# This script contains the helper functions that each provider hosting
# Kubermark must implement to use test/kubemark/start-kubemark.sh and
# test/kubemark/stop-kubemark.sh scripts.

# This function should authenticate docker to be able to read/write to
# the right container registry (needed for pushing kubemark image).

# This function should create kubemark master and write kubeconfig to
# "${RESOURCE_DIRECTORY}/kubeconfig.kubemark".
# If a cluster uses private master IP, create-kubemark-master might also write
# a second kubeconfig to "${RESOURCE_DIRECTORY}/kubeconfig-internal.kubemark".
# The difference between these two kubeconfigs is that the internal one uses
# private master IP, which might be better suited for setting up hollow nodes.
