Phase 1 Plan 1: Docker Compose + Config Foundation Summary

One-liner: Five-service Compose stack (postgres:17-alpine + minio + redis:7-alpine + celery-worker + backend) with health-checked depends_on, two-user PostgreSQL init script, and Pydantic Settings class reading all Phase 1 env vars.

Tasks Completed

Task	Name	Commit	Key Files
1	Replace docker-compose.yml with five-service stack	983ecd8	docker-compose.yml, docker/postgres/initdb.d/01-init-users.sql, .gitignore
2	Extend .env.example with all Phase 1 variables	beb55ca	.env.example
3	Replace backend/config.py with Pydantic Settings + extend requirements.txt	6c507d5	backend/config.py, backend/requirements.txt

What Was Built

docker-compose.yml

Rewrote from a 2-service file (backend + frontend) to a full 6-service Phase 1 stack:

• postgres (postgres:17-alpine): health-checked with pg_isready -U postgres -d docuvault; mounts docker/postgres/initdb.d as /docker-entrypoint-initdb.d:ro
• minio (minio/minio:latest): health-checked with mc ready local (curl removed from image); exposes ports 9000 and 9001
• redis (redis:7-alpine): runs redis-server --requirepass ${REDIS_PASSWORD}; health-checked with redis-cli -a ${REDIS_PASSWORD} ping to avoid NOAUTH errors
• backend: depends on all three infra services with condition: service_healthy; removed ./backend/data:/app/data volume per D-04
• celery-worker: same build as backend; command celery -A celery_app worker --loglevel=info -Q documents per D-10; has DATABASE_URL but NOT DATABASE_MIGRATE_URL (workers need no DDL)
• frontend: unchanged from original
• Top-level volumes: block with postgres_data: and minio_data: named volumes

docker/postgres/initdb.d/01-init-users.sql

Provisions both PostgreSQL users on first container start:

• docuvault_migrate with GRANT ALL PRIVILEGES ON DATABASE docuvault (DDL — Alembic only)
• docuvault_app with GRANT CONNECT ON DATABASE docuvault (DML — FastAPI + Celery)
• Comment notes that table-level grants are issued in the Alembic migration (Plan 03)

.env.example

Extended from 6 lines to a fully documented 4-section env file with 14 named variables grouped by service. All passwords use changeme_* placeholders consistent between the env file and the SQL init script.

backend/config.py

Added Settings(BaseSettings) class with SettingsConfigDict (pydantic-settings v2 API). Instantiates settings = Settings() at module level. Preserved all legacy flat-file constants verbatim (DATA_DIR, UPLOADS_DIR, METADATA_DIR, TOPICS_FILE, SETTINGS_FILE, DEFAULT_SYSTEM_PROMPT, DEFAULT_SETTINGS, ensure_data_dirs()).

backend/requirements.txt

Removed filelock>=3.14. Added 7 new dependencies: sqlalchemy[asyncio]>=2.0.49, psycopg[binary]>=3.3.4, alembic>=1.18.4, minio>=7.2.20, celery[redis]>=5.6.3, redis>=7.4.0, aiosqlite>=0.20.0. Bumped pytest-asyncio to >=1.3.0.

Verification Results

• docker compose --env-file .env.example config -q exits 0 (no parse errors)
• from config import settings; settings.minio_bucket returns "docuvault"
• settings.database_url starts with postgresql+psycopg://
• grep -c "filelock" backend/requirements.txt returns 0
• All 14 env vars present in .env.example
• All 6 service keys present in docker-compose.yml
• SQL init script creates both docuvault_app and docuvault_migrate users

Deviations from Plan

None — plan executed exactly as written.

The legacy flat-file constants were preserved verbatim as specified in the plan's <interfaces> section. The SettingsConfigDict approach (pydantic-settings v2 API) was used as specified. The celery-worker service omits DATABASE_MIGRATE_URL as specified (workers need no DDL access).

Known Stubs

None — this plan is infrastructure and configuration only. No UI data flows or component wiring involved.

Threat Flags

None — all threat mitigations from the plan's threat model are implemented:

• T-01-01-01 (PostgreSQL EoP): Two-DSN pattern implemented (app user DML-only, migrate user DDL-only)
• T-01-01-02 (MinIO root creds): MINIO_ROOT_USER/PASSWORD separate from MINIO_ACCESS_KEY/SECRET_KEY in both compose and env.example
• T-01-01-03 (Redis unauthenticated): --requirepass ${REDIS_PASSWORD} + authenticated healthcheck
• T-01-01-04 (Secret leakage): .env added to .gitignore; only .env.example with changeme_* values committed
• T-01-01-05 (Race condition startup): depends_on: condition: service_healthy on all infra dependencies

Self-Check: PASSED

• docker-compose.yml exists and contains 6 services
• docker/postgres/initdb.d/01-init-users.sql exists
• .gitignore contains .env
• .env.example has 14 variables
• backend/config.py has Settings class and settings instance
• backend/requirements.txt has no filelock, has all 7 new packages
• Commits 983ecd8, beb55ca, 6c507d5 confirmed in git log
