Status: ⏳ PENDING CLEANUP (after 48h stability)

V5 API (PRODUCTION - ACTIVE):

Deployment: coditect-api-v5
Pods: 3/3 Running (11 days old)
Image: Rust backend with Actix-web + FoundationDB
Endpoint: api.coditect.ai
Status: ✅ HEALTHY

Ingress Routing

Current Configuration (coditect-production-ingress):

Host: coditect.ai
  Path: /api/v5/* → coditect-combined-service-hybrid:80
  Path: /* → coditect-combined-service-hybrid:80

Host: www.coditect.ai
  Path: /* → coditect-combined-service-hybrid:80

Host: api.coditect.ai
  Path: /* → coditect-api-v5-service:80

Status: ✅ All routes HEALTHY, backends responding 200 OK

Storage (PVCs)

Hybrid Deployment (ACTIVE):

workspace-coditect-combined-hybrid-0/1/2: 10GB each (30GB total)

Status: ✅ COMPLETE

Phase 2: Update Hybrid Pods to Production Image (Completed 2025-10-29 06:01 UTC)

Objective: Update hybrid pods from testing image (904176d4) to production image (67f9cde3)

Commands Executed:

# Get current production image
kubectl get statefulset coditect-combined -n coditect-app -o jsonpath='{.spec.template.spec.containers[0].image}'
# Result: 67f9cde3-c8d7-452b-b858-6b74968835e9

# Update hybrid to same image
kubectl set image statefulset/coditect-combined-hybrid \
  combined=us-central1-docker.pkg.dev/serene-voltage-464305-n2/coditect/coditect-combined:67f9cde3-c8d7-452b-b858-6b74968835e9 \
  -n coditect-app

# Monitor rollout
kubectl rollout status statefulset/coditect-combined-hybrid -n coditect-app --timeout=5m

Result:

All 3 pods updated sequentially (StatefulSet pattern: pod-2 → pod-1 → pod-0)
coditect-combined-hybrid-0: Running, 67f9cde3
coditect-combined-hybrid-1: Running, 67f9cde3
coditect-combined-hybrid-2: Running, 67f9cde3

Status: ✅ COMPLETE

Phase 3: Update Ingress Routing (Completed 2025-10-29 06:08 UTC)

Objective: Switch production traffic from standard to hybrid service

Commands Executed:

# Update coditect.ai paths (2 paths: /api/v5 and /)
kubectl patch ingress coditect-production-ingress -n coditect-app --type=json -p='[
  {"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value": "coditect-combined-service-hybrid"},
  {"op": "replace", "path": "/spec/rules/0/http/paths/1/backend/service/name", "value": "coditect-combined-service-hybrid"}
]'

# Update www.coditect.ai path
kubectl patch ingress coditect-production-ingress -n coditect-app --type=json -p='[
  {"op": "replace", "path": "/spec/rules/1/http/paths/0/backend/service/name", "value": "coditect-combined-service-hybrid"}
]'

# Wait for GCP load balancer propagation
sleep 60

Verification:

# Test frontend
curl -I https://coditect.ai
# Result: HTTP/2 200 OK

# Test theia IDE
curl -I https://coditect.ai/theia
# Result: HTTP/2 200 OK

# Check backend health
kubectl describe ingress coditect-production-ingress -n coditect-app | grep -A 10 "Backends"
# Result: All backends HEALTHY

Downtime: <30 seconds (Ingress propagation only)

Status: ✅ COMPLETE

Phase 4: Verify Production Traffic (Completed 2025-10-29 06:08 UTC)

Verification Checklist:

✅ Hybrid pods receiving traffic (confirmed via logs)
✅ https://coditect.ai responding (200 OK)
✅ https://coditect.ai/theia loading theia IDE
✅ https://api.coditect.ai/health responding
✅ WebSocket connections working
✅ Pod resource usage normal (<1 GB RAM, <1 CPU)
✅ No errors in pod logs
✅ Ingress backends show HEALTHY
✅ Session affinity working (sticky sessions)

Status: ✅ COMPLETE

Phase 5: Cleanup Old Standard Deployment (PENDING - Wait 48h)

⚠️ DO NOT RUN IMMEDIATELY - Wait 24-48 hours for stability validation

Recommended Timeline:

24 hours (2025-10-30 06:08 UTC): Check for pod restarts, memory leaks, errors
48 hours (2025-10-31 06:08 UTC): If stable, scale down standard deployment
7 days (2025-11-05 06:08 UTC): Delete standard PVCs (point of no return)

Cleanup Commands (to run after 48h):

# Scale down standard deployment (keeps PVCs for safety)
kubectl scale statefulset/coditect-combined --replicas=0 -n coditect-app

# After 48 hours of stable hybrid operation:

# Delete standard StatefulSet (keeps PVCs for recovery)
kubectl delete statefulset/coditect-combined -n coditect-app

# Delete standard service
kubectl delete service/coditect-combined-service -n coditect-app

# After 7 days, delete PVCs (point of no return)
kubectl delete pvc workspace-coditect-combined-0 -n coditect-app
kubectl delete pvc workspace-coditect-combined-1 -n coditect-app
kubectl delete pvc workspace-coditect-combined-2 -n coditect-app
kubectl delete pvc theia-config-coditect-combined-0 -n coditect-app
kubectl delete pvc theia-config-coditect-combined-1 -n coditect-app
kubectl delete pvc theia-config-coditect-combined-2 -n coditect-app

Status: ⏳ PENDING (Current uptime: 30 minutes)

UI Optimization Work

Changes Made (Commit 9ea05dd - 2025-10-29 06:27 UTC)

Objective: Reduce header and footer heights to maximize vertical space for theia IDE

Files Modified:

src/components/header.tsx (line 66)
```
// BEFORE
h="56px"

// AFTER
h="40px"
```
Reduction: 16px (28% smaller)
src/components/footer.tsx (line 94)
```
// BEFORE
py={4}

// AFTER
py={2}
```
Reduction: ~16px (50% padding reduction)
src/components/layout.tsx (line 129)
```
// Updated comment
{/* Header (40px) */}
```

Total Savings: ~32px additional vertical space for theia IDE

Benefits:

✅ ~3-4% more IDE space on 1080p displays

Status: ⏳ NOT STARTED
Changes: Header/footer height reduction (commit 9ea05dd)
Target: Hybrid deployment
Estimated Duration: 10-12 minutes (E2_HIGHCPU_32)

Rollback Plan (If Issues Occur)

Quick Rollback (Ingress Only) - <2 Minutes:

# Switch Ingress back to standard service
kubectl patch ingress coditect-production-ingress -n coditect-app --type='json' \
  -p='[{"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value": "coditect-combined-service"}]'

# Verify
kubectl describe ingress coditect-production-ingress -n coditect-app

Full Rollback (Scale Up Standard) - 2-3 Minutes:

# If standard was scaled down
kubectl scale statefulset/coditect-combined --replicas=3 -n coditect-app

# Wait for pods ready
kubectl rollout status statefulset/coditect-combined -n coditect-app

# Switch Ingress back
kubectl patch ingress coditect-production-ingress -n coditect-app --type='json' \
  -p='[{"op": "replace", "path": "/spec/rules/0/http/paths/0/backend/service/name", "value": "coditect-combined-service"}]'

Risk Level: ✅ VERY LOW Confidence: HIGH (Standard deployment still available with 2/3 pods ready)

Monitoring & Validation

24-Hour Post-Migration Checklist

Metrics to Monitor (Until 2025-10-30 06:08 UTC):

No pod restarts (check every 6 hours)
Memory usage stable (<2GB per pod)
No CrashLoopBackOff
Logs clean (no recurring errors)
Performance normal (response times <500ms)
WebSocket connections stable
User workspace usage <5GB (monitor df -h /workspace)

Commands for Monitoring:

# Check pod status
kubectl get pods -n coditect-app -l app=coditect-combined-hybrid

# Check resource usage
kubectl top pods -n coditect-app -l app=coditect-combined-hybrid

# Check logs for errors
kubectl logs -f coditect-combined-hybrid-0 -n coditect-app --tail=100

# Check PVC usage
kubectl exec coditect-combined-hybrid-0 -n coditect-app -- df -h /workspace

# Check pod events
kubectl get events -n coditect-app --sort-by='.lastTimestamp' | grep hybrid | tail -20

Alert Thresholds:

⚠️ Memory >1.5GB → Investigate
⚠️ Disk usage >8GB (80%) → Expand PVC to 20GB
🚨 Pod restarts >3 in 24h → Consider rollback
🚨 Errors in logs (recurring) → Investigate immediately
