Demo Script: Open Service Portal Platform MVP

Date: August 29, 2025
Duration: 30-45 minutes
Audience: Technical stakeholders, Platform team, DevOps engineers

Executive Summary​

In the past two weeks, we've transformed the Open Service Portal from a proof-of-concept into a functional MVP that combines Backstage's developer portal capabilities with Crossplane's infrastructure automation, creating a true self-service platform for developers.

Key Achievements​

  • ✅ Full GitOps workflow with Flux (catalog → deploy → monitor)
  • ✅ 10+ ready-to-use templates (5 infrastructure, 6+ services)
  • ✅ Automated XRD form generation with Kubernetes Ingestor
  • ✅ Production-ready Cloudflare DNS integration
  • ✅ Unified setup script for any Kubernetes distribution
  • ✅ Namespace provisioning with quotas, policies, and RBAC
  • ✅ GitHub Container Registry packaging for versioned releases

Demo Flow​

Part 1: Platform Architecture Overview (5 min)​

1.1 Repository Structure​

# Show the workspace structure
cd /Users/felix/work/open-service-portal/portal-workspace
tree -L 1 -d

# Explain the repository types:
# - app-portal:        Backstage application
# - catalog:           XRD/Composition definitions (what CAN be created)
# - catalog-orders:    XR instances (what HAS been created)
# - template-*:        Crossplane infrastructure templates
# - service-*:         Backstage service scaffolding templates

Talking Points:

  • Separation of concerns: definitions vs instances
  • GitOps-driven deployment via Flux
  • Template marketplace concept

1.2 GitOps Workflow Visualization​

Part 2: Platform Setup - Zero to Platform in 5 Minutes (10 min)​

2.1 Unified Cluster Setup​

# Show the setup script capabilities
cat scripts/setup-cluster.sh | grep "^install_" | head -10

# Run the setup (or show it's already done)
./scripts/setup-cluster.sh

# Show what was installed
kubectl get pods -A | grep -E "flux|crossplane|ingress"

Key Points:

  • Works with ANY Kubernetes distribution (Kind, Rancher, EKS, GKE, AKS)
  • Installs complete platform stack in one command
  • Includes NGINX Ingress, Flux, Crossplane v2, all providers

2.2 Environment Switching​

# Show environment configuration capabilities
./scripts/config-local.sh        # Local development
# ./scripts/config-openportal.sh  # Production (OpenPortal)

# Show the generated Backstage config
cat app-portal/app-config.local.yaml | head -20

Part 3: Template Marketplace - What Can We Build? (10 min)​

3.1 Infrastructure Templates (Crossplane)​

# Show available XRDs
kubectl get xrd | grep openportal

# Show a template definition
cat template-whoami/xrd.yaml | head -50

Live Demo - Browse Templates:

  1. Open http://localhost:3000/create
  2. Show the auto-generated forms from XRDs:
    • Namespace - Full namespace provisioning with quotas & RBAC
    • DNSRecord - Mock DNS for testing
    • CloudflareDNSRecord - Real DNS management
    • WhoAmIApp - Demo application with auto-DNS
    • WhoAmIService - Composite (App + DNS)

3.2 Service Templates (Backstage Scaffolder)​

# Show service templates
ls -la service-*-template/

Template Categories:

  • service-nodejs-template - Express.js microservices
  • service-mongodb-template - Database services
  • service-firewall-template - Network security rules
  • service-cluster-template - Full cluster provisioning

Part 4: Live Demo - Create Real Infrastructure (10 min)​

  3. Fill the form: 
    name: demo-namespace
    team: platform-team
    environment: dev
    quotas:
      enabled: true
      limits:
        cpu: "10"
        memory: "16Gi"
  4. CREATE and watch GitOps deploy it
  5. Verify: 
    kubectl get namespace demo-namespace
    kubectl get resourcequota -n demo-namespace

4.2 Create a WhoAmI Application​

  1. Navigate to http://localhost:3000/create
  2. Select "WhoAmIApp" template
  3. Fill the form: 
    name: demo-app-aug29
    namespace: demo-namespace  # Use our new namespace!
    replicas: 2
  4. Show the publish step:
    • Target repo: catalog-orders (auto-configured!)
    • Branch: main
  5. CREATE the application

4.2 Watch the GitOps Magic​

# Terminal 1: Check GitHub
cd ../catalog-orders
git pull origin main
ls -la
cat */demo-app-aug29.yaml  # Show the generated XR

# Terminal 2: Watch Flux sync
kubectl get gitrepository,kustomization -n flux-system | grep catalog-orders
flux logs --follow --tail=10

# Terminal 3: See the XR created
kubectl get whoamiapps -A
kubectl get whoamiapp demo-app-aug29 -n default -o yaml | head -30

# Terminal 4: Check actual deployment
kubectl get pods -n default | grep demo-app
kubectl get ingress -n default

4.3 Access the Application​

# Get the URL (if DNS is configured)
kubectl get whoamiapp demo-app-aug29 -n default -o jsonpath='{.status.domain}'

# Or port-forward for local access
kubectl port-forward -n default svc/demo-app-aug29 8080:80
# Open http://localhost:8080

Part 5: Advanced Features Showcase (5 min)​

# Show how forms are generated from XRDs
kubectl describe xrd whoamiapps.openportal.dev | grep -A20 "Spec:"

# In Backstage, show the corresponding form fields
# Each OpenAPI schema property becomes a form field!

5.2 Template Versioning​

# Show version labels

Q&A Topics​

Anticipated Questions:​

Q: How does this compare to other platforms? A: We combine the best of both worlds:

  • Backstage's superior UX and extensibility
  • Crossplane's cloud-native infrastructure management
  • GitOps for compliance and auditability

Q: What's the learning curve for developers? A: Near zero - they just fill forms. Platform team handles the complexity.

Q: Can we integrate with existing tools? A: Yes - Backstage has 100+ plugins, Crossplane supports any API

Q: What about disaster recovery? A: Everything in Git = instant recovery. Flux ensures desired state.

Q: Performance at scale? A: Proven architectures - both Backstage and Crossplane run at massive scale

Speaker Notes​

Energy & Pacing​

  • Start high energy - this is exciting technology!
  • Slow down for technical deep dives
  • Speed up during navigation/clicking
  • Leave time for questions after each section

Key Messages to Emphasize​

  1. Speed of Development: 2 weeks to MVP
  2. Developer Experience: Self-service, no tickets
  3. Production Ready: Security, GitOps, monitoring built-in
  4. Extensibility: Easy to add new templates and providers

Potential Objections & Responses​

  • "Too complex" → Show the simple developer experience
  • "Another tool to learn" → It replaces multiple tools
  • "What about our existing setup?" → It integrates, doesn't replace

Technical Issues Backup​

If demos fail:

  1. Have screenshots ready
  2. Show the generated YAML files
  3. Explain the concept without live demo
  4. Reference the recorded demo video (prepare one)

Demo Success Criteria:

  • Audience understands the platform value
  • At least one "wow" moment (auto-form generation)
  • Clear next steps identified
  • Stakeholder buy-in achieved

Good luck with the demo! 🚀
