由官方提供：

root@ubuntu18_04:~#

 curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

root@ubuntu18_04:~# chmod +x /usr/local/bin/docker-compose

root@ubuntu18_04:~# docker-compose --version
docker-compose version 1.24.1, build 4667896b

Docker compose使用：

创建docker-compose.yml文件

root@ubuntu18_04:~# vim docker-compose.yml

version: '3'
services:
  web:
    build: .
    ports:
      - "8888:80"

端口：本机的8888映射到容器的80

创建Dockerfile文件
