🚀 Deployment Instructions

Quick Deploy (Automated)

# 1. Set environment variables
export GCP_PROJECT_ID="your-project-id"
export GCP_REGION="us-central1"
export GKE_CLUSTER="coditect-cluster"

  --from-literal=DJANGO_SECRET_KEY="$(python -c 'import secrets; print(secrets.token_urlsafe(50))')" \
  --from-literal=DB_USER="django" \
  --from-literal=DB_PASSWORD="$(openssl rand -base64 32)" \
  --from-literal=JWT_SECRET_KEY="$(python -c 'import secrets; print(secrets.token_urlsafe(50))')" \
  -n coditect-backend

# 3. Apply manifests
kubectl apply -f k8s/

# 4. Run migrations
POD=$(kubectl get pods -n coditect-backend -l app=django-backend -o jsonpath='{.items[0].metadata.name}')
kubectl exec -it ${POD} -n coditect-backend -- python manage.py migrate

1. Build Verification

# Build Docker image
cd /Users/halcasteel/PROJECTS/coditect-rollout-master/submodules/cloud/coditect-cloud-backend
docker build -t coditect-django-backend:test .

# Expected output:
# ✅ Successfully built multi-stage image
# ✅ Image size < 500 MB
# ✅ Health check configured

2. Configuration Verification

# Validate Kubernetes manifests
kubectl apply --dry-run=client -f k8s/

# Expected output:
# ✅ All manifests valid
# ✅ No syntax errors
# ✅ Resource limits defined

3. Deployment Verification

After deployment, verify:

# Pod status
kubectl get pods -n coditect-backend
# Expected: 3/3 Running pods

# Service endpoints
kubectl get endpoints django-backend-service -n coditect-backend
# Expected: 3 endpoints listed

# Health checks
curl https://api.coditect.com/api/v1/health/
# Expected: {"status": "healthy", ...}

curl https://api.coditect.com/api/v1/health/ready/
# Expected: {"status": "ready", ...}

4. Performance Verification

# Test response time
time curl https://api.coditect.com/api/v1/health/
# Expected: < 3 seconds (target: < 5s)

# Check resource usage
kubectl top pods -n coditect-backend
# Expected: Within defined limits

# Verify auto-scaling
kubectl get hpa django-backend-hpa -n coditect-backend
# Expected: TARGETS showing current metrics

- Replace INSTANCE_NAME in deployment.yaml
- Update domain in ingress.yaml (if different)
DNS Configuration
- Point api.coditect.com to ingress IP
- Verify DNS propagation
- Test HTTPS access

Post-Deployment

Monitoring Setup
- Configure Prometheus metrics scraping
- Set up Grafana dashboards
- Configure alerting rules
- Set up log aggregation
Testing
- Load testing with realistic traffic
- Auto-scaling verification
- Rollback procedure testing
- Disaster recovery drill
Documentation

- Create team onboarding guide

🐛 Known Limitations

Secret Management: Uses Kubernetes secrets (consider migrating to GCP Secret Manager for enhanced security)
Static Files: Served by Django (consider CDN for production at scale)
Media Files: Stored in container (use GCS for persistent storage)
Database Migrations: Manual execution required (consider automation in CI/CD)
Session Storage: In-database (consider Redis for better performance)
