How to set a default registry to pull from in docker machine?

I have docker machine and by default it pulls my images from docker hub. Now we have our own repo which can serve as a remote proxy to docker hub. We can pull with docker pull server/repo/image.

Now I want that docker pull image resolves to our registry instead of docker hub. How can I achieve this in docker machine?

Solution

Changing the default docker registry is not possible. You can only configure a private registry to act as a mirror for the dockerhub registry as documented in Registry as a pull through cache.
