Ian Campbell 5894bc1abf Add docker build --iidfile=FILE ... This is synonymous with `docker run --cidfile=FILE` and writes the digest of the newly built image to the named file. This is intended to be used by build systems which want to avoid tagging (perhaps because they are in CI or otherwise want to avoid fixed names which can clash) by enabling e.g. Makefile constructs like: image.id: Dockerfile docker build --iidfile=image.id . do-some-more-stuff: image.id do-stuff-with <image.id Currently the only way to achieve this is to use `docker build -q` and capture the stdout, but at the expense of losing the build output. In non-silent mode (without `-q`) with API >= v1.29 the caller will now see a `JSONMessage` with the `Aux` field containing a `types.BuildResult` in the output stream for each image/layer produced during the build, with the final one being the end product. Having all of the intermediate images might be interesting in some cases. In silent mode (with `-q`) there is no change, on success the only output will be the resulting image digest as it was previosuly. There was no wrapper to just output an Aux section without enclosing it in a Progress, so add one here. Added some tests to integration cli tests.
