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.

Engine API version history Documentation of changes that have been made to Engine API. API, Docker, rcli, REST, documentation

v1.30 API changes

Docker Engine API v1.30 documentation

  • GET /info now returns the list of supported logging drivers, including plugins.

Docker Engine API v1.29 documentation

  • DELETE /networks/(name) now allows to remove the ingress network, the one used to provide the routing-mesh.
  • POST /networks/create now supports creating the ingress network, by specifying an Ingress boolean field. As of now this is supported only when using the overlay network driver.
  • GET /networks/(name) now returns an Ingress field showing whether the network is the ingress one.
  • GET /networks/ now supports a scope filter to filter networks based on the network mode (swarm, global, or local).
