# with incrementing names (vm-1, vm-2, vm-3 etc) 
# set all variables, log in to az-cli with 'az login' and run the script.

# The public IPs of the VMs are out printed out 
# at the bottom of the prompt when the operation is complete

# Variables
 vmcount=""					# amount of VMs you want to create
 resourcegroup=""	# Resource Group
 vmname=""					# Name of Virtual Machine, becomes "name-1".."name-30", depends on the number in $vmcount

 netsecgroup=""			# Network Security Group
 nsgrule="ssh"					# Can be "ssh" or "rdp"
 subnetname=""		# Subnet Name
 loc=""				# Location (west europe, west us, etc.)
 virtualnetwork=""		# Virtual Network Name
 admuser=""				# Admin Username
 sshkeyloc=""	# Location of ssh key file
 os=""					# Operating System
