# 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

# make post-push-hook-all
#
# It's still possible to build, tag and push images manually. Just use:
# make release-all

# When Docker Hub triggers automated build all the tags defined in `post_push`
# hook will be assigned to built image. It allows to link the same image with
# different tags, and not to build identical image for each tag separately.
# See details:
# http://windsock.io/automated-docker-image-builds-with-multiple-tags

# Usage:
# make post-push-hook [DOCKERFILE=] [TAGS=t1,t2,...]
