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
