   === Image Source
   
  -Additional files can be provided to the build process via images.  Input
  -images are referenced in the same way the `From` and `To` image targets
  -are defined.  This means both docker images and image stream
  -tags can be referenced.  In conjunction with the image, you must provide one or
  -more path pairs to indicate the path of the files/directories to copy out of the
  -image and the destination to place them in the build context.
  -
  -The source path can be any absolute path within the image specified.  The destination
  -must be a relative directory path.  At build time, the image will be loaded
  -and the indicated files/directories will be copied into the context directory
  -of the build process.  This is the same directory into which the source repository
  -content (if any) is cloned.  If the source path ends in `*/.*` then the content
  -of the directory will be copied, but the directory itself will not be created
  -at the destination.

   Image inputs are specified in the `*source*` definition of the `*BuildConfig*`:
   
  
positive.code: commit because using the `--depth=1` option only works with named branch refs.
  
  If you want to perform a full Git clone of the `master` for the specified
  repository, you can set the `*ref*` to `master`.

negative.code: <6> An optional secret provided if credentials are needed to access the input image.
