## CONFIGURATION SUMMARY

### PostgreSQL Service
- Image: postgres:16-alpine
- Port: 5432
- Databases:
  * workclub (user: app/devpass) — Application data
  * keycloak (user: keycloak/keycloakpass) — Keycloak metadata
- Healthcheck: pg_isready -U postgres
- Volume: postgres-data:/var/lib/postgresql/data
- Init Script: /docker-entrypoint-initdb.d/init.sql

### Keycloak Service
- Image: quay.io/keycloak/keycloak:26.1
- Port: 8080
- Mode: start-dev --import-realm
- Admin: admin/admin
- Database: keycloak (PostgreSQL)
- Realm Import: ./infra/keycloak → /opt/keycloak/data/import
- Healthcheck: curl -sf http://localhost:8080/health/ready
- Depends on: postgres (service_healthy)

### Networking
- Bridge Network: app-network
- Service Discovery: postgres:5432, localhost:8080 (Keycloak UI)
- JDBC URL: jdbc:postgresql://postgres:5432/keycloak

## TECHNICAL NOTES

1. Alpine images reduce footprint (postgres:16-alpine vs full postgres:16)
2. Separate databases for application and Keycloak prevents conflicts
3. Health checks with appropriate startup periods (30s for Keycloak, 10s for PostgreSQL)
4. Ordered startup: Keycloak waits for healthy PostgreSQL
5. Development credentials hardcoded (will be externalised in production setup)
6. Realm import mechanism allows automated realm configuration (Task 3)

## ENVIRONMENT CONSTRAINTS

- Docker Compose CLI plugin not available in this environment
- Configuration validated via YAML structure verification
- Full integration testing deferred to actual Docker deployment
- All services ready for deployment via: docker compose up -d

## DEPENDENT TASKS

- Task 3: Populate realm-export.json with actual Keycloak realm configuration
- Task 7: PostgreSQL migrations for Entity Framework Core (uses workclub database)
- Task 22: Add backend/frontend services to docker-compose.yml

## VERIFICATION STATUS

✓ YAML Syntax: Valid (structure verified)
✓ Service Configuration: Both postgres and keycloak properly configured
✓ Environment Variables: All required vars present
✓ Volumes: postgres-data volume declared, keycloak realm import mount configured
✓ Networks: app-network bridge network declared
✓ Healthchecks: Configured for both services with appropriate timeouts
✓ Database Setup: init.sql creates workclub and keycloak databases with proper users
✓ Git Commit: Created successfully
✓ Learnings Documented: Task 2 patterns appended to notepad
