参考[使用文档][Link 1]和[语法文档][Link 2]

## 安装方法（Linux） ##

//下载
    sudo curl -L "https://github.com/docker/compose/releases/download/1.25.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    //授权
    sudo chmod +x /usr/local/bin/docker-compose
    //软链接
    sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
    //测试
    docker-compose --version

## 常用命令 ##

//忽略缓存，重新构建镜像
    docker-compose --no-cache build image1 image2 ...
    //【后台】构建镜像，启动容器
    docker-compose up -d
    //关掉容器，并删除容器
    docker-compose down
    //关掉容器，并删除容器和没有指定tag的镜像（一般指那些从dockerfile创建的镜像，有更新文件时，这个比较好用）
    docker-compose down --rmi local

## 参考样例 ##

    networks:		#定义网络

        name: xxl		#网络名称
