I’ve been following the Getting Started docs and there seems to be a very important step missing.
This page requires you to set up a docker repo or you’ll get a very unhelpful:
$ docker push banksysan/docker-whale The push refers to a repository [docker.io/banksysan/docker-whale] (len: 1) 654156f34320: Preparing unauthorized: access to the requested resource is not authorized
A discussion on what a repo and what a namespace is is needed. It looks like Docker repos are nothing liek Git repos (which confused me, and still does).
