title: Pulling from local registry gives UNAUTHORIZED
body: <p>I am running a Docker registry in a container which I run as-is from the image of 'docker-registry', as published on Docker hub. This image is running on a machine in my local network. From my laptop I am able to push an image to that registry without any problems. I subsequently try to pull that same image to a different machine on my network, but there I get an error response:
  <code>{&quot;code&quot;:&quot;UNAUTHORIZED&quot;,&quot;message&quot;:&quot;authentication required&quot;, ...}</code>
  This raises the questions: Is this image configured to require authentication? Why does it not require authentication when I push/pull from my laptop?</p>
