Build docker container with dynamic tag

	# This step generates an image tag based on git tree hash of the source folder so
	# the tag changes whenever your source changes and will trigger new builds/pulls.
	# If the image is tracking an upstream app, I'll add a "{{ base_tag }}-" prefix
	# so I get a new image if the source version changes but my wrapper does not.

	# This can be hidden in vars/main.yml to avoid a dedicated step
	- set_fact:
	# Extracted for shorter lines - this command assumes the parent directory to
	# roles/ is the root of a git repository.
