Major fixes to database connectivity in Docker:
1. Fix alembic.ini - Changed localhost to postgres (line 90)
- This was the root cause of localhost connection errors
2. Fix database.py default - Changed localhost to postgres
- Ensures correct default when env var not set
3. Fix config.py default - Changed localhost to postgres
- Consistent configuration across all files
4. Fix .env file - Changed DATABASE_URL from localhost to postgres
- Prevents local dev config from overriding Docker config
5. Update Dockerfile.backend - Add debug logging to verify env vars
6. Fix docker-compose.yml frontend port - Changed 3000 to 8888
7. Fix Celery commands - Use 'uv run celery' instead of just 'celery'
8. Remove obsolete 'version' attribute from docker-compose.yml
Verification:
- DATABASE_URL env var: postgresql+asyncpg://postgres:postgres@postgres:5432/mockupaws ✅
- Backend now connects to postgres:5432 instead of localhost ✅
- Frontend accessible at http://localhost:8888✅
Note: There's a separate migration error with index creation
(idx_logs_recent using NOW() - requires IMMUTABLE function).
This is a database migration issue, not a connection issue.
