title: docker image build vs docker build
body: <p>Why does my Docker client recognize <code>docker build</code> but not <code>docker image build</code>? Is the client too old? Does CLI depends on client or server? 
  I believe I got my Docker client and server by installing the latest Docker toolbox.</p>

  $ docker image build
  docker: 'image' is not a docker command.
  See 'docker --help'.
  
  $ docker build
  "docker build" requires exactly 1 argument(s).
  See 'docker build --help'.
  
  Usage:  docker build [OPTIONS] PATH | URL | -
  
  Build an image from a Dockerfile
