Docker 17.05.0 Adds Multi-Stage Build and Ubuntu 17.04 (Zesty Zapus) Support

Prominent new features of the Docker 17.05.0 release include support for building Docker DEB packages for Ubuntu 17.04 (Zesty Zapus) machines on the 64-bit (amd64) architecture, multi-stage build support to the builder, along with a new option that lets users specify build targets, and support for using build-time args (ARG) in FROM. The client received a bunch of new command-line options, including the “–mount” for the “docker run” and “docker create” commands, “–type=secret” for “docker inspect”, “–format” and “–filter” for “docker secret ls”, “–filter scope=” for “docker network ls”, and “–cpus” for “docker update.”
