What's the default url that docker using when run `docker pull`?

I've searched a lot but still can't get the accurate answer of this question:

What's the default url that docker using when run docker pull? (Especially the /v2 one)

I've see several urls from log or some documents:

  1. http://index.docker.io
  2. http://registry.hub.docker.com
  3. http://registry-1.docker.io

But I'm not sure which one is correct, and what's the purpose of the others

Those 3 urls are there for different purposes:

http://registry.hub.docker.com is the Docker web site for listing the image.
It is not where those images are actually stored.

As the Nexus Docker settings details:

This is a service issue, not related to the docker engine project.
Amazon S3 is experiencing some problems.

  • https://index.docker.io/ is the docker index, used for requests related to searches, users, docker tokens and other aspects.

To quote man docker-pull:

If you do not specify a REGISTRY_HOST, the command uses Docker's public registry located at registry-1.docker.io by default.

I don't think you can get more official than that.
