Azure – CLI – Build Windows/UNIX VM Function (With or without public IP)

In the functions below the VM name is used in all of the pieces to build the VM to simplify documentation.

Important Items:

1. As I use a Firewall appliance in Azure I do not set Network Security Groups (NSG).
2. I have a predefined virtual network (VN) and predefined network subnet configuration (NSC)
3. UnixAdmin user is created with a SSH key instead of password so saving the key will be needed
4. WindowsAdmin user is created with a password that you will want to change before you run the function or after your first login
5. Windows VM has an option for additional data disks, this could be added to the UNIX VM function as well, the size in GB is not configurable currently via the function so you may want to change the values or add it to the function
6. Some variables could be created to replace items I’ve predefined
