       Host machine DNS for Docker Containers
Starting installation process

Eventually you will be asked for you password to perform "sudo" steps.
Please inform the container's name for docker-dns. That container is used to communicate from host machine

to Docker environment.

Container's name: [ns0]

Now inform the container's image tag name: [ns0]

And now inform the top level domain you would like to use for containers name resolution.

For example, for "ns0.docker" please inform "docker". If you prefer "ns0.dev" please inform "dev".

Top level domain:  [docker]
Please confirm the information below

Container name: ns0

Image tag name: ns0

Working domain: docker

Is that correct? [y/N] y
