我希望有一个码头图像：
- 运行乘客服务器和另一个守护进程以监控乘客服务器
- 一旦这两个进程中的任何一个进程退出一次，就要退出的容器
- 将所有日志指向stdout
在配置文件中，我放置了一个事件监听器（参考：https://serverfault.com/questions/760726/how-to-exit-all-supervisor-processes-if-one-exited-with-0-result/762406#762406），它捕获了passenger_monit程序的一些事件并执行脚本tt.sh。
我可以看到1个额外的passenger_monit程序实例在几次尝试后产生并达到FATAL状态。另一个passenger_monit和passenger_server都很好。其他乘客_monit的事件无法到达事件发生者。
这些脚本没有按预期工作：
这是supervisord.conf
[supervisord]
nodaemon=true
stdout_logfile=/dev/fd/1
redirect_stderr=true
stdout_logfile_maxbytes=0
[unix_http_server]

[supervisorctl]

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[program:passenger_monit]

command=./tt.sh
process_name=passenger_monit
events=PROCESS_STATE_STARTING,PROCESS_STATE_EXITED,PROCESS_STATE_FATAL
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
这是./script/passenger_monit.sh
#!/bin/bash
set -x
cd /passenger/newrelic_passenger_plugin/
# if exec is not put, then this process is not killed when supervisord exits
exec ./newrelic_passenger_agent
set +x
这是tt.sh
#!/bin/bash
echo "in tt!"
这是我运行的命令：
docker exec -it -u deploy 56bbbbe4352b supervisord
这是我得到的输出：

以下应能工作。请注意，10秒的脚本将在5秒后被杀死。
