4. Image Pull Success ✅

Pod Status:

Pods successfully pull image from Artifact Registry ✅
No more ImagePullBackOff errors ✅
Pods reach ContainerCreating → Running state ✅

❌ Current Blocker: Application Crashes (CrashLoopBackOff)

Issue Description

Pods successfully start but application crashes immediately with CrashLoopBackOff status.

Pod Status:

NAME                                READY   STATUS             RESTARTS      AGE
coditect-backend-6f9f8f799f-bsr84   0/1     CrashLoopBackOff   3 (27s ago)   7m14s

Root Cause Analysis

The Django/Gunicorn application requires external dependencies that haven't been deployed yet:

PostgreSQL Database - Application connects to DB_HOST but database doesn't exist
Redis Cache - Application connects to REDIS_HOST but Redis isn't running
Database Migrations - Even if DB exists, tables need to be created via python manage.py migrate

Application Startup Flow:

Container starts
    ↓
Django loads settings (license_platform.settings.production)
    ↓
Django connects to database (DB_HOST=10.0.0.5) ❌ Connection refused
    ↓
Application crashes with database connection error
    ↓
Kubernetes restarts pod (CrashLoopBackOff)

🔧 Required Next Steps

Immediate (Required for Application to Start)

1. Deploy PostgreSQL Database (15-30 minutes)

Option A: Cloud SQL (Recommended for Production)

# Create Cloud SQL instance
gcloud sql instances create coditect-staging-db \
  --database-version=POSTGRES_15 \
  --tier=db-g1-small \
  --region=us-central1 \
  --network=projects/coditect-cloud-infra/global/networks/default \
  --no-assign-ip

# Get private IP
gcloud sql instances describe coditect-staging-db \
  --format="value(ipAddresses[0].ipAddress)"

# Create database
gcloud sql databases create coditect_licenses_staging \
  --instance=coditect-staging-db

# Create user
gcloud sql users create license_api_staging \
  --instance=coditect-staging-db \
  --password="<USE_SECRET_FROM_backend-secrets>"

# Update backend-secrets with real DB IP
kubectl create secret generic backend-secrets \
  --namespace=coditect-staging \
  --from-literal=db-host="<REAL_CLOUD_SQL_IP>" \
  --dry-run=client -o yaml | kubectl apply -f -

Option B: Kubernetes StatefulSet (Development/Staging)

# Apply PostgreSQL StatefulSet
kubectl apply -f deployment/kubernetes/staging/postgres-statefulset.yaml

# Wait for PostgreSQL to be ready
kubectl wait --for=condition=ready pod -l app=postgresql -n coditect-staging --timeout=300s

# Get PostgreSQL service IP
kubectl get service postgresql-internal -n coditect-staging \
  -o jsonpath='{.spec.clusterIP}'

# Update backend-secrets with PostgreSQL service IP
kubectl create secret generic backend-secrets \
  --namespace=coditect-staging \
  --from-literal=db-host="<POSTGRESQL_SERVICE_IP>" \
  --dry-run=client -o yaml | kubectl apply -f -

2. Deploy Redis Cache (10-15 minutes)

Option A: Cloud Memorystore (Recommended for Production)

# Create Redis instance
gcloud redis instances create coditect-staging-redis \
  --size=1 \
  --region=us-central1 \
  --network=default \
  --redis-version=redis_7_0

# Get Redis IP
gcloud redis instances describe coditect-staging-redis \
  --region=us-central1 \
  --format="value(host)"

# Update backend-secrets with Redis IP
kubectl create secret generic backend-secrets \
  --namespace=coditect-staging \
  --from-literal=redis-host="<REDIS_IP>" \
  --dry-run=client -o yaml | kubectl apply -f -

Option B: Kubernetes StatefulSet (Development/Staging)

# Apply Redis StatefulSet
kubectl apply -f deployment/kubernetes/staging/redis-statefulset.yaml

# Wait for Redis to be ready
kubectl wait --for=condition=ready pod -l app=redis -n coditect-staging --timeout=300s

# Get Redis service IP
kubectl get service redis-internal -n coditect-staging \
  -o jsonpath='{.spec.clusterIP}'

# Update backend-secrets with Redis service IP
kubectl create secret generic backend-secrets \
  --namespace=coditect-staging \
  --from-literal=redis-host="<REDIS_SERVICE_IP>" \
  --dry-run=client -o yaml | kubectl apply -f -

3. Run Database Migrations (5-10 minutes)

After PostgreSQL is running:

# Create migration job
kubectl apply -f - <<EOF
apiVersion: batch/v1
kind: Job
metadata:
  name: django-migrate
  namespace: coditect-staging
spec:
  template:
    spec:
      serviceAccountName: coditect-cloud-backend
      containers:
      - name: migrate
        image: us-central1-docker.pkg.dev/coditect-cloud-infra/coditect-backend/coditect-cloud-backend:v1.0.0-staging
        command: ["python", "manage.py", "migrate"]
        envFrom:
        - secretRef:
            name: backend-secrets
      restartPolicy: Never
  backoffLimit: 3
EOF

# Watch migration job
kubectl logs -f job/django-migrate -n coditect-staging

# Expected output:
# Operations to perform:
#   Apply all migrations: admin, auth, contenttypes, sessions, licenses
# Running migrations:
#   Applying contenttypes.0001_initial... OK
#   Applying auth.0001_initial... OK
#   ...

4. Restart Deployment (1-2 minutes)

After database and Redis are ready:

# Restart deployment to pick up new secrets
kubectl rollout restart deployment/coditect-backend -n coditect-staging

# Watch rollout
kubectl rollout status deployment/coditect-backend -n coditect-staging

# Verify pods are running
kubectl get pods -n coditect-staging -l app=coditect-backend

# Expected output:
# NAME                                READY   STATUS    RESTARTS   AGE
# coditect-backend-xxxxx-xxxxx        1/1     Running   0          30s
# coditect-backend-xxxxx-xxxxx        1/1     Running   0          30s

Infrastructure Dependencies

PostgreSQL: ❌ Not deployed
Redis: ❌ Not deployed
Cloud SQL: ❌ Not created
Memorystore: ❌ Not created

⏭️ Recommended Deployment Path

Path A: Quick Staging Deployment (30-45 minutes)

Use Kubernetes StatefulSets for database and Redis (easier, faster for staging):

Deploy PostgreSQL StatefulSet (15 min)
Deploy Redis StatefulSet (10 min)
Update backend-secrets with service IPs (2 min)
Run database migrations (5 min)
Restart deployment (2 min)
Verify pods running (1 min)
Get LoadBalancer IP and run smoke tests (5 min)

Total: ~40 minutes to working staging environment

Path B: Production-Ready Deployment (1-2 hours)

Use Cloud SQL and Memorystore (better for production):

Create Cloud SQL instance (20-30 min for provisioning)
Create Memorystore Redis (15-20 min for provisioning)
Configure private networking (10 min)
Update backend-secrets with real IPs (2 min)
Run database migrations (5 min)
Restart deployment (2 min)
Verify pods running (1 min)
Get LoadBalancer IP and run smoke tests (5 min)

Total: ~1-2 hours to production-grade staging environment

🎯 Success Criteria

Application Running Successfully

# Pods should be Running
kubectl get pods -n coditect-staging -l app=coditect-backend
# NAME                                READY   STATUS    RESTARTS   AGE
# coditect-backend-xxxxx-xxxxx        1/1     Running   0          5m
# coditect-backend-xxxxx-xxxxx        1/1     Running   0          5m

Health Checks Passing

# Get LoadBalancer IP
export STAGING_IP=$(kubectl get service coditect-backend -n coditect-staging \
  -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

# Test liveness endpoint
curl http://${STAGING_IP}/api/v1/health/live
# Expected: {"status": "healthy", "timestamp": "2025-12-01T05:30:00Z"}

# Test readiness endpoint
curl http://${STAGING_IP}/api/v1/health/ready
# Expected: {"status": "ready", "database": "connected", "redis": "connected"}

Database Connectivity

# Check database connection from pod
kubectl exec -it -n coditect-staging deployment/coditect-backend -- \
  python manage.py dbshell -c "SELECT 1;"
# Expected: 1

Redis Connectivity

# Check Redis connection from pod
kubectl exec -it -n coditect-staging deployment/coditect-backend -- \
  python manage.py shell -c "from django.core.cache import cache; print(cache.set('test', 'ok')); print(cache.get('test'))"
# Expected: True
#          ok

📋 Lessons Learned

1. Google Container Registry (GCR) Shutdown

Critical Discovery: GCR was shut down on March 18, 2025. All deployments MUST use Artifact Registry.

Migration Required:

Enable Artifact Registry API
Create Artifact Registry repository
Configure Docker authentication for Artifact Registry
Update all image paths from gcr.io/ to [region]-docker.pkg.dev/
Grant roles/artifactregistry.reader to GKE compute service account

2. Multi-Platform Docker Builds

Issue: Local Docker builds on macOS (arm64) don't work on GKE (linux/amd64).

Solution:

docker buildx build --platform linux/amd64 -t IMAGE --push .

3. Infrastructure Dependencies

Issue: Application can't start without database and Redis.

Recommendation: Deploy infrastructure BEFORE deploying application, or use init containers to wait for dependencies.

4. Kubernetes Secrets with Placeholder IPs

Issue: Created secrets with placeholder IPs (10.0.0.5, 10.0.0.3) that don't exist.

Recommendation: Deploy infrastructure first, get real IPs, then create secrets.
