Cloudflare
AWS Route53
DigitalOcean
Many others via Traefik

Troubleshooting:

Cloudflare proxy can interfere with LE validation
IPv4/IPv6 both must be correctly configured
Ports 80 and 443 must be accessible from internet

Deployment Strategies

Rolling Updates (Zero-Downtime):

New container starts while old continues running
Health check validates new container
Old container stops only when new is healthy
Requirements:
- Valid health check configured
- Default container naming (no custom names)
- No host port mapping conflicts
- Not supported for Docker Compose deployments

Rollback Capabilities:

Rollback to previous versions
Currently: Only local Docker images supported
One-click rollback via UI
Keeps recent deployment history

Blue-Green Deployment:

❌ Not natively supported (feature request)
Can implement manually with Traefik configuration
Community workarounds available
Rolling updates serve similar purpose

Monitoring & Logging

Built-in Features:

Real-time container logs (streaming)
Resource usage metrics (basic)
Deployment history
Service health checks

Prometheus & Grafana Integration:

One-click Grafana deployment
One-click Prometheus deployment
Community guides for cAdvisor (container metrics)
Node Exporter for system metrics
Grafana dashboards for visualization

Logging Stack (Recommended Setup):

Loki for log aggregation
FluentBit as log shipper
Grafana for log visualization
Community step-by-step guides available

External Monitoring:

Uptime monitoring (Uptime Kuma one-click service)
Alerting via email, Discord, Telegram, Slack, PagerDuty
Custom health check endpoints
Webhook notifications for deployment events

Scalability

Vertical Scaling:

✅ Easy to resize server resources
✅ Zero downtime with Hetzner live resize
✅ Automatic resource detection

Horizontal Scaling:

⚠️ Multiple server support (experimental)
⚠️ Docker Swarm support (limited)
❌ No built-in load balancing
❌ Container naming prevents replicas

Multi-Server Deployment:

Requires Docker Registry (push built images)
Can manage multiple separate servers
Each app can target different servers
No automatic traffic distribution

Docker Swarm Limitations:

Requires 3+ servers minimum
Same architecture (ARM or AMD64)
Coolify built on Docker Compose/bridge networks
Swarm integration is architectural challenge
Community reports predefined container names prevent true scaling

Recommended Scaling Strategy:

Start with single powerful server (CAX31/CPX31)
Separate concerns (apps on one server, databases on another)
Use external load balancer if needed
For true HA, consider managed Kubernetes or multiple Coolify instances

2. Comparative Analysis

2.4 GitHub Actions Integration

Coolify Integration Patterns

Pattern 1: Direct Git Integration (Simplest)

Developer → Git Push → Coolify watches repo → Auto-deploy

✅ Zero CI/CD configuration
✅ Works out of the box
❌ No automated tests before deploy
❌ Not suitable for monorepos

Pattern 2: GitHub Actions + Coolify Webhook (Recommended)

Developer → Git Push → GitHub Actions:
  1. Run tests (Jest, Vitest, Playwright)
  2. Build Docker image
  3. Push to Docker registry
  4. Trigger Coolify webhook
→ Coolify pulls image and deploys

✅ Automated testing before deployment
✅ Build matrix (multiple Node versions)
✅ Monorepo support (Turborepo --filter)
✅ Control over deployment conditions
⚠️ Requires Docker registry (Docker Hub, GitHub Container Registry)

Pattern 3: GitHub Actions + Coolify API

Developer → Git Push → GitHub Actions:
  1. Run tests
  2. Build artifacts
  3. Call Coolify API to deploy
→ Coolify builds and deploys

✅ Full API control
✅ Can deploy multiple apps from monorepo
✅ Custom deployment logic
⚠️ More complex setup

Monorepo-Specific Strategy (For manacore-monorepo)

Turborepo + GitHub Actions + Coolify

# .github/workflows/deploy.yml
name: Deploy to Coolify

on:
  push:
    branches: [main]
  pull_request:

jobs:
  test-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: 'pnpm'

      - name: Install dependencies
        run: pnpm install --frozen-lockfile

      - name: Run tests
        run: pnpm run test

      - name: Build affected apps
        run: npx turbo run build --filter=[HEAD^1]

      - name: Deploy to Coolify
        if: github.ref == 'refs/heads/main'
        run: |
          # Trigger Coolify webhook for each changed app
          curl -X POST ${{ secrets.COOLIFY_WEBHOOK_MEMORO }}
          curl -X POST ${{ secrets.COOLIFY_WEBHOOK_CHAT }}

Benefits for Your Monorepo:

Only deploys changed applications (Turborepo --filter)
Runs all tests before any deployment
Parallel builds (Turborepo caching)
Each product can have separate Coolify webhook
PR preview environments for testing

Automated Testing Requirements

Current State (from CLAUDE.md):

~25 test files total (sparse coverage)
No pre-commit hooks (except maerchenzauber SSH URL fixer)
No CI pipeline for tests

Recommended Implementation:

Unit Tests: Vitest for shared packages and backends
Integration Tests: Supertest for NestJS APIs
E2E Tests: Playwright for SvelteKit web apps
Pre-commit: Husky + lint-staged (format + lint)
CI Pipeline: GitHub Actions (lint, format, type-check, test)
Deployment Gate: Tests must pass before Coolify webhook

Phased Rollout:

Phase 1: Add GitHub Actions for linting and type-checking (week 1)
Phase 2: Add unit tests for critical paths (weeks 2-4)
Phase 3: Gate deployments on test success (week 5)
Phase 4: Add E2E tests for key user flows (weeks 6-12)

Coolify Configuration (Per App)

For each application in Coolify:

Source Type: Dockerfile
Build Pack: None (custom Dockerfile)
Dockerfile Location: /apps/memoro/apps/backend/Dockerfile

Build Arguments:

APP_PATH=apps/memoro/apps/backend
APP_PACKAGE=@memoro/backend

Environment Variables (from centralized .env.development):

NODE_ENV=production
PORT=3000
SUPABASE_URL=${SUPABASE_URL}
SUPABASE_SERVICE_ROLE_KEY=${SUPABASE_SERVICE_ROLE_KEY}
MIDDLEWARE_API_URL=${MIDDLEWARE_API_URL}

Health Check: /health endpoint (NestJS apps should implement)
Domains: memoro-api.yourdomain.com

3.3 Environment Variable Strategy

Centralized Development (Current Setup)

From your CLAUDE.md:

.env.development is the single source of truth
scripts/generate-env.mjs generates platform-specific .env files
Prefixes: EXPO_PUBLIC_*, PUBLIC_*, none (backend)

Production Strategy with Coolify

Option 1: Coolify Environment Variables (Recommended)

Coolify stores environment variables securely and injects them at runtime.

For each Coolify app:
1. Navigate to app > Configuration > Environment Variables
2. Add variables (encrypted at rest):
   - NODE_ENV=production
   - SUPABASE_URL=https://xxx.supabase.co
   - SUPABASE_SERVICE_ROLE_KEY=***
   - MIDDLEWARE_API_URL=https://auth.yourdomain.com
3. Check "Build Time" for PUBLIC_* variables (SvelteKit needs at build)
4. Leave unchecked for runtime secrets (database passwords)

Option 2: Docker Secrets (Advanced)

For sensitive production data:

# Create Docker secrets
echo "super_secret_key" | docker secret create db_password -

# Reference in docker-compose.yml
services:
  backend:
    secrets:
      - db_password
    environment:
      DB_PASSWORD_FILE: /run/secrets/db_password

Option 3: External Secrets Manager

For enterprise requirements:

HashiCorp Vault
AWS Secrets Manager
Google Secret Manager
Doppler
Infisical (open-source)

Migration Path

Development: Keep using .env.development + generate-env.mjs
Staging: Replicate .env.development variables in Coolify (staging environment)
Production: Use production values in Coolify, never commit to git
CI/CD: GitHub Actions reads from Coolify API or uses GitHub Secrets

3.4 Database Migration Strategy

Supabase Migrations (Recommended for Production)

From search results on Supabase best practices:

Workflow:

Local Development:
  1. Make schema changes via Supabase CLI or Dashboard
  2. Generate migration: `supabase db diff -f migration_name`
  3. Test locally: `supabase db reset`
  4. Commit migration to git

Staging Deployment:
  5. GitHub Actions runs on push to `staging` branch
  6. `supabase db push --db-url $STAGING_DB_URL`
  7. Run integration tests

Production Deployment:
  8. Merge to `main` with approval
  9. GitHub Actions runs `supabase db push --db-url $PRODUCTION_DB_URL`
  10. Migration applied via CI (not from local machine)

GitHub Actions Example:

name: Deploy Database Migrations

on:
  push:
    branches: [main]
    paths:
      - 'supabase/migrations/**'

jobs:
  deploy-migrations:
    runs-on: ubuntu-latest
    environment: production  # Requires approval
    steps:
      - uses: actions/checkout@v4

      - uses: supabase/setup-cli@v1
        with:
          version: latest

      - name: Run migrations
        run: supabase db push --db-url ${{ secrets.PRODUCTION_DB_URL }}

      - name: Notify team
        if: failure()
        run: |
          curl -X POST ${{ secrets.SLACK_WEBHOOK }} \
            -d '{"text": "🚨 Database migration failed!"}'

Safety Measures:

✅ Always test in staging first
✅ Write rollback migrations
✅ Backup before production migration
✅ Use approval workflows in GitHub Actions
✅ Never run migrations from local machine in production
✅ Use database branching for risky migrations (Supabase feature)

Self-Hosted PostgreSQL (If not using Supabase)

Migration Tools:

Drizzle ORM (already used in uload project)
Prisma (popular alternative)
TypeORM (if using NestJS)
raw SQL migrations via CI/CD

Example with Drizzle:

// apps/chat/apps/backend/src/db/migrations/0001_initial.sql
CREATE TABLE users (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  email TEXT UNIQUE NOT NULL,
  created_at TIMESTAMP DEFAULT NOW()
);

// Run via Coolify (exec into container)
pnpm drizzle-kit push:pg --config=drizzle.config.ts

Automated Migration Deployment:

# In Coolify, configure post-deployment script
#!/bin/bash
cd /app
node -e "
  const { migrate } = require('drizzle-orm/node-postgres/migrator');
  const db = require('./src/db');
  migrate(db, { migrationsFolder: './src/db/migrations' })
    .then(() => console.log('Migrations complete'))
    .catch(err => { console.error(err); process.exit(1); });
"

3.5 Mobile App Backend Considerations

Expo Mobile Apps (React Native)

Your mobile apps (memoro, picture, chat, maerchenzauber, manadeck, manacore) have special requirements:

What Gets Deployed:

❌ Mobile app itself (deployed to App Store/Play Store, not Coolify)
✅ Backend API (NestJS on Coolify)
✅ Web companion app (SvelteKit on Coolify)
✅ Landing page (Astro on Coolify)

API Requirements:

HTTPS: Required for iOS App Transport Security (ATS)
- ✅ Coolify provides automatic SSL via Let's Encrypt
Domain: Proper domain (not IP address)
- Example: api.memoro.app, chat-api.manacore.app
CORS: Configure for mobile app and web app origins
Rate Limiting: Protect APIs from abuse
Health Checks: /health endpoint for Coolify monitoring

Environment Variables (Expo Apps):

// apps/memoro/apps/mobile/.env
EXPO_PUBLIC_API_URL=https://api.memoro.app
EXPO_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
EXPO_PUBLIC_SUPABASE_ANON_KEY=eyJhbGc...
EXPO_PUBLIC_MIDDLEWARE_API_URL=https://auth.manacore.app

Build Process:

# Local development
pnpm run dev:memoro:mobile  # Expo dev server

# Build for production (EAS Build)
cd apps/memoro/apps/mobile
eas build --platform all --profile production

# Update API URL before build
# apps/memoro/apps/mobile/app.config.ts
export default {
  extra: {
    apiUrl: process.env.EXPO_PUBLIC_API_URL || 'https://api.memoro.app',
  },
};

Deployment Checklist:

✅ Deploy backend API to Coolify (NestJS)
✅ Verify API accessible via HTTPS domain
✅ Test API endpoints with Postman/Insomnia
✅ Update mobile app EXPO_PUBLIC_API_URL to production domain
✅ Build mobile app with EAS Build
✅ Submit to App Store / Play Store

Scalability for Mobile Apps:

Authentication: Supabase Auth (already implemented via middleware)
Real-time: Supabase Realtime (WebSocket)
Push Notifications: Expo Push Notifications (free for <100k/month)
Analytics: PostHog, Mixpanel, or Amplitude
Error Tracking: Sentry (has free tier)
API Versioning: /v1/, /v2/ paths for backward compatibility

Load Balancing (if needed):

Mobile App → Cloudflare (CDN) → Load Balancer → Multiple API containers

Coolify doesn't have built-in load balancing, but you can:

Use Cloudflare Load Balancing ($5/month + $0.50/10k requests)
Deploy HAProxy in front of Coolify apps
Use Hetzner Load Balancer (€5.39/month)

Cloudflare Pro	Cloudflare	$20/month	WAF, advanced caching
Sentry (Errors)	Sentry	Free - $26/month	Error tracking
PostHog (Analytics)	PostHog	Free - $20/month	Product analytics
Uptime monitoring	UptimeRobot	Free - $7/month	External uptime checks

Total with Add-ons: $50-100/month

5.2 Comparison with Alternatives

Solution	Monthly Cost	Setup Time	Maintenance	Scalability
Coolify + Hetzner	$50	2-3 weeks	Low-Medium	Good
Vercel + Netlify + Heroku	$150-300	1 week	Minimal	Excellent
AWS	$250-500	3-4 weeks	Medium	Excellent
DigitalOcean App Platform	$120-250	2 weeks	Low	Good
Google Cloud Run	$100-300	2 weeks	Low	Excellent
Azure	$200-400	3 weeks	Medium	Excellent

5.3 Cost Breakdown by Product

Per Product Cost (Coolify + Hetzner):

Assuming 6 products sharing infrastructure:

Infrastructure: $50/month ÷ 6 = $8.33/product
Supabase (if used): $25/month per project (free tier may suffice initially)
Expo EAS Build: Free tier (10 builds/month) or $29/month unlimited
Domain: $10-15/year (~$1/month)

Total per product: $9-60/month depending on services used

Comparison to Separate PaaS Deployments:

Coolify: $8.33/product (shared infrastructure)
Vercel + Heroku: $25-50/product (dedicated resources)
Savings: 65-83% reduction

5.4 Cost Optimization Strategies

Immediate Savings:

Use Supabase free tier ($0 vs $25/project for managed DB)
- Up to 500 MB database
- 1 GB file storage
- 50,000 monthly active users
Use Cloudflare free tier ($0 vs $20/month for CDN)
Share databases across products (if architecturally feasible)
Use Expo free tier (10 builds/month sufficient for early stage)

Long-term Optimizations:

Reserved instances (Hetzner doesn't have this, but commitment is implicit)
Spot instances (not available on Hetzner, already cheapest)
Right-sizing (monitor resource usage, downsize if possible)
CDN offloading (move static assets to Cloudflare, reduce server load)
Database optimization (indexes, query optimization, reduce DB size)

Breakeven Analysis:

Monthly Spend	Break-even vs PaaS	Savings/Year
$50	$150 (3x cheaper)	$1,200
$100	$300 (3x cheaper)	$2,400
$200	$600 (3x cheaper)	$4,800

At your scale (6 products), you'd save $1,200-2,400/year compared to traditional PaaS.

6. Risk Assessment & Mitigation

6.1 Identified Risks

Infrastructure Risks:

Risk	Likelihood	Impact	Mitigation
Server failure	Medium	High	Automated backups, snapshots, multi-server setup
Data loss	Low	Critical	Automated backups to Object Storage, different region
DDoS attack	Medium	Medium	Cloudflare protection (free), Hetzner DDoS mitigation
Account compromise	Low	Critical	2FA, SSH keys only, IP whitelisting
Accidental deletion	Medium	High	Coolify resource locks, confirmation dialogs

Operational Risks:

Risk	Likelihood	Impact	Mitigation
Failed deployment	Medium	Medium	Rollback capability, health checks, staging environment
Database migration failure	Medium	High	Test in staging, rollback scripts, backups before migration
Configuration drift	High	Low	Infrastructure as code (Terraform), version control
Lack of monitoring	High	High	Comprehensive monitoring stack (Grafana, Prometheus, Loki)
Knowledge concentration	High	Medium	Documentation, runbooks, team training

Vendor Risks:

Risk	Likelihood	Impact	Mitigation
Hetzner outage	Low	High	Multi-region deployment (future), status page monitoring
Coolify development stops	Low	Medium	Open-source (can fork), active community
Supabase pricing increase	Medium	Medium	Self-hosted PostgreSQL fallback plan
Docker Hub rate limits	Medium	Low	Use GitHub Container Registry (free, unlimited)

6.2 Mitigation Strategies

High-Priority Mitigations (Implement in Phase 1-3):

Automated Backups:

# Daily database backup cron
0 2 * * * docker exec postgres pg_dump -U postgres > /backups/db_$(date +\%Y\%m\%d).sql
# Upload to Object Storage
0 3 * * * rclone sync /backups hetzner-s3:backups

Health Checks:

// apps/*/apps/backend/src/health/health.controller.ts
@Get('/health')
async health() {
  return {
    status: 'ok',
    timestamp: new Date(),
    database: await this.checkDatabase(),
    memory: process.memoryUsage(),
  };
}

Deployment Gates:

# .github/workflows/deploy.yml
- name: Run tests
  run: pnpm test
- name: Deploy only if tests pass
  if: success()
  run: curl -X POST $COOLIFY_WEBHOOK

Medium-Priority Mitigations (Implement in Phase 4-6):

Monitoring Alerts:
- CPU > 80% for 5 minutes → Alert team
- Disk > 90% → Alert + auto-cleanup logs
- API response time > 2s → Investigate performance
- Failed health checks → Restart container
Staging Environment:
- Separate Hetzner server (CAX11, €3.79/month)
- Deploy all changes to staging first
- Run integration tests
- Manual approval before production
Disaster Recovery Plan:
- Document recovery procedures
- Quarterly disaster recovery drills
- Test restoring from backups
- Keep offline copy of critical credentials

Low-Priority Mitigations (Implement in Phase 7+):

Multi-Region Deployment:
- Hetzner Germany (primary) + Hetzner US (failover)
- DNS failover with Cloudflare
- Costs: +$50-100/month
Advanced Security:
- Intrusion detection (AIDE, OSSEC)
- Web Application Firewall (Cloudflare WAF)
- Security scanning (Trivy for containers)

7.2 Recommendation

Primary Recommendation: Coolify + Hetzner

Justification:

✅ Highest weighted score (8.40/10)
✅ 90% cost reduction vs traditional PaaS ($50/month vs $150-300/month)
✅ Excellent developer experience (self-hosted Heroku alternative)
✅ Native CI/CD integration with GitHub Actions
✅ Supports all your stack components (NestJS, SvelteKit, Astro, Expo backends)
✅ Scales with your growth (can add servers as needed)
✅ Low vendor lock-in (open-source, can migrate if needed)
✅ Active community (Coolify Discord has 10k+ members)

Best For:

Early-stage to mid-stage startups (your current stage)
Teams of 1-10 developers
Budget-conscious projects needing professional infrastructure
Monorepo architectures with multiple apps
Teams comfortable with Docker basics

Secondary Recommendation: Traditional PaaS (Vercel/Netlify/Railway)

When to Choose:

You secure significant funding (>$500k)
Team size grows to 20+ developers
Zero tolerance for infrastructure management
Need enterprise-grade SLAs and support

Not Recommended: Managed Kubernetes or Hetzner Only

Reasons:

Kubernetes: Overkill for 6 applications, steep learning curve, high maintenance
Hetzner Only: Requires extensive DevOps expertise, no PaaS layer
