# 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).
function authenticate-docker {

# This function should get master IP address (creating one if needed).
# ENV vars that should be defined by the end of this function:
# - MASTER_IP
#
# Recommended for this function to include retrying logic in case of failures.

# This function should create a machine instance for the master along
# with any/all of the following resources:
# - Attach a PD to the master (optionally 1 more for storing events)
# - A public IP address for the master ($MASTER_IP)
# - A network firewall rule allowing all TCP traffic on port 443 in master
#   Note: This step is compulsory in order for kubemark to work
#
# ENV vars that should be defined by the end of this function:
# - MASTER_NAME
#
# Recommended for this function to include retrying logic for the above
# operations in case of failures.

# (possibly through SSH), retrying in case of failure. The allowed number of
# retries would be '$2' (if not provided, default to single try).
