Compose是什么
Compose是一个定义和管理多容器的工具，也是一种容器编排工具，前身是Pig，使用Python语言编写。使用Compose配置文件描述多个容器应用的构架，比如使用什么镜像，数据卷，网络，映射端口等；然后用一条命令管理所有服务，比如启动，停止，重启等
系统为ubuntu18.04 切换root用户使用命令 sudo -i
安装（也可以github下载二进制包安装）
sudo apt-get install python-pip sudo pip install docker-compose
查看版本
docker-compose --version
安装docker
apt install docker.io
查看版本
docker info
docker-compose读取文件夹下面的yml文件
编辑文件docker-compose.yml
version: '3'
services:
web:
build: .
ports:
- "8888:80"
version：定义版本有1,2,3版本
services：定义服务
web：服务名是web
build：在本目录构建
ports：端口映射8888映射容器的80端口
编辑Dockerfile
FROM centos:6 MAINTAINER liuyueming RUN yum install -y httpd php php-gd php-mysql RUN echo "<?php phpinfo()?>" > /var/www/html/index.php CMD ["/usr/sbin/httpd","-D","FOREGROUND"] EXPOSE 80
PS:参数D要加- 否则启动失败
文件目录如下
构建
docker-compose up
构建后会生成名为php_web的镜像（镜像默认命名规则为文件夹_服务名）
完毕查看
docker-compose ps docker ps
web页面访问 http://ip:8888
