- 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

 | 2 keepeye 2019-01-29 18:06:33 +08:00 看 dockerfile 你没运行服务啊，CMD 呢？ |
| 3 keepeye 2019-01-29 18:08:40 +08:00 ``` FROM ubuntu:14.04 MAINTAINER xxx ADD bin/mtd /root/run CMD ["/root/run"] ``` |
 | 4 kaneg 2019-01-29 19:59:15 +08:00 via iPhone 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 |
 | 5 MilkShake OP @keepeye 我的 Dockerfile，RUN 加了这么一句话 systemctl enable httpd.service |
| 7 MilkShake 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？ |
| 8 keepeye 2019-01-30 10:08:57 +08:00 @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 |
 | 9 BlackHole1 PRO 最后加个 CMD bash |
