I am trying follow the instructions in https://github.com/blockstack/blockstack-core/blob/master/docs/namespace_creation.md#setting-up-the-test-environment
in order to to set up a test environment.
Ultimately, I’d like understand how to script registering a namespace via API.
Here is the command I ran and the output I got:
$ docker pull quay.io/blockstack/integrationtest:develop Error response from daemon: unauthorized: access to the requested resource is not authorized
