Similar to the question \"What´s the sha256 code of a docker image?\", I would like to find the digest of a Docker image. I can see the digest when I download an image:
I encountered a task recently that required viewing the sha256 digest without necessarily pulling the image. The tool skopeo makes the registry API calls so you don't need to pull the image.
For example,
$ skopeo inspect --creds "username:password" docker://waisbrot/wait:latest
You could then pipe this to jq
if you want to get just the digest value.
$ skopeo inspect --creds "username:password" \
docker://waisbrot/wait:latest | jq -r '.Digest'
sha256:6f2185daa4ab1711181c30d03f565508e8e978ebd0f263030e7de98deee5f330
