一、配置目录结构

1.1 crontabs

# do daily/weekly/monthly maintenance
# min   hour    day     month   weekday command
# *         *         *         *         *         /usr/bin/php /usr/share/nginx/html/artisan schedule:run >> /dev/null 2>&1

Tips：一般在生产环境都是负载均衡，定时任务是单独在一个容器执行，故此是注释掉的，需要单独在定时任务容器中打开即可。

2.1 nginx与php配置文件

Tips：由于php配置文件是监听的sock,默认情况下监听端口 9000。PHP-FPM使用Unix套接字，这避免了TCP的开销。

3.1 php

三、镜像制作与启动

3.1 根据Dockerfile制作镜像

3.2 查看制作的镜像

3.3 启动镜像

3.4 浏览器查看是否成功

四、镜像发布

4.1 镜像发布

一定要登录

4.2 自动构建

当关联的github代码发生改变是，自动触发构建。
