title: Docker Hub: How do I pull an older version of a 3rd party image?
body: <p>How do I pull an older build of a 3rd party image from Docker Hub?</p>
  
  <p>For example I would like to pull <a href="https://hub.docker.com/r/appropriate/curl/builds/b4f8nqnmaypvwmshyvzcesk/" rel="noreferrer">this build</a> of appropriate/curl.</p>
  
  <p>I've tried using the "Build Code" as the tag, as well as the partial SHA256 of the image shown at the end of the build, and neither work.</p>
  
  <p>Note: this is different from <a href="https://stackoverflow.com/questions/25445318/docker-how-do-i-pull-a-specific-build-id">Docker: How do I pull a specific build-id?</a> since the author of that question is able to fork the version and tag their own builds as a workaround. I'm trying to access something that was built in the past (to analyze a regression).</p>
