How is a Docker Machine marked as active?

Question

I am working through the Docker Machine User Guide over at https://docs.docker.com/v1.5/machine/.

It says:

You can see the machine you have created by r         


        

Answer 1

I think just running the following command should work:

$ eval $(docker-machine env default)

(Where default is the name of the machine).

The reason for the * is to tell you which machine you're currently connected to e.g. if you run docker ps which Docker engine will it talk to?

In the current version of Docker machine, I believe you have to always specify the name.
