When checking the image-version on a raspberry pi it does not work:

root@RASPI2 ~ $ docker pull pihole/pihole
Using default tag: latest
latest: Pulling from pihole/pihole

CRITICAL: PiHole's version does not match registry

When I do the same on a amd64 system it shows different image-id and works without problems:

root@Ubuntu ~ $ docker pull pihole/pihole

Hi @timdaman I can confirm this. I also get a crit alarm on my raspi although I have the latest image.
