AbsToRelPath is a helper method for converting absolute paths to paths relative to the present working directory This is due to Docker requiring relative paths when building.

ImageBuild takes a DockerArtifact and uses the Docker daemon for building.

ParseBuildArgsFromFlag writes args from a flag string array to a map Example input: []string{"VERSION=1.8.0", "LANG=Go", "BUILDER=Docker"}.

PrintStream decodes the Docker output from io.Reader and outputs it to the io.Writer.

Stream is used by Docker for communicating event responses.

StreamError defines an error that occured during a Docker event.
