Kill supervisor on Docker when any of the services fail

Killing supervisor if any of it's child processes fail

The trick is to only register the listener for events that indicate failure, namely

  • PROCESS_STATE_STOPPED
  • PROCESS_STATE_EXITED
  • PROCESS_STATE_FATAL

Once they do, we should send a SIGQUIT to Supervisor.

#!/bin/bash
printf "READY\n";
while read line; do
echo "Processing Event: $line" >&2;
kill -3 $(cat "/var/run/supervisord.pid")
done < /dev/stdin
[supervisord]
nodaemon=true
loglevel=debug
logfile=/var/log/supervisor/supervisord.log
pidfile=/var/run/supervisord.pid
childlogdir=/var/log/supervisor
[program:nginx]
command=nginx -g "daemon off;"
redirect_stderr=true
[program:php-fpm]
command=php-fpm
redirect_stderr=true
[eventlistener:processes]
command=stop-supervisor.sh
events=PROCESS_STATE_STOPPED, PROCESS_STATE_EXITED, PROCESS_STATE_FATAL
