See Spaceinvader One's setup video here:        I wrote the template that pulls in the Official Docker Container from PiHole. I swapped over from my unofficial one a long time ago that that a fully supported version could be distributed. Make sure that your repository for pihole is = pihole/pihole:latest and not the old diginc repository. If you use the latest tag, you should have v 4.0.0-1. The release tags are here: https://hub.docker.com/r/pihole/pihole/tags
