Issue #92: Design Tool Integration - Implementation Summary

Status: ✅ Complete Date: December 24, 2024 Milestone: M3.2 Priority: P2

Overview

Successfully integrated Penpot, an open-source design and prototyping platform, into the Fawkes Internal Delivery Platform. This integration enables seamless design-to-code workflows with Backstage plugin support for viewing designs inline.

What Was Implemented

1. Penpot Deployment ✅

Created complete Kubernetes deployment for Penpot with the following components:

Penpot Backend (penpotapp/backend:2.0.3)
Main application server and API
Resource limits: 1 CPU core, 2Gi RAM
Health checks configured
Penpot Frontend (penpotapp/frontend:2.0.3)
Web-based UI for designers
2 replicas for high availability
Resource limits: 500m CPU, 512Mi RAM
Penpot Exporter (penpotapp/exporter:2.0.3)
Asset export service (SVG, PNG, PDF)
Resource limits: 500m CPU, 1Gi RAM
Redis (redis:7.2-alpine)
Session and cache management
Resource limits: 200m CPU, 256Mi RAM
PostgreSQL Database
Dedicated database cluster for Penpot
Managed by CloudNativePG operator
10Gi storage allocation

Files Created:

/platform/apps/penpot/deployment.yaml - All Kubernetes resources
/platform/apps/penpot/README.md - Deployment documentation
/platform/apps/penpot-application.yaml - ArgoCD application manifest
/platform/apps/postgresql/db-penpot-cluster.yaml - Database configuration

2. Backstage Integration ✅

Configured Backstage plugin for seamless design viewing:

Plugin Configuration:

Custom Penpot viewer plugin
Component mapping for Design System sync
Proxy endpoint: /penpot/api → http://penpot-backend.fawkes.svc:6060/api/

Component Annotations:

annotations:
  penpot.io/design-id: "project-id/file-id"
  penpot.io/design-page: "page-name"
  penpot.io/design-version: "v2.0"

Component Mapping:

10+ mapped components (Button, Input, Card, Alert, etc.)
Auto-validation of design token consistency
Warning system for unmapped components

Files Created:

/platform/apps/backstage/plugins/penpot-viewer.yaml - Plugin configuration and component mappings
Updated /platform/apps/backstage/app-config.yaml - Added Penpot proxy endpoint

3. Documentation ✅

Created comprehensive documentation for the entire workflow:

Design-to-Code Workflow (13KB):

7-phase workflow from design to deployment
Step-by-step guides for designers, developers, and QA
Tools reference and troubleshooting guides
Best practices and metrics tracking

Access Controls (10KB):

Authentication methods (local, OAuth, LDAP/SAML)
Role-based access control (Owner, Admin, Editor, Viewer)
Security best practices and compliance guidance
Monitoring and alerting configuration

Component Library Sync (12KB):

Design token validation
Component mapping logic
Troubleshooting and best practices

Files Created:

/docs/how-to/design-to-code-workflow.md
/docs/how-to/penpot-access-controls.md
/docs/how-to/component-library-sync.md

4. Testing ✅

Created comprehensive BDD test coverage:

Test Scenarios (15 scenarios):

Penpot deployment and accessibility
Database configuration
Persistent storage
Ingress configuration
Backstage plugin configuration
Component annotations
Component mapping
Workflow documentation
ArgoCD management
Resource limits
Health checks
Asset export functionality
Access controls
End-to-end workflow
Acceptance criteria validation

Files Created:

/tests/bdd/features/penpot-integration.feature
Updated /scripts/validate-at-e3-004.sh with 7 additional Penpot checks

Technical Decisions

Why Penpot Over Figma?

Open Source: Full control, no vendor lock-in
Self-Hosted: Data stays within cluster, better for compliance
Cost: No per-seat licensing costs
API-First: Better automation capabilities
GitOps-Friendly: Kubernetes-native deployment
SVG-Based: Web standards, better developer handoff

Architecture Highlights

Microservices Design: Separate containers for backend, frontend, exporter
High Availability: Multiple replicas for frontend
Resource Optimization: Configured CPU/memory limits for 70% target
Health Monitoring: Liveness and readiness probes
GitOps: ArgoCD for declarative deployment
Observability: Integration with platform monitoring

Resource Usage

Estimated resource requirements:

Component	CPU (Request/Limit)	Memory (Request/Limit)
Backend	200m / 1000m	512Mi / 2Gi
Frontend	100m / 500m	256Mi / 512Mi
Exporter	100m / 500m	256Mi / 1Gi
Redis	50m / 200m	128Mi / 256Mi
PostgreSQL	200m / 1000m	512Mi / 2Gi
Total	650m / 3200m	1664Mi / 6Gi

Next Steps (Post-Deployment)

Deploy to Cluster

kubectl apply -f platform/apps/penpot-application.yaml

Verify Deployment

kubectl get pods -n fawkes -l app=penpot
kubectl logs -n fawkes -l component=backend

Initial Setup
Access Penpot at https://penpot.fawkes.local
Create admin user on first login
Create "Fawkes Platform" team
Invite team members
Configure Component Library
Create Penpot project for Design System
Tag with design-system label
Build components using design tokens
Test Backstage Integration
Add penpot.io/design-id annotation to a component
Verify design appears in Backstage "Design" tab
Test component mapping validation
Set Up Sync Job
Configure Jenkins job for hourly sync
Set up Mattermost notifications
Test end-to-end sync process

Known Limitations

OAuth Integration: Planned for future, currently using local auth
Webhooks: No real-time sync, runs hourly via Jenkins
Visual Regression: Manual comparison, automated testing planned
Bidirectional Sync: Currently one-way (Penpot → Design System)

Dependencies Met

✅ Issue #91: Create Design System Component Library (completed)
✅ Design System with 40+ components available
✅ Storybook deployed and accessible

Blocks Unblocked

✅ Issue #93: Deploy Storybook for Component Documentation (can now proceed)
Design references can be embedded in Storybook via plugin
