Subject: [PATCH] Update default docker.io registry

This commit updates the default endpoint for DockerHub to be
`index.docker.io`. This is the default endpoint that the Docker CLI is
using.

Running `docker info`, this is the endpoint returned for the registry:

```
$ docker info | grep Registry
 Registry: https://index.docker.io/v1
```

This means we can now push references to
`index.docker.io/user/repo:tag`.
