🚀 Deployment Instructions

Prerequisites

1. Database

   # Ensure PostgreSQL is running
   # Database: external_db
   # User: external_user
   

2. Redis

   # Ensure Redis is running
   # Default: redis://external-redis:6379/0
   

3. API Keys

   • AEMET API Key (Spanish weather)
   • Madrid OpenData API Key (traffic)

Step 1: Apply Database Migration

cd /Users/urtzialfaro/Documents/bakery-ia/services/external

# Run migration
alembic upgrade head

# Verify tables
psql $DATABASE_URL -c "\dt city_*"
# Expected: city_weather_data, city_traffic_data

Step 2: Configure Kubernetes Secrets

cd /Users/urtzialfaro/Documents/bakery-ia/infrastructure/kubernetes/external

# Edit secrets.yaml with actual values
# Replace YOUR_AEMET_API_KEY_HERE
# Replace YOUR_MADRID_OPENDATA_KEY_HERE
# Replace YOUR_DB_PASSWORD_HERE

# Apply secrets
kubectl apply -f secrets.yaml
kubectl apply -f configmap.yaml

Step 3: Run Initialization Job

# Apply init job
kubectl apply -f init-job.yaml

# Monitor progress
kubectl logs -f job/external-data-init -n bakery-ia

# Check completion
kubectl get job external-data-init -n bakery-ia
# Should show: COMPLETIONS 1/1

Expected output:

Starting data initialization job months=24
Initializing city data city=Madrid start=2023-10-07 end=2025-10-07
Madrid weather data fetched records=XXXX
Madrid traffic data fetched records=XXXX
City initialization complete city=Madrid weather_records=XXXX traffic_records=XXXX
✅ Data initialization completed successfully

Step 4: Deploy Main Service

# Apply deployment
kubectl apply -f deployment.yaml

# Wait for readiness
kubectl wait --for=condition=ready pod -l app=external-service -n bakery-ia --timeout=300s

# Verify deployment
kubectl get pods -n bakery-ia -l app=external-service

Step 5: Schedule Monthly CronJob

# Apply cronjob
kubectl apply -f cronjob.yaml

# Verify schedule
kubectl get cronjob external-data-rotation -n bakery-ia

# Expected output:
# NAME                      SCHEDULE      SUSPEND   ACTIVE   LAST SCHEDULE   AGE
# external-data-rotation    0 2 1 * *     False     0        <none>          1m

📊 Monitoring

Check Job Status

# Init job
kubectl logs job/external-data-init -n bakery-ia

# CronJob history
kubectl get jobs -n bakery-ia -l job=data-rotation --sort-by=.metadata.creationTimestamp

Check Service Health

curl http://localhost:8000/health/ready
curl http://localhost:8000/health/live

Check Database Records

psql $DATABASE_URL

# Weather records per city
SELECT city_id, COUNT(*), MIN(date), MAX(date)
FROM city_weather_data
GROUP BY city_id;

# Traffic records per city
SELECT city_id, COUNT(*), MIN(date), MAX(date)
FROM city_traffic_data
GROUP BY city_id;

Check Redis Cache

redis-cli

# Check cache keys
KEYS weather:*
KEYS traffic:*

# Check cache hit stats (if configured)
INFO stats

---

🔧 Configuration

Add New City

1. Edit services/external/app/registry/city_registry.py:

CityDefinition(
    city_id="valencia",
    name="Valencia",
    country=Country.SPAIN,
    latitude=39.4699,
    longitude=-0.3763,
    radius_km=25.0,
    weather_provider=WeatherProvider.AEMET,
    weather_config={"station_ids": ["8416"], "municipality_code": "46250"},
    traffic_provider=TrafficProvider.VALENCIA_OPENDATA,
    traffic_config={"api_endpoint": "https://..."},
    timezone="Europe/Madrid",
    population=800_000,
    enabled=True  # Enable the city
)

2. Create adapter services/external/app/ingestion/adapters/valencia_adapter.py

3. Register in adapters/__init__.py:

ADAPTER_REGISTRY = {
    "madrid": MadridAdapter,
    "valencia": ValenciaAdapter,  # Add
}

4. Re-run init job or manually populate data

Adjust Data Retention

Edit infrastructure/kubernetes/external/configmap.yaml:

data:
  retention-months: "36"  # Change from 24 to 36 months

Re-deploy:

kubectl apply -f configmap.yaml
kubectl rollout restart deployment external-service -n bakery-ia

---

🐛 Troubleshooting

Init Job Fails

# Check logs
kubectl logs job/external-data-init -n bakery-ia

# Common issues:
# - Missing API keys → Check secrets
# - Database connection → Check DATABASE_URL
# - External API timeout → Increase backoffLimit in init-job.yaml

Service Not Ready

# Check readiness probe
kubectl describe pod -l app=external-service -n bakery-ia | grep -A 10 Readiness

# Common issues:
# - No data in database → Run init job
# - Database migration not applied → Run alembic upgrade head

Cache Not Working

# Check Redis connection
kubectl exec -it deployment/external-service -n bakery-ia -- redis-cli -u $REDIS_URL ping
# Expected: PONG

# Check cache keys
kubectl exec -it deployment/external-service -n bakery-ia -- redis-cli -u $REDIS_URL KEYS "*"

Slow Queries

# Enable query logging in PostgreSQL
# Check for missing indexes
psql $DATABASE_URL -c "\d city_weather_data"
# Should have: idx_city_weather_lookup, ix_city_weather_data_city_id, ix_city_weather_data_date

psql $DATABASE_URL -c "\d city_traffic_data"
# Should have: idx_city_traffic_lookup, ix_city_traffic_data_city_id, ix_city_traffic_data_date

📈 Performance Benchmarks

Expected performance (after cache warm-up):

Operation	Before (Old)	After (New)	Improvement
Historical Weather (1 month)	3-5 seconds	<100ms	30-50x faster
Historical Traffic (1 month)	5-10 seconds	<100ms	50-100x faster
Training Data Load (24 months)	60-120 seconds	1-2 seconds	60x faster
Redundant Fetches	N tenants × 1 request each	1 request shared	N x deduplication

🔄 Maintenance

Monthly (Automatic via CronJob)

• Data rotation happens on 1st of each month at 2am UTC
• Deletes data older than 24 months
• Ingests last month's data
• No manual intervention needed

Quarterly

• Review cache hit rates
• Optimize cache TTL if needed
• Review database indexes

Yearly

• Review city registry (add/remove cities)
• Update API keys if expired
• Review retention policy (24 months vs longer)
