title: How can I find a Checksum of a Docker Image
body: <p>I'm using Docker 1.10.3.</p>
  
  <p><a href="https://github.com/docker/docker/blob/master/image/spec/v1.md" rel="noreferrer">Docker Image Specification v1.0.0</a> says there is an Image Checksum field in a Docker Image JSON Description, like:</p>
  
  <pre><code>"checksum": "tarsum.v1+sha256:e58fcf7418d2390dec8e8fb69d88c06ec07039d651fedc3aa72af9972e7d046b",
  </code></pre>
  
  <p>However, there is no such a field in the result of <code>docker inspect &lt;IMAGE&gt;</code>.</p>
  
  <p>How can I get the checksum of a particular image?</p>
