# 安装 Docker Compose

## 方式一：作为容器运行（推荐）

Docker Compose 可以作为容器运行，通过一个轻量级 bash 脚本调用。

```bash
# 下载并安装
sudo curl -L --fail \
  https://github.com/docker/compose/releases/download/v2.24.0/docker-compose-$(uname -s)-$(uname -m) \
  -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

# 验证安装
docker-compose --version
```

## 方式二：pip 安装

```bash
pip install docker-compose
```

## 方式三：standalone 二进制

```bash
# 下载指定版本
COMPOSE_VERSION=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep tag_name | cut -d'"' -f4)

curl -L \
  "https://github.com/docker/compose/releases/download/${COMPOSE_VERSION}/docker-compose-$(uname -s)-$(uname -m)" \
  -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose
```

## 快速使用

```yaml
# docker-compose.yml 示例
version: '3.8'
services:
  web:
    image: nginx:latest
    ports:
      - "80:80"
  db:
    image: postgres:13
    environment:
      POSTGRES_PASSWORD: secret
```

```bash
# 启动服务
docker-compose up -d

# 查看状态
docker-compose ps

# 查看日志
docker-compose logs -f

# 停止服务
docker-compose down
```
