# 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

    # Extracted for shorter lines - this command assumes the parent directory to
    # roles/ is the root of a git repository.
