title: Docker official registry (Docker Hub) URL
body: <p>Docker Hub official website has been moved to <a href="https://registry.hub.docker.com" rel="nofollow noreferrer">https://registry.hub.docker.com</a> from <a href="https://hub.docker.com/" rel="nofollow noreferrer">https://hub.docker.com/</a>.</p>
  <p>If I try to <code>docker pull</code> images from URL like: <code>docker pull registry.hub.docker.com/busybox </code> it shows:</p>
  <pre><code>registry.hub.docker.com/busybox: this image was pulled from a legacy registry.  
  Important: This registry version will not be supported in future versions of docker.
  </code></pre>
  <p>But if I use <code>docker pull registry.hub.docker.com/busybox</code>.</p>
  <p>It cannot pull the image.</p>
  <p>Same situation when using <code>curl -k https://registry.hub.docker.com/v1/repositories/busybox/tags</code></p>
  <p>UPDATE AS of 2022 / Q3:
  use docker.io
  example docker.io/nginx</p>
