title: How to set image stored path in docker registry?
body: <p>I'm new to docker, and I want to config my local docker registry. So I use the command:</p>
  
  <pre><code>docker run -d -p 5000:5000 -e REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/opt/scs/v11/docker_registry --restart=always --name registry registry
  </code></pre>
  
  <p>Then,I use the command to push the image to registry:</p>
  
  <pre><code>docker pull ubuntu&amp;docker tag ubuntu localhost:5000/batman/ubuntu
  docker push localhost:5000/batman/ubuntu
  </code></pre>
  
  <p>I think it will store the image in /opt/scs/v11/docker_registry,But I can't find anything in this file path. I want to know where are my pushing image?
  How should I do if I want to store image in special file path?</p>
