# This script publishes local duke-test-client:latest image to 10Duke internal
# Docker registry (docker-private.10duke.com:8443).
#
# Version is tagged and published with both "latest" and actual version number tags.
# Version number is read from package.json from the local duke-test-client:latest image.
# For example, if version number from package.json is 1.2.3, the following images are
# pushed to docker-private.10duke.com:8443:
#
# 10duke/duke-test-client:1.2.3
# 10duke/duke-test-client:latest
#
# docker login against docker-private.10duke.com:8443 is required before running this script.
