- 今天刚学习 docker-compose，我使用 docker-compose+Dockerfile。只创建了容器了，没有运行容器，直接退出了，不知道是什么原因。
- 下面是配置文件和启动命令
[root@localhost compose]# cat docker-compose.yml
version: '3'
services:
web:
build: .
ports:
- "8888:80"
[root@localhost compose]# cat Dockerfile
FROM centos:7

RUN echo "<?php phpinfo()?>" > /var/www/html/index.php

docker 默认运行结束后就退出了，你需要一个不会结束的程序，比如 sleep infinity 或者 cat

aaa5838769 OP @keepeye 我的 Dockerfile，RUN 加了这么一句话 systemctl enable httpd.service

aaa5838769 OP @vissssa 好的，我一会试试，刚学习，很多知识点不知道

aaa5838769 OP @vissssa docker-compose.yml command 可以执行这句话不 systemctl start httpd，需要加别的参数来配合不？

@aaa5838769 httpd 不要后台运行，docker 要求前台运行的程序，像 top，tail -f 等，否则 docker 命令跑完了直接就 exit 了
