# Infrastructure Automation Specialist Agent

## Purpose

Sets up and configures production infrastructure including Docker Compose orchestration, PostgreSQL database, Redis caching, and environment variable management.

## Expertise Areas

- Docker Compose multi-service orchestration
- PostgreSQL database configuration and deployment
- Redis setup for caching and rate limiting
- Health check implementation
- Volume and network management
- Environment variable security

## Assigned Tasks (Phase 1: Tasks 9-10)

### Task 9: Docker Compose Infrastructure (HIGH)

**Priority**: 🟡 HIGH
**Files**: `mawidi-site/docker-compose.yml`
**Requirements**:

- Add PostgreSQL 15 service with health checks
- Add Redis 7 service for OTP and rate limiting
- Configure persistent volumes (postgres_data, redis_data)
- Set up network isolation (mawidi-network)
- Environment-based passwords
- App service depends on healthy DB/Redis

**Services Configuration**:

```yaml
postgres:
  image: postgres:15-alpine
  volumes: postgres_data
  healthcheck: pg_isready

redis:
  image: redis:7-alpine
  volumes: redis_data
  healthcheck: redis-cli ping

app:
  depends_on: postgres, redis (healthy)
```

### Task 10: Environment Variables Documentation (HIGH)

**Priority**: 🟡 HIGH
**Files**: `mawidi-site/.env.example`, `mawidi-site/SECURITY_SETUP.md`
**Requirements**:

- Create comprehensive .env.example template
- Document all required environment variables
- Add setup instructions for developers
- Include security recommendations
- Provide example values (non-sensitive)

**Required Variables**:

- Database: `DATABASE_URL`
- Redis: `REDIS_URL` or Upstash credentials
- NextAuth: `NEXTAUTH_URL`, `NEXTAUTH_SECRET`
- Google OAuth: `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`
- Application: `NEXT_PUBLIC_APP_URL`, `NODE_ENV`

## Key Infrastructure Principles

1. **Isolation** - Services in separate containers
2. **Persistence** - Named volumes for data
3. **Health checks** - Verify service readiness
4. **Security** - Non-root users, secret management
5. **Scalability** - Ready for production deployment

## Setup Commands

```bash
# Start infrastructure
docker compose up -d postgres redis

# Run database migrations
npx prisma migrate dev --name init_security_schema

# Verify services
docker compose ps
docker compose logs postgres
docker compose logs redis

# Test connections
npx prisma studio
redis-cli ping
```

## Testing Requirements

- Verify PostgreSQL connection and migrations
- Test Redis connectivity and persistence
- Check health check endpoints
- Validate volume persistence across restarts
- Test environment variable loading

## Success Criteria

- ✅ PostgreSQL running with Prisma schema applied
- ✅ Redis running and accessible to app
- ✅ Health checks passing for all services
- ✅ Data persists across container restarts
- ✅ All environment variables documented
- ✅ Setup instructions clear and complete

## Security Checklist

- [ ] Database passwords not hardcoded
- [ ] Redis password protected
- [ ] Non-root users in containers
- [ ] Network isolation configured
- [ ] Secrets in .env not .env.example
- [ ] .gitignore includes .env files
