requires:

- phase: 14-postgresql-migration/01
|
|
provides: PostgreSQL schema and drizzle-pg migrations directory
|
|
provides:
|
|
- Docker Compose dev file with PostgreSQL 16 for local development
|
|
- Production Docker Compose with Postgres + app dependency chain
|
|
- Lean Dockerfile without native SQLite build dependencies

key-decisions:

- "Dev compose uses hardcoded credentials (gearbox/gearbox) for simplicity"

- "Production compose externalizes POSTGRES_PASSWORD via env var"

- "DATABASE_URL env var pattern for Postgres connection string"

# Phase 14 Plan 02: Docker & Compose for PostgreSQL Summary
|
|
|
|
**PostgreSQL 16 Docker Compose for dev and production, lean Dockerfile without native SQLite build dependencies**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 1 min
|
|
- **Started:** 2026-04-04T10:23:10Z
|
|
- **Completed:** 2026-04-04T10:24:14Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- Created docker-compose.dev.yml providing PostgreSQL 16 on localhost:5432 for local development
|
|
- Rewrote docker-compose.yml with Postgres service, healthcheck, and app dependency chain for production
|
|
- Stripped native build tools (python3/make/g++) from Dockerfile and switched to drizzle-pg migrations
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create Docker Compose files for dev and production** - `50b451b` (feat)
|
|
2. **Task 2: Update Dockerfile and entrypoint for PostgreSQL** - `186e74b` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `docker-compose.dev.yml` - Development Postgres service with hardcoded dev credentials
|
|
- `docker-compose.yml` - Production Postgres + app services with externalized secrets
|
|
- `Dockerfile` - Removed native build deps, copies drizzle-pg instead of drizzle
|
|
|
|
## Decisions Made
|
|
- Dev compose uses hardcoded credentials (gearbox/gearbox) for zero-friction local development
|
|
- Production compose externalizes POSTGRES_PASSWORD via environment variable substitution
|
|
- No changes needed to entrypoint.sh since it already runs the generic migrate.ts script
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Docker infrastructure ready for PostgreSQL-based development and production
|
|
- Developers can run `docker compose -f docker-compose.dev.yml up` to start local Postgres
|
|
- Dockerfile ready to build once drizzle-pg migrations directory exists from Plan 01
