In Docker, is there a way to retrieve the image or layer UUID?

I am looking for a way to retrieve the docker container image UUID and the layers UUID. I saw the command 'docker images' and 'docker history' but they do not work on the individual image. Is there a command to do this?

This is how I did it with a running image: $ docker exec youthful_pike cat /sys/class/dmi/id/product_uuid E2F747AF-0000-0000-AA77-B856C9D179D8

You can find some more information about an image if your perform the following commands:

$ docker images 

mysql                                           latest              2fd136002c22        8 weeks ago         378.4 MB

inspect the imageID or image name

$ docker inspect 2fd136002c22

output:

"RootFS": {
            "Type": "layers",
            "Layers": [
                "sha256:4dcab49015d47e8f300ec33400a02cebc7b54cadd09c37e49eccbc655279da90",
                "sha256:5f70bf18a086007016e948b04aed3b82103a36bea41755b6cddfaf10ace3c6ef",
                "sha256:47bce276c5783a6cfc88e0ac368af70909144d04780222d134090dbf08f897aa",
                "sha256:5f70bf18a086007016e948b04aed3b82103a36bea41755b6cddfaf10ace3c6ef",
                "sha256:093c117bc4d3e1cd6e597a89b1648ebb3543be581c61aba80fc41ff6f7ae8e6d",
