How to connect your library to real remote Linux docker?

I'm sorry, but your example don't describe how to connect to real docker environment.
In reality I can connect to docker with the same string

sudo curl --unix-socket /var/run/docker.sock http://157.XX.XX.84/v1.41/containers/json

I don't understand how to use your abstraction

client = new DockerClientConfiguration(new Uri("http://ubuntu-docker.cloudapp.net:4243")).CreateClient();

to simulate connection to real remote Linux docker with SUDO and Login/Password (from Linux and Windows)
