Inside of the "shykes/pybuilder" image there is a command called buildapp, we are running that command and passing the $URL variable from step 2 to it, and running the whole thing inside of a new container. BUILD_JOB will be set with the new container_id. "1d9aab3737242c65" came from the output of step 1 when importing image. also available from 'docker images'.
