# POST3-010: Production Docker Compose setup

**Status:** Todo
**Priority:** P1
**Blocked by:** POST3-009

## Description

Create a production-oriented Docker Compose setup that runs post3-server alongside PostgreSQL, with proper networking, health checks, and configuration.

## Acceptance Criteria

- [ ] `Dockerfile` (multi-stage) for post3-server:
  - Builder stage: rust image, compile release binary
  - Runtime stage: debian-slim or alpine, copy binary + migrations
  - Health check endpoint (add `GET /health` to router)
  - Non-root user
- [ ] `templates/docker-compose.production.yaml`:
  - `postgres` service (PostgreSQL 18, persistent volume, health check)
  - `post3` service (built image, depends_on postgres healthy, DATABASE_URL from env)
  - Named volumes for PostgreSQL data
  - Internal network
  - Port 9000 exposed for post3
- [ ] `templates/.env.example` — sample env file for production
- [ ] `GET /health` endpoint on the server (returns 200 when DB is reachable)
- [ ] `mise.toml` tasks:
  - `prod:up` — start production compose
  - `prod:down` — stop production compose
  - `prod:build` — build the Docker image
- [ ] README section on production deployment

## Notes

The CI pipeline (POST3-009) will produce the container image. This ticket handles the compose orchestration for self-hosted deployment.
