  • Retry build: Build ID 94308548-5972-4e61-846f-f13c043858b4 ✅ SUCCESS
  • Verify image pushed to Artifact Registry: us-central1-docker.pkg.dev/serene-voltage-464305-n2/coditect/coditect-v5-api:latest

Completed: 2025-10-07 17:27 Build Time: 2m59s Issues:

  • ❌ First build failed: Authentication token expired during build
  • ✅ Second build succeeded

Phase 3: Backend API Deployment to GKE​

3.1 Kubernetes Manifests ✅​

  • Create k8s-deployment.yaml with Deployment and Service
  • Configure 3 replicas for high availability
  • Set resource limits: 512Mi-1Gi memory, 500m-1000m CPU
  • Configure health checks: liveness probe (30s initial), readiness probe (10s initial)
  • Mount JWT secret from Kubernetes: jwt-secret-k8s
  • Set FDB_CLUSTER_FILE environment variable

Completed: 2025-10-07 17:30 Issues: None

3.2 Deploy to GKE ⚠️​

  • Apply Kubernetes manifests: kubectl apply -f k8s-deployment.yaml
  • Verify deployment created: coditect-api-v5 deployment created
  • Verify service created: coditect-api-v5-service (ClusterIP)
  • Check pod status: 🔴 ISSUE - Pods in CrashLoopBackOff

Status: 🔴 BLOCKED Started: 2025-10-07 17:30 Issues:

  • ❌ Pods crash immediately after startup
  • ❌ No logs visible (container exits before logging)
  • ❌ CrashLoopBackOff restart loop

Current Pod Status:​

NAME                               READY   STATUS             RESTARTS
coditect-api-v5-5744b8d5f7-f2fdr   0/1     CrashLoopBackOff   2
coditect-api-v5-5744b8d5f7-pfl7j   0/1     CrashLoopBackOff   2
coditect-api-v5-5744b8d5f7-z6bjx   0/1     CrashLoopBackOff   2

3.3 Troubleshooting Pod Crashes 🔴 IN PROGRESS​

Hypothesis: Application fails to connect to FoundationDB and exits

Debugging Steps to Try:​

  • Get detailed pod logs: kubectl logs -n coditect-app <POD_NAME> --previous
  • Describe pod for events: kubectl describe pod -n coditect-app <POD_NAME>
  • Test FDB connection from debug pod: 
    kubectl run -it --rm fdb-debug --image=foundationdb/foundationdb:7.1.27 \
      --restart=Never -n coditect-app -- bash

    # Inside pod:
    cat > /tmp/fdb.cluster << 'EOF'
    coditect:production@foundationdb-0.fdb-cluster.coditect-app.svc.cluster.local:4500
    EOF

    fdbcli -C /tmp/fdb.cluster
  • Check if FDB cluster is actually accessible via DNS: 
    kubectl run -it --rm dns-test --image=busybox \
      --restart=Never -n coditect-app -- \
      nslookup foundationdb-0.fdb-cluster.coditect-app.svc.cluster.local
  • Verify FDB service endpoints are correct: kubectl get endpoints fdb-cluster -n coditect-app
  • Check if issue is with FDB cluster file content vs actual cluster state
  • Consider making FDB connection optional in main.rs (start server even if FDB fails)

Potential Fixes:​

  1. Option A: Make FDB connection optional (recommended for initial testing)

    • Modify backend/src/main.rs to continue even if FDB connection fails
    • Start HTTP server regardless of FDB status
    • Add /health endpoint that works without FDB

  2. Option B: Fix FDB connection (production solution)

    • Verify FDB cluster file matches actual cluster configuration
    • Check if DNS resolution works inside pods
    • Ensure FDB service is accessible from coditect-app namespace

  3. Option C: Use FDB proxy instead

    • Change fdb.cluster to use proxy LoadBalancer IP: 10.128.0.10:4500
    • Rebuild and redeploy

Next Action: Try debugging steps to identify root cause

Phase 4: Ingress Configuration​

4.1 Update Ingress for V5 API ⬜​

  • Backup current ingress: kubectl get ingress coditect-production-ingress -n coditect-app -o yaml > /tmp/ingress-backup.yaml
  • Edit ingress to add V5 path: kubectl edit ingress coditect-production-ingress -n coditect-app
  • Add path /api/v5 BEFORE /api (order matters!): 
    - path: /api/v5
      pathType: Prefix
      backend:
        service:
          name: coditect-api-v5-service
          port:
            number: 80
  • Verify ingress updated: kubectl describe ingress coditect-production-ingress -n coditect-app

🔧 Active Issues & Blockers​

Issue #1: Backend API Pods CrashLoopBackOff 🔴 CRITICAL​

Status: 🔴 Active Priority: P0 (Blocker) Discovered: 2025-10-07 17:30 Impact: Blocks all downstream deployment steps

Symptoms:

  • Pods crash immediately after startup
  • CrashLoopBackOff restart loop
  • No logs visible (container exits before logging)

Hypothesis:

  • Application fails to connect to FoundationDB
  • FDB connection error causes app to panic/exit
  • Main.rs exits with error if FDB connection fails after max retries

Next Steps:

  1. Get detailed pod logs with --previous flag
  2. Test FDB connectivity from debug pod
  3. Consider making FDB connection optional for initial testing

Assigned To: Needs investigation ETA: TBD

📝 Lessons Learned​

Build Phase Lessons ✅​

  1. FoundationDB client must be installed in builder stage

    • The foundationdb-gen crate needs /usr/include/foundationdb/fdb.options at compile time
    • Installing FDB client only in runtime stage causes build failure
    • Solution: Install in builder stage before running cargo build

  2. Clang is required for Rust FDB bindings

    • The foundationdb-sys crate uses bindgen which requires clang
    • Missing clang causes cryptic build errors
    • Solution: Install clang and libclang-dev in builder stage

  3. Cloud Build machine type matters for Rust

    • Default machine type was too slow for Rust compilation
    • Upgraded to N1_HIGHCPU_8 reduced build time significantly
    • Build time: ~3 minutes with N1_HIGHCPU_8

  4. Authentication tokens can expire during long builds

    • First build failed because auth token expired mid-build
    • Solution: Ensure fresh authentication before starting builds

Deployment Phase Lessons ⚠️​

  1. TBD - Will update as we resolve pod crash issue
