# User can run the script like how they would execute the Shipyard CLI.
# For instance, to run the 'shipyard get actions' command, user can execute
# the following command after setting up the required environment variables:
#
# $ ./tools/run_shipyard.sh get actions
#

# NOTE: If user is executing the script from outside the cluster, e.g. from
# a remote jump server, then he/she will need to ensure that the DNS server
# is able to resolve the FQDN of the Shipyard and Keystone public URL (both
# will be pointing to the IP of the Ingress Controller). If the DNS resolution
# is not available, the user will need to ensure that the /etc/hosts file is
# properly updated before running the script.

# Define Variables
#
# NOTE: User will need to set up the required environment variables
# before executing this script if they differ from the default values.
