Logs are not sent to STDOUT

I've encountered two loosely coupled issues and am interested in contributing to their resolution.

1. Maxscale Docker images no longer log to stdout after version 2.5.X (difficult to determine, see follow up issue). This is obviously problematic, as this is how Docker aggregates logs. A brief investigation determined that this was due to an entrypoint script.

   [root@0db4086c260e /]# ps -ewwf

   UID PID PPID C STIME TTY TIME CMD

   root 1 0 0 Jan05 ? 00:01:16 /usr/bin/tini -- docker-entrypoint.sh /bin/sh -c maxscale-start && monit -I

   [root@0db4086c260e /]# cat /usr/bin/docker-entrypoint.sh

   #!/bin/bash

   function exitMaxScale {

   /usr/bin/monit unmonitor all

   /usr/bin/maxscale-stop

   /usr/bin/monit quit

   }

   rm -f /var/run/*.pid

   rsyslogd

   trap exitMaxScale SIGTERM

   exec "$@" &

   wait

   To the best of my understanding, this exists to triage maxscale into a multi-process container (monit managing maxscale and rsyslog). I am not familiar with rsyslog, and consequently cannot comment on its necessity, but ideally logs are sent to stdout to re-enable process logging.

2. Upon discovery of the aforementioned issue, I began to investigate the github repository to find additional information (e.g. when rsyslog was introduced, its purpose, etc.). My first stop was to identify when the new entrypoint was defined, as that would provide the most contextual information. However, the Dockerfile presented within the repository hasn't been updated in four years (version 2.2). Consequently, it is difficult to perform further investigative efforts or contribute to the project.

Please advise on how I should proceed.
