使用 Dockerfile 构建了一个镜像，独独最后的 CMD 不运行，如何破

使用了 supervisord 守护，也创建了目录 mkdir /var/log/supervisor，结果还是不运行。最后的一行命令如下：

CMD ["/usr/bin/supervisord", "-c", "/etc/supervisord.conf"]

从镜像创建容器，然后 docker attach 进去，执行 /usr/bin/supervisord -c /etc/supervisord.conf 是可以正常跑起来里面的服务的。

求教 v2er 们该如何破。

使用 docker logs 查看。CMD ["/usr/bin/supervisord", "-c", "/etc/supervisord.conf"] 没有日志。但容器启动不起来，attach 过去提示：You cannot attach to a stopped container, start it first。

如果单纯使用 CMD ["/usr/bin/supervisord"] 会得到下面的结果：
/usr/lib/python2.7/site-packages/supervisor/options.py:461: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security.
