I'm using Docker 1.10.3.

[Docker Image Specification v1.0.0](https://github.com/docker/docker/blob/master/image/spec/v1.md) says there is an Image Checksum field in a Docker Image JSON Description, like:

```
"checksum": "tarsum.v1+sha256:e58fcf7418d2390dec8e8fb69d88c06ec07039d651fedc3aa72af9972e7d046b",

```

However, there is no such a field in the result of `docker inspect <IMAGE>`.

How can I get the checksum of a particular image?
