## Docker Compose 最佳实践

### 1. 网络架构配置

```yaml
# infrastructure/networks.yml
# 全局网络定义（可被所有服务引用）

networks:
  # 公网网络（Caddy + 对外服务）
  public:
    name: automa_public
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.0/16
    labels:
      com.automa.network: "public"
      com.automa.description: "Public-facing services"

  # 监控网络（仅内部）
  monitoring:
    name: automa_monitoring
    driver: bridge
    internal: true  # 不允许访问外网
    ipam:
      config:
        - subnet: 172.21.0.0/16
    labels:
      com.automa.network: "monitoring"

  # Nextcloud 网络
  nextcloud:
    name: automa_nextcloud
    driver: bridge
    ipam:
      config:
        - subnet: 172.22.0.0/16
    labels:
      com.automa.network: "nextcloud"

  # TeamSpeak 网络
  teamspeak:
    name: automa_teamspeak
    driver: bridge
    ipam:
      config:
        - subnet: 172.23.0.0/16
    labels:
      com.automa.network: "teamspeak"
```

**使用方法：**
```bash
# 创建网络
docker network create -d bridge --subnet 172.20.0.0/16 automa_public
docker network create -d bridge --subnet 172.21.0.0/16 --internal automa_monitoring
docker network create -d bridge --subnet 172.22.0.0/16 automa_nextcloud
docker network create -d bridge --subnet 172.23.0.0/16 automa_teamspeak

# 或在 Makefile 中
make network-create
```

### 2. Caddy 反向代理配置

#### `infrastructure/caddy/docker-compose.yml`

```yaml
services:
  caddy:
    image: caddy:2.7-alpine
    container_name: automa-caddy
    restart: unless-stopped

    networks:
      - automa_public
      - automa_nextcloud
      - automa_monitoring

    ports:

      - "443:443"
      - "443:443/udp"  # HTTP/3 (QUIC)

    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile:ro
      - ./data:/data
      - ./config:/config
      - /var/log/caddy:/var/log/caddy

    environment:
      - ACME_AGREE=true

    labels:
      - "com.automa.service=caddy"
      - "com.automa.category=infrastructure"
      - "com.centurylinklabs.watchtower.enable=true"

    healthcheck:
      test: ["CMD", "caddy", "validate", "--config", "/etc/caddy/Caddyfile"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s

    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"
        labels: "com.automa.service"

networks:
