# Note:
# - docker images are not necessarily rebuild if they exist but are outdated.
#   To force rebuild you have two options
#   - do a 'make clobber' first. This ensures you will have the uptodate images
#     but is a broad and slow brush
#   - to just fore rebuilding an image, call `make` with DOCKER_FORCE_REBUILD defined
#   - to keep docker build quiet unless there is an error, call `make` with DOCKER_QUIET_BUILD defined
