如果默认CMD是shell脚本，则Docker停止退出代码

Question

我正在用supervisord在Docker中构建一个tomcat容器。如果Dockerfile默认命令是

CMD supervisord -c /etc/supervisord.conf 

，当我派遣码头工人停止命令，容器和退出代码成功退出0

但是相反，如果我有

CMD ["/run"] 

和在run.sh中，

supervisord -c /etc/supervisord.conf 

码头停止命令给我一个退出码-1。在查看日志时，似乎supervisord没有收到指示退出请求的SIGTERM。

2014-10-06 19:48:54,420 CRIT Supervisor running as root (no user in config file) 
2014-10-06 19:48:54,450 INFO RPC interface 'supervisor' initialized 
2014-10-06 19:48:54,451 CRIT Server 'unix_http_server' running without any HTTP authentication checking 
2014-10-06 19:48:54,451 INFO supervisord started with pid 6 
2014-10-06 19:48:55,457 INFO spawned: 'tomcat' with pid 9 
2014-10-06 19:48:56,503 INFO success: tomcat entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 

与之前收到sigterm并正常退出的日志相反。

2014-10-06 20:02:59,527 CRIT Supervisor running as root (no user in config file) 
2014-10-06 20:02:59,556 INFO RPC interface 'supervisor' initialized

2014-10-06 20:05:12,450 INFO stopped: tomcat (exit status 143) 

任何帮助表示赞赏。

当您运行通过run.sh的过程中，信号只发送到该进程。除非你是

1. 走出去的方式发送信号到子进程，例如，与陷阱
2. 发送信号到进程组。
3. 在run.sh

做exec supervisord ...子进程将无法获得信号。
