-# Docker Hub expects an existing ready-to-use Dockerfile, and this hook allows

-# ----------------------------------------------------------------------------------------

-#  - DOCKERFILE_PATH: the filename defined as "Dockerfile Location"
-#  - SOURCE_REPOSITORY_URL: the url of the repo triggering the tag event
-#  - SOURCE_COMMIT: the sha1 of the commit triggering the tag event
