 - create a new namespace in your kubernetes cluster called sock-shop and deploy multiple containers to it \n

 You can review this test sock-shop deployment code at: https://github.com/microservices-demo/microservices-demo \n 
 If you already have a namespace called sock-shop or do not want to create it and deploy containers to your solution, stop execution of this script by entering the letter N or simply hitting enter. If you are happy for this script to create a namespace called sock-shop, type in uppercase Y. \n\n "
