Just my two cents. So far it looks reasonable. Though I guess we could give
DOCKER_PARTIAL_IMAGES a better name or at least better documentation.
Would a per-arch variable list look cleaner? Like
DOCKER_IMAGES_GENERIC = debian
DOCKER_IMAGES_X86_64 = ubuntu fedora centos7
DOCKER_PARTIAL_IMAGES_X86_64 = ...
DOCKER_IMAGES_AARCH64 = ...
DOCKER_PARTIAL_IMAGES_AARCH64 = ...
Then the actual host arch can be used to expand rules:
docker-all-images: $(DOCKER_IMAGES_GENERIC)
docker-all-images: $(DOCKER_IMAGES_$(shell uname -m | tr '[a-z]' '[A-Z]))
