 Edit the variables below by replacing `CLUSTERNAME`, `ADMINPASSWORD`, `NEWUSER`, and `USERPASSWORD` with the appropriate values. The script is designed to be executed with bash. Slight modifications would be needed for a Windows command prompt.
 
 ```bash
-export clusterName="CLUSTERNAME"
-export adminPassword='ADMINPASSWORD'
-export user="NEWUSER"
-export userPassword='USERPASSWORD'
+export CLUSTER_NAME="CLUSTERNAME"
+export ADMIN_PASSWORD='ADMINPASSWORD'
+export USER="NEWUSER"
+export USER_PASSWORD='USERPASSWORD'
