#
# This script copies Docker images from the local Docker registry into Minishift VM's one.
#
# This is done by saving local images to /tmp/kapua-containers-{someRandomness}/ using command:
#     docker save -o /tmp/kapua-containers-{someRandomness}/{outputFileName} {sourceImageName}
#
# Then sets Minishift Docker registry overriding environment variables:
#     DOCKER_CERT_PATH=~/.minishift/certs
#     DOCKER_HOST=tcp://192.168.99.100:2376
#     DOCKER_TLS_VERIFY=1
#
# And loading into the registry by running:
#     docker load < /tmp/kapua-containers-{theSameRandonessAsBefore}/{outputFileName}
#
