A comprehensive GitOps learning laboratory featuring multiple tools and workflows for modern DevOps practices.

This repository contains hands-on demonstrations of popular GitOps tools and patterns:

• Kind + ArgoCD: Kubernetes-native GitOps with declarative deployments
• Terraform + Atlantis: Infrastructure as Code with automated PR workflows
• Flux: GitOps toolkit with automatic image updates

# Clone the repository
git clone https://github.com/your-org/gitops-lab.git
cd gitops-lab

# Start Kind cluster with ArgoCD
make kind-argocd

# Verify ArgoCD is running
kubectl get pods -n argocd

• Local Kubernetes cluster with ArgoCD
• Sample guestbook application
• Declarative GitOps workflows

• Infrastructure as Code automation
• PR-based Terraform workflows
• AWS S3 bucket provisioning example

# Kind + ArgoCD
make kind-argocd          # Start Kind cluster with ArgoCD
make argocd-port-forward  # Port-forward ArgoCD UI (localhost:8080)

# Atlantis
make atlantis-up          # Start Atlantis with Docker Compose
make atlantis-down        # Stop Atlantis

# Flux
make flux-bootstrap       # Bootstrap Flux in Kind cluster
make flux-reconcile       # Force reconciliation

# Utilities
make destroy              # Clean up all resources
make lint                 # Run linting checks
