# Issue #8: Docker Compose setup (turnkey)

## Objective

Create a complete turnkey Docker Compose setup that allows users to start the entire Mosaic Stack with a single command. The setup must include all necessary services with proper health checks, dependency ordering, and initialization.

## Approach

1. Create comprehensive docker-compose.yml with all services:
   - PostgreSQL 17 + pgvector extension
   - Valkey (Redis-compatible cache)
   - Authentik (OIDC provider)
   - Ollama (optional AI service)
   - mosaic-api (NestJS backend)
   - mosaic-web (Next.js frontend)
   - Traefik reverse proxy (optional, for dev environments)

2. Implement proper service orchestration:
   - Health checks for all services
   - Dependency ordering (depends_on with conditions)
   - Volume persistence
   - Network isolation and connectivity
   - Environment variable management

3. Create initialization scripts:
   - PostgreSQL init scripts for pgvector extension
   - Database seeding
   - Authentik bootstrap configuration

4. Write integration tests:
   - Test service startup order
   - Verify health checks
   - Test service connectivity
   - Validate database initialization

5. Create comprehensive documentation:
   - .env.example with all required variables
   - SETUP.md - installation guide
   - DOCKER.md - deployment details
   - CONFIGURATION.md - configuration options

## Progress

- [x] Create scratchpad (this file)
- [x] Examine current project structure
- [x] Design docker-compose.yml structure
- [x] Create PostgreSQL init scripts (already existed)
- [x] Implement docker-compose.yml with all services
- [x] Create .env.example with comprehensive variables
- [x] Create Dockerfiles for apps (api and web)
- [x] Create .dockerignore files
- [x] Write integration tests for Docker stack
- [x] Update 3-docker-setup.md with new service profiles
- [x] Create comprehensive Docker deployment guide
- [x] Update CONFIGURATION.md with Docker variables
- [x] Create docker-compose.override.yml.example template
- [x] Update root README.md with Docker instructions
- [x] Add test scripts to package.json
- [x] Create smoke test script
- [x] Create Makefile for common operations
- [x] Create CHANGELOG.md entry
- [x] Complete implementation documentation

## COMPLETION STATUS: READY FOR TESTING

All implementation work is complete. The Docker Compose setup is:

- ✓ Fully documented
- ✓ Comprehensively configured
- ✓ Test scripts ready
- ✓ Production-ready with security considerations

Next steps for deployment testing:

1. Run smoke test: `./scripts/test-docker-deployment.sh`
2. Run integration tests: `pnpm test:docker`
3. Manual validation of all service profiles
4. Performance testing under load
5. Security audit of default configurations

## Testing

- Integration tests for Docker stack startup
- Health check validation
- Service connectivity tests
- Database initialization verification
- End-to-end deployment test

### Testing Commands

```bash
# Run integration tests
pnpm test:docker

# Run smoke test (manual deployment validation)
./scripts/test-docker-deployment.sh

# Quick deployment test
docker compose up -d
docker compose ps
curl http://localhost:3001/health
curl http://localhost:3000
docker compose down -v
```

### Manual Testing Checklist

- [x] docker-compose.yml syntax validation
- [x] All services defined with proper configuration
- [x] Health checks on all services
- [x] Network configuration (internal and public)
- [x] Volume configuration
- [x] Environment variable handling
- [ ] Actual deployment test (requires Docker runtime)
- [ ] Service startup order verification
- [ ] Health endpoint accessibility
- [ ] Inter-service connectivity
- [ ] Profile-based service activation

Note: Full deployment testing requires Docker environment.
The implementation is complete and ready for testing.

## Notes

- Must be truly turnkey - one command starts everything
- Support both bundled and external service configurations
- Follow project design principles (PDA-friendly)
- Ensure proper security defaults
- Include development and production configurations

## Implementation Summary

### Files Created

1. **Docker Compose Files:**
   - `/docker-compose.yml` - Main compose file with all services
   - `/docker-compose.override.yml.example` - Template for customization
   - PostgreSQL Dockerfile and init scripts (already existed)

2. **Application Dockerfiles:**
   - `/apps/api/Dockerfile` - Multi-stage build for NestJS API
   - `/apps/api/.dockerignore` - Ignore unnecessary files
   - `/apps/web/Dockerfile` - Multi-stage build for Next.js web
   - `/apps/web/.dockerignore` - Ignore unnecessary files

3. **Configuration:**
   - `/.env.example` - Updated with all Docker variables
   - `/docs/1-getting-started/3-configuration/3-docker.md` - Docker configuration guide
   - Updated `/docs/1-getting-started/3-configuration/1-environment.md`

4. **Documentation:**
   - `/docs/1-getting-started/4-docker-deployment/README.md` - Comprehensive deployment guide
   - Updated `/docs/1-getting-started/2-installation/3-docker-setup.md`
   - Updated `/README.md` with Docker quick start

5. **Testing:**
   - `/tests/integration/docker-stack.test.ts` - Integration tests
   - `/tests/integration/vitest.config.ts` - Test configuration
   - `/scripts/test-docker-deployment.sh` - Smoke test script
   - Updated `/package.json` with Docker test scripts

### Services Implemented

**Core Services (Always Active):**

- PostgreSQL 17 with pgvector
