  • Integration credentials for Jenkins, ArgoCD
  • Note: Use External Secrets Operator with Vault in production

🔗 Integration Points

Configured:

  • ✅ GitHub OAuth (authentication)
  • ✅ GitHub API (repository discovery)
  • ✅ Jenkins API (CI/CD status)
  • ✅ ArgoCD API (deployment status)
  • ✅ Kubernetes API (resource monitoring)
  • ✅ Prometheus (metrics collection)

📊 Observability

Metrics:

  • ServiceMonitor enabled for Prometheus
  • Metrics endpoint: /metrics
  • CloudNativePG PodMonitor for PostgreSQL

Health Checks:

  • Liveness probe: /healthcheck (60s initial delay)
  • Readiness probe: /healthcheck (30s initial delay)

Logging:

  • Backstage logs to stdout/stderr
  • PostgreSQL logs via CloudNativePG
  • Ready for Fluent Bit collection

🧪 Testing

BDD Tests: tests/bdd/features/backstage-deployment.feature

9 test scenarios covering:

  1. Service Accessibility
  2. Authentication Success
  3. Authentication Failure Redirect
  4. Core Service Functionality
  5. High Availability Deployment
  6. External PostgreSQL Integration
  7. Secure Ingress Configuration
  8. Prometheus Metrics Exposure
  9. Resource Allocation and Stability

🚀 Deployment Instructions

Prerequisites:

  1. Kubernetes cluster (1.28+) running
  2. ArgoCD installed and configured
  3. kubectl configured with cluster access

Step 1: Update Secrets (CRITICAL)

# Update PostgreSQL password
vim platform/apps/postgresql/db-backstage-credentials.yaml

# Update Backstage integration secrets
vim platform/apps/backstage/secrets.yaml

Step 2: Deploy via ArgoCD

# Apply bootstrap application (App-of-Apps pattern)
kubectl apply -f platform/bootstrap/app-of-apps.yaml

# Wait for sync
argocd app wait platform-bootstrap --sync

Step 3: Monitor Deployment

# Watch pods come up
watch kubectl get pods -n fawkes

# Check ArgoCD applications
argocd app list

# Verify PostgreSQL cluster
kubectl get cluster -n fawkes db-backstage-dev

Step 4: Access Backstage

# Local development (port-forward)
kubectl port-forward -n fawkes svc/backstage 7007:7007
# Access: http://localhost:7007

# Production (ingress)
# Access: https://backstage.fawkes.idp

Step 5: Verify Catalog

  1. Login with GitHub OAuth
  2. Navigate to "Catalog"
  3. Verify all platform components are listed
  4. Test creating a service from a template
