moby: Embedded dns server breaks DIND

$ docker exec dind cat /etc/resolv.conf
search domain.local
nameserver 127.0.0.11
options ndots:0

$ # prove that network and dns connectivity work for other commands

$ docker exec dind ping -c1 google.com

I have the same issue. I am using consul dns server using the startups options -recursor=8.8.8.8 -recursor=8.8.4.4"

My /etc/resolv.conf look like this :

domain myapp.com
search myapp.com consul
nameserver 192.168.1.4

If I change my /etc/resolv.conf nameserver to 8.8.8.8 I can pull the image, otherwise, I keep having this error :

Unable to find image 'ubuntu:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/ubuntu/manifests/latest: Get https://auth.docker.io/token?account=kopax&scope=repository%3Alibrary%2Fubuntu%3Apull&service=registry.docker.io: dial tcp: lookup auth.docker.io on 192.168.1.4:53: no such host.

However, if I am pulling from a private docker registry, it does work without having to do any change. I really don’t understand how I should debug this issue.
