It’s possible solve containers by their container or service name, consider the following sample,
the container my-nginx can be solved by querying the hostname my-nginx.docker, the .docker domain is also
configurable by the domain configuration json property.
$ docker run --rm --name my-nginx nginx
$ nslookup my-nginx.docker
Server: 172.17.0.3
Address: 172.17.0.3#53
Non-authoritative answer:
Name: my-nginx.docker
Address: 10.0.2.3
