, pushes to registry.

   • Updates Kubernetes manifest with new image tag → commits back to Git.

3. GitOps Tool Syncs

   • Argo CD or Flux detects the Git change.

   • Applies updated manifests to the Kubernetes cluster.

4. Cluster State Drift Detection

   • If someone changes cluster resources manually, Argo CD/Flux detects drift.

   • Optionally auto-corrects to match Git.

5. Rollback if Needed

   • Revert to an older Git commit → cluster automatically rolls back.

Security Features

• Git commit history ensures auditability.

• RBAC in Argo CD/Flux controls who can sync and deploy.

• Sealed Secrets/Vault to manage sensitive data.

• SSO with OIDC for secure authentication.

Visualization Options

• Argo CD UI → shows app sync status & drift visually.

• Flux CLI & dashboards for sync status.

• Grafana dashboards for deployment health.

• Git commit logs as the deployment history.
