# build-docker-image.yml - Build a Docker image from another playbook
#
# Typical usage looks like:
#
#   ansible-playbook -i files/development-docker-images.yml \
#     -e arvados_build_playbook=FILENAME.yml \
#     [--limit=...] build-docker-image.yml
#
# `arvados_build_playbook` is the name of the playbook that turns a base image
# into a new image. The inventory defines container names, base images,
# and built image tags.
