Can I add the hash of docker container to my snapshot?

runtime {
docker: "imagename":HASH
memory: memGB
disks: "local-disk 256 HDD"
cpu: nCores

This would be useful for forcing versioning of the docker image in the snapshot.

    @ilya_at_vivid Yes, you can add a hash like so:
    docker: “broadinstitute/gatk:” where the is the hash.

    What if you have a tag and a hash?

    e.g. project/image:tag

    I had an error message with an "@hash after image name. Maybe that is the right format?

    @ilya_at_vivid I don't believe that you can implement the hash from a runtime attribute. When you refer to hash do you mean the container ID as if two different containers were built from the same docker image?

    Here is an example from a log file generated by terra. sha256 tag after the image name. I modified it to protect any identity. If a snapshot contained that hash you would guarantee that someone could not change the docker image in the snap shot. Right now I can just upload an image to a docker repository and the snap shot is no longer a "snap shot".
