auto-reload supervisord config on changes

autoreload_supervisor.sh

#!/bin/sh
# auto-reload supervisor config on a config file change
# Licensed under Public Domain

# apt-get install inotify-tools

while true; do
    inotifywait --quiet --recursive --event create,close_write /etc/supervisor/
    supervisorctl reread
    supervisorctl update
done

In WSL 2 Docker container inotify is not working I'm not sure why/how to fix this just yet but it should be fixed in future versions.
For now I will just poll an md5 of the config sharing here in-case it helps anyone. Cheers for the example @DerMitch

FILE="/etc/supervisor/conf.d/supervisord.conf"
LAST=`md5sum "$FILE"`
while true; do
  sleep 1
  NEW=`md5sum "$FILE"`
  if [ "$NEW" != "$LAST" ]; then
    supervisorctl reread
    supervisorctl update
    LAST="$NEW"
  fi
done
