      Docker v1.10.0 introduced a new format for image IDs whereby they now have a prefix of sha256: before the hash. See https://github.com/docker/docker/pull/17924 under Summary of UI Changes:

      Full-length image IDs have a sha256: prefix. This prefix is hidden for truncated image IDs for convenience.

      This is causing my jobs that rely on building and pushing Docker images to fail. It builds the image fine, but when it goes to push it to the repository it apparently first validates the image ID by making sure it's a string with a length of 64. The length check is now failing, since the full image ID now contains the sha256: prefix.

      The relevant file and line where this check is occurring is /src/main/java/org/jenkinsci/plugins/docker/commons/fingerprint/DockerFingerprints.java#L64

      The error in my build log is:

      Successfully built 8d6d5e96d600
      [api-dev] $ docker inspect 8d6d5e96d600

      I'm not sure what the usefulness of the length check is, but it should either be removed or updated to account for the new prefix in the full image ID.
