Create Harbor Server on Ubuntu VM

#kubernetes
Copy this script on your Ubuntu VM and update first user inputs section for IP, hostname and FQDN. I tested this script on Ubuntu 22.
# This script will install Harbor server 
# 

#  User Inputs
> #==================================================
> export my_hostname=<Harbor server short host name>
export my_fqdn=<Harbor server FQDN>
export my_ip=<IP Address of the Harbor server>
#==================================================

read -n 1 -r -s -p $'Press enter to continue... else Control + c to stop \n'

    echo "$message" >&2
    exit 1
