尝试使用docker中的主管捕获我的应用程序的日志.

这是我的supervisord.conf：

[supervisord]
logfile=/dev/null
nodaemon=true
[program:autofs]
command=automount -f
redirect_stderr=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
[program:split-pdf]
command=bin/split-pdf-server
directory=/root/split-pdf
redirect_stderr=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0

启动容器后一切正常,我可以看到我的应用程序运行的结果(它在网络共享上创建pdf文件)

但是日志显示我的应用没有输出：

015-07-02 00:39:26,119 CRIT Supervisor running as root (no user in config file)
2015-07-02 00:39:26,124 INFO supervisord started with pid 5

2015-07-02 00:39:28,132 INFO success: autofs entered RUNNING state,process has stayed up for > than 1 seconds (startsecs)

这是我在附加到docker容器时看到的唯一输出.

我在ubuntu 15.04 docker 1.7.0上

这不是this question的副本,因为我在容器中运行多个进程.
