As soon as the Docker file included any line

Answer 1

Same issue for me (on Ubuntu Xenial).

• docker run --dns ... for containers worked.
• Updating docker daemon options for docker build (docker-compose etc.) did not work.

After analyzing the docker logs (journalctl -u docker.service) if found some warning about bad resolvconf applied.

Following that i found that our corporate nameservers were added to the network interfaces but not in resolvconf.

Applied this solution How do I configure my static DNS in interfaces? (askubuntu), i.e. adding nameservers to /etc/resolvconf/resolv.conf.d/tail

After updating resolvconf (or reboot).

bash docker run --rm busybox nslookup google.com

worked instantly.

All my docker-compose builds are working now.
