# This Makefile automates possible operations of this project.
#
# Images and description on Docker Hub will be automatically rebuilt on
# pushes to `master` branch of this repo and on updates of parent images.
#
# Note! Docker Hub `post_push` hook must be always up-to-date with values
# specified in current Makefile. To update it just use:
# make post-push-hook-all
#
# It's still possible to build, tag and push images manually. Just use:
# make release-all
