PS: Deploy RHEL In Azure

Description:

So I had to deploy a set of RHEL 8 boxes in Azure but I kept being told to destroy them and move them between subnets. After the second time, I decided it would be better to script the installation. The following script will:

• Deploy RHEL 8 box to the Resource Group and Subnet of your choosing
• Attach an extra 80 GB disk to the VM
• Set the IP assigned to it as static (you will need to know the subnet and available IP Addresses before hand)
• Requires MS Az module

To Resolve:

1. Use the following script and set your variables in the Variables for each section:
