title: After providing DOCKER_HOST variable in docker the local image is not found
body: <p>I'm trying to run a docker container locally, and the image is also on my machine.</p>
  <p>I need to provide a DOCKER_HOST variable to my docker run command. However, once I provide it, my local image is not found. It was working before I started passing the DOCKER_HOST variable, and the image is still locally.</p>
  <p>I'm a docker beginner, so I am not sure how does the DOCKER_HOST variable affect the docker run command, or where does it look for the image now.</p>
  <p>This is the error message I get:</p>
  <pre><code>Unable to find image 'my_image:latest' locally
  docker: Error response from daemon: pull access denied for my_image, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
  </code></pre>
  <p>How can I solve the issue? Or how can I specify that the image can be found locally?</p>
