Compose 安装

Compose 安装
Linux
Linux 上我们可以从 Github 上下载它的二进制包来使用，最新发行的版本地址：https://github.com/docker/compose/releases。

运行以下命令以下载 Docker Compose 的当前稳定版本：

$ sudo curl -L “https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)” -o /usr/local/bin/docker-compose
要安装其他版本的 Compose，请替换 1.24.1。

将可执行权限应用于二进制文件：

$ sudo chmod +x /usr/local/bin/docker-compose
创建软链：

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试是否安装成功：

$ docker-compose –version
cker-compose version 1.24.1, build 4667896b
