# Structure of the makefile
#
# We have generic targets (run pull build clean), wich
# depend on the image's specific target
#
# Every docker image flavor has a unique name. It is used as
# the docker repository's tag and the tag is encoded in the
# target's name, whenever the target is image-specific.
#
# Every target is constructed by `ci-<action>-<flavor>`,
# which actually build/pull/run the single docker image.
#
# The image names for the flavors are found in the variable
# IMG_CI, which is automatically filled (if unset) by the
# Dockerfiles in the ci folder.

IMG_CI?=$(shell find ci -name 'Dockerfile.*' | sed 's/ci\/Dockerfile\.\(.*\)/\1/')
# force make to execute the find call only once
