Create a Windows virtual machine in Azure using Ansible

  • Artikkeli

This article shows how to deploy a Windows Server 2019 VM in Azure with Ansible.

In this article, you learn how to:

  • Create a resource group
  • Create a virtual network, public IP, network security group, and network interface
  • Deploy a Windows Server virtual machine
  • Connect to the virtual machine via WinRM
  • Run an Ansible playbook to configure Windows IIS

Prerequisites

  • Azure subscription: If you don't have an Azure subscription, create a free account before you begin.
  • Azure service principal: Create a service principal, making note of the following values: appId, displayName, password, and tenant.

Add WinRM Support to Ansible

To communicate over WinRM, Ansible control server needs the python package pywinrm.

Run the following command on the Ansible server to install pywinrm:

pip install "pywinrm>=0.3.0"

For more information, see Windows Remote Management for Ansible.

Create a resource group

Create an Ansible playbook named azure_windows_vm.yml and copy the following contents into the playbook:

---
- name: Create Azure VM
  hosts: localhost
  connection: local
  tasks:

  - name: Create resource group
    azure_rm_resourcegroup:
      name: myResourceGroup
      location: eastus

Key points:

  • Setting hosts to localhost and connection as _local_ runs the playbook locally on the Ansible server.

Create the virtual network and subnet

Add the following tasks to the azure_windows_vm.yml Ansible playbook to create a virtual network:

  - name: Create virtual network
    azure_rm_virtualnetwork:
      resource_group: myResourceGroup
      name: vNet
      address_prefixes: "10.0.0.0/16"

  - name: Add subnet
    azure_rm_subnet:
      resource_group: myResourceGroup
      name: subnet
      address_prefix: "10.0.1.0/24"
      virtual_network: vNet

Create a public IP address

Add the following tasks to the azure_windows_vm.yml playbook to create a public IP address:

  - name: Create public IP address
    azure_rm_publicipaddress:
      resource_group: myResourceGroup
      allocation_method: Static
      name: pip
    register: output_ip_address

  - name: Output public IP
    debug:
      msg: "The public IP is {{ output_ip_address.state.ip_address }}"

Key points:

  • Ansible register module is used to store the output from azure_rm_publicipaddress in a variable called output_ip_address.
  • The debug module is used to output the public IP address of the VM to the console.

Create network security group and NIC

Network security group defines what traffic is allowed and not allowed to reach the VM.

To open the WinRM and HTTP ports, add the following tasks to the azure_windows_vm.yml Ansible playbook:

  - name: Create Network Security Group
    azure_rm_securitygroup:
      resource_group: myResourceGroup
      name: networkSecurityGroup
      rules:
        - name: 'allow_rdp'
          protocol: Tcp
          destination_port_range: 3389
          access: Allow
          priority: 1001
          direction: Inbound
        - name: 'allow_web_traffic'
          protocol: Tcp
          destination_port_range:
            - 80
            - 443
          access: Allow
          priority: 1002
          direction: Inbound
        - name: 'allow_powershell_remoting'
          protocol: Tcp
          destination_port_range: 
            - 5985
            - 5986
          access: Allow
          priority: 1003
          direction: Inbound

  - name: Create a network interface
    azure_rm_networkinterface:
      name: nic
      resource_group: myResourceGroup
      virtual_network: vNet
      subnet_name: subnet
      security_group: networkSecurityGroup
      ip_configurations:
        - name: default
          public_ip_address_name: pip
          primary: True

Key points:

  • A virtual network interface card connects your VM to its virtual network, public IP address, and security group.
  • The azure_rm_securitygroup creates an Azure network security group to allow WinRM traffic from the Ansible server to the remote host by allowing port 5985 and 5986.

Create a virtual machine

Next create a virtual machine that uses all the resources you've created in the previous sections of this article.

Add the following task to the azure_windows_vm.yml Ansible playbook:

  - name: Create VM
    azure_rm_virtualmachine:
      resource_group: myResourceGroup
      name: win-vm
      vm_size: Standard_DS1_v2
      admin_username: azureuser
      admin_password: "{{ password }}"
      network_interfaces: nic
      os_type: Windows
      image:
          offer: WindowsServer
          publisher: MicrosoftWindowsServer
          sku: 2019-Datacenter
          version: latest
    no_log: true

The admin_password value of {{ password }} is an Ansible variable that contains the Windows VM password. To securely populate that variable, add a var_prompts entry to the beginning of the playbook.

- name: Create Azure VM
  hosts: localhost
  connection: local
  vars_prompt:
    - name: password
      prompt: "Enter local administrator password"
  tasks:

Key points:

  • Avoid storing sensitive data as plain text. Use var_prompts to populate variables at run time. Add no_log: true to prevent passwords from being log.

Configure the WinRM Listener

Ansible uses PowerShell to connect and configure Windows remote hosts via WinRM.

To configure WinRM, add the following ext azure_rm_virtualmachineextension:

  - name: Create VM script extension to enable HTTPS WinRM listener
    azure_rm_virtualmachineextension:
      name: winrm-extension
      resource_group: myResourceGroup
      virtual_machine_name: win-vm
      publisher: Microsoft.Compute
      virtual_machine_extension_type: CustomScriptExtension
      type_handler_version: '1.9'
      settings: '{"fileUris": ["https://raw.githubusercontent.com/ansible/ansible-documentation/devel/examples/scripts/ConfigureRemotingForAnsible.ps1"],"commandToExecute": "powershell -ExecutionPolicy Unrestricted -File ConfigureRemotingForAnsible.ps1"}'
      auto_upgrade_minor_version: true

Ansible can't connect to the VM until WinRM is fully configured.

Add the following tasks to your playbook to wait for the WinRM connection:

  - name: Get facts for one Public IP
    azure_rm_publicipaddress_info:
      resource_group: myResourceGroup
      name: pip
    register: publicipaddresses

  - name: set public ip address fact
    set_fact: publicipaddress="{{ publicipaddresses | json_query('publicipaddresses[0].ip_address')}}"

  - name: wait for the WinRM port to come online
    wait_for:
      port: 5986
      host: '{{ publicipaddress }}'
      timeout: 600

Key points:

  • The azure_rm_virtualmachineextension module allows you to run a PowerShell script locally on the Azure Windows. Running the ConfigureRemotingForAnsible.ps1 PowerShell script configures WinRM by creating self-signed certificates and opening the necessary ports for Ansible to connect.
  • The azure_rm_publicipaddress_info module queries the public IP address from Azure then set_fact stores the output in a variable for the wait_for module to use.

      name: nic
      resource_group: myResourceGroup
      virtual_network: vNet
      subnet_name: subnet
      security_group: networkSecurityGroup
      ip_configurations:
        - name: default
          public_ip_address_name: pip
          primary: True

      auto_upgrade_minor_version: true

  - name: Get facts for one Public IP
    azure_rm_publicipaddress_info:
      resource_group: myResourceGroup
      name: pip
    register: publicipaddresses

  - name: set public ip address fact
    set_fact: publicipaddress="{{ publicipaddresses | json_query('publicipaddresses[0].ip_address')}}"

  - name: wait for the WinRM port to come online
    wait_for:
      port: 5986
      host: '{{ publicipaddress }}'
      timeout: 600

Connect to the Windows virtual machine

Create a new Ansible playbook named connect_azure_windows_vm.yml and copy the following contents into the playbook:

---
- hosts: all
  vars_prompt:
    - name: ansible_password
      prompt: "Enter local administrator password"
  vars:
    ansible_user: azureuser
    ansible_connection: winrm
    ansible_winrm_transport: ntlm
    ansible_winrm_server_cert_validation: ignore
  tasks:

  - name: Test connection
    win_ping:

Run the Ansible playbook.

ansible-playbook connect_azure_windows_vm.yml -i <publicIPaddress>,

Replace <publicIPaddress> with your virtual machine's address.

Key points:

  • Ansible's configuration determines how Ansible connects and authenticates to remote hosts. The variables you need to define to connect to a Windows host depend on your WinRM connection type and the authentication option you've chosen. For more information, see Connecting to a Windows Host and Windows Authentication Options.
  • Adding a comma after the public IP address bypasses Ansible's inventory parser. This technique allows you to run playbooks without an inventory file.

Clean up resources

  1. Save the following code as delete_rg.yml.

    ---
- hosts: localhost
  tasks:
    - name: Deleting resource group - "{{ name }}"
      azure_rm_resourcegroup:
        name: "{{ name }}"
        state: absent
      register: rg
    - debug:
        var: rg

  2. Run the playbook using the ansible-playbook command. Replace the placeholder with the name of the resource group to be deleted. All resources within the resource group will be deleted.

    ansible-playbook delete_rg.yml --extra-vars "name=<resource_group>"

    Key points:

    • Because of the register variable and debug section of the playbook, the results display when the command finishes.
