Installation

Prerequisites

• ArgoCD installed in your cluster (in argocd namespace)
• Git repository access to https://github.com/sqe/esddns

Quick Start: Development

# Deploy development applications
kubectl apply -k argocd/dev/

Quick Start: Production

# Deploy production applications
kubectl apply -k argocd/prod/

Bootstrap All (includes setup script)

cd argocd/bootstrap
./argocd-setup.sh

Environment Configurations

Development (argocd/dev/)

• Auto Sync: Enabled (automatic prune + selfHeal)
• Replicas: 1
• AppProject: esddns-dev
• Namespace: esddns-operator-dev
• Applications:
  • esddns-operator-helm-dev (Helm-based)
  • esddns-operator-kustomize-dev (Kustomize-based)

Deploy with:

kubectl apply -k argocd/dev/

Production (argocd/prod/)

• Auto Sync: Disabled (manual sync only)
• Replicas: 3
• AppProject: esddns-prod
• Namespace: esddns-operator
• Applications:
  • esddns-operator-helm-prod (Helm-based)
  • esddns-operator-kustomize-prod (Kustomize-based)

Deploy with:

kubectl apply -k argocd/prod/

Syncing Applications

Development (Auto Sync)

Changes are automatically deployed when committed to Git.

Production (Manual Sync)

Require human approval:

# Review changes in ArgoCD UI or CLI
argocd app get esddns-operator-helm-prod

# Approve and sync manually
argocd app sync esddns-operator-helm-prod

Configuration

Helm Values

• Dev: Uses values.yaml + values-development.yaml
• Prod: Uses values.yaml + values-production.yaml

Edit in: helm/esddns-operator/values*.yaml

Kustomize Overlays

• Dev: Uses k8s/overlays/development
• Prod: Uses k8s/overlays/production

Edit in: k8s/overlays/{dev|prod}/kustomization.yaml

Monitoring

Check application status in ArgoCD UI:

1. Navigate to https://your-argocd-instance
2. Select desired application
3. View sync status and resource health

Or use CLI:

# Development
argocd app get esddns-operator-helm-dev
argocd app get esddns-operator-kustomize-dev

# Production
argocd app get esddns-operator-helm-prod
argocd app get esddns-operator-kustomize-prod

Cleanup

# Remove development applications
kubectl delete -k argocd/dev/

# Remove production applications
kubectl delete -k argocd/prod/

# Remove both
kubectl delete -k argocd/dev/
kubectl delete -k argocd/prod/

Next Steps

1. Commit ArgoCD files to Git repository
2. Deploy to ArgoCD: kubectl apply -k argocd/dev/ (or prod)
3. Monitor in ArgoCD UI or CLI
4. See DEPLOYMENT.md for advanced usage
