Automating with Ansible

Example Playbook for Preparing Windows Installation

This playbook downloads the Windows ISO file and creates bootable installation media.

- name: Prepare Windows installation media
  hosts: localhost
  tasks:
    - name: Download Windows ISO
      ansible.builtin.get_url:
        url: "https://software-download.microsoft.com/ISO_URL"
        dest: "/tmp/windows.iso"
- name: Create bootable USB
      ansible.builtin.shell: >
        dd if=/tmp/windows.iso of=/dev/sdX bs=4M status=progress

Example Playbook for Installing Windows Using a Pre-Configured Answer File

Use an answer file to automate Windows setup.

- name: Automate Windows installation
  hosts: windows_servers
  tasks:
    - name: Upload answer file to target
      ansible.windows.win_copy:
        src: "/path/to/answer_file.xml"
        dest: "C:\\Windows\\Panther\\unattend.xml"
- name: Reboot and boot into setup
      ansible.windows.win_reboot:
        msg: "Rebooting to start Windows installation"
        reboot_timeout: 600

Example Playbook for Post-Installation Configuration

Configure the newly installed Windows system.

- name: Configure Windows after installation
  hosts: windows_servers
  tasks:
    - name: Set hostname
      ansible.windows.win_hostname:
        name: "NewWindowsHost"
- name: Configure Windows Update settings
      ansible.windows.win_updates:
        category_names:
          - SecurityUpdates
          - CriticalUpdates
        reboot: yes
- name: Install essential software
      ansible.windows.win_package:
        path: "C:\\installers\\software_installer.msi"
        state: present
