Deploying multiple VM's with ansible - azure

Question

I'm learning ansible to create Linux VM's on azure and I used this sample playbook in this link (https://learn.microsoft.com/en-us/azure/developer/ansible/vm-configure?tabs=ansible) to create one VM on azure. If I want to deploy 10 VM's exactly like this with ansible-playbook how should I do it? Please help. Thanks in advance
Update: I tried it like this but the script fails after creating two public IP addresses.
- name: Create Azure VM
hosts: localhost
connection: local
tasks:
- name: Create resource group to hold VM
azure_rm_resourcegroup:

You can use the loops function to create multiple VMs through ansible as you showed in the question, but you'd better use a list variable to loop so that you don't need to write all the elements every time. And the variables also can be used for other things like resource group name, location, and so on that use multiple times in the code. Here is the example:
- hosts: localhost
vars:
resource_group: myResourceGroup
...
tasks:
- name: Create resource group to hold VM
azure_rm_resourcegroup:
name: "{{ resource_group }}"
location: eastus
...
And the variable for the loop:
loop: "{{ var_list }}"

I found out it's quite easy with terraform to deploy multiple VM's on azure just by changing one variable in the configuration file, Here's the configuration file that i used (https://github.com/RichardPhilipsRoy/terraform-azure-linuxVMs)
