The repository with Dockerfile is publich here:

https://github.com/isc-projects/bind9-docker/blob/v9.20/Dockerfile

We are happy to review and incorporate improvements - it's open-source!

Having said that, I wonder if people have some preference or even policy 
which mandates specific base image?

Alpine is popular for small images, but is it good enough in "one size 
fits all" sense?
