# Description
#  This script automates the creation of a WebLogic domain within a Kubernetes cluster.
#
#  The domain creation inputs can be customized by editing create-weblogic-domain-inputs.yaml
#
#  The following pre-requisites must be handled prior to running this script:
#    * The kubernetes namespace must already be created
#    * The kubernetes secrets 'username' and 'password' of the admin account have been created in the namespace
#    * The host directory that will be used as the persistent volume must already exist
#      and have the appropriate file permissions set.
