Answer 1

In my case, with docker version 1.13.0 and docker-machine 0.9.0 under Ubuntu 16.04 I had to modify slightly Tanzaho's answer (2. Modifying Docker config) as follows:

1. Log into Ubuntu as a user with sudo privileges.

2. Open the /etc/default/docker file for editing:

   sudo vim /etc/default/docker
   

3. Add the following setting for Docker.

   DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
   

4. Save and close the file.

5. Restart the Docker daemon :

   sudo service docker restart
