Root cause: Superset 4.1.2 ignores SQLALCHEMY_DATABASE_URI env var —
always falls back to SQLite. With separate init+web containers, the
init container's SQLite DB is lost → web container has no admin user
→ JWT login returns 401.
Fix:
- Install psycopg2-binary at container start (python -m pip install)
- Create /tmp/superset_config.py via heredoc that reads SUPERSET_DB_URI
- Set SUPERSET_CONFIG_PATH=/tmp/superset_config.py
- Use Docker bridge IP (not localhost) for Postgres from inside container
Now all 10 integration tests pass, including:
- test_jwt_login_success (access_token + refresh_token)
- test_jwt_authenticated_api_call (Bearer token → /api/v1/dashboard/)
- 4 health checks + 2 form-auth + 2 client construct
