Docker PiHole Persistence - post_main.d/start_pi_hole.sh Error

I finally got PiHole to run in a docker after resetting docker and using the updated yaml file. But once I reboot the firewalla the pihole doesn't appear to be accessible on network until I reset docker and start again. I'm not really sure how to troubleshoot this particular issue, Pihole is currently running as I've reset it so maybe that is reason for this error but if I 'sh start_pi_hole.sh' then I get this output...
root@firewalla:/home/pi/.firewalla/config/post_main.d# sh start_pi_hole.sh
Failed to start docker\x0d.service: Unit docker\x0d.service not found.
