Ansible playbooks to deploy a Windows AD DC Lab in GNS3 with QEMU

The main goal is to have a working AD DC Lab in a GNS3 with QEMU.

Ansible helps us to automate this task.

Do not use it in production. Only for testing and learning purposes.

Windows QEMU image

Image used: Windows Server 2022 rgl/windows-vagrant images

Always "sysprep" a Windows image before use:

C:\Windows\System32\Sysprep\sysprep.exe /generalize /shutdown /oobe /quiet

This image is ready to be deployed on the GNS3 server.

Scenario

Scenario based on: rgl/windows-domain-controller-vagrant

Value added:

GNS3 toplogy
Ansible playbook

A Domain Controller and two Windows workstations are added in the osseclab GNS3 topology :

In this topology a router named "gateway" acts as an IPv4 Internet Gateway and DHCP/DNS server for the "EXAMPLE.COM" domain. The blue connections are the IP Network segments adressed in 192.168.1.0/24 and in 192.168.2.0/24. Dotted lines are connected to a management switch with a controller that distributes 11.12.13.0/24 management addresses.

How to use

Setup the controller (Centos):

curl -s https://raw.githubusercontent.com/goffinet/ansible-ccna-lab/master/tests/setup-controller.sh -o controller_setup.sh
bash controller_setup.sh
reboot

Install all requirements on this Centos host:

yum -y install git
git clone https://github.com/goffinet/ansible-windows-dc
cd ansible-windows-dc
bash -x ansible_setup.sh

Look at the inventory:

inventory/
├── group_vars
│   ├── all
│   └── domain_controllers
└── hosts

Look at the main inventory file inventory/hosts:

[domain_controllers]
dc ansible_host=11.12.13.117 ip_address=192.168.1.99 ip_gateway=192.168.1.1

dns_domain_name="example.com"
domain_netbios_name="EXAMPLE"
domain_dn="DC=example,DC=com"
main_password="HeyH0Password"

AD users list is stored in the inventory/domain_controllers:

domain_users:
  - firstname: "john"
    surname: "doe"
    password: "{{ main_password }}"
    password_never_expires: yes
    groups:
      - "Domain Admins"
  - firstname: "jane"
    surname: "doe"
    password: "{{ main_password }}"
    password_never_expires: yes
    groups:
      - "Domain Admins"
managed_sa: sa_test

Look at the site.yml playbook:

---
- import_playbook: playbooks/setup_domain_controller.yml
- import_playbook: playbooks/configure_domain_controller.yml
- import_playbook: playbooks/setup_windows_workstations.yml
- import_playbook: playbooks/install_chocolatey.yml
- import_playbook: playbooks/setup_linux.yml

Usage:

Start the machines
For Windows hosts:
- Start a first session in a locale console (VNC)
- Get the IP management address (cmd.exe / ipconfig / logoff) in the 11.12.13.0/24 range
- Update the inventory ansible_host variable for each windows hosts
Test the ansible "winrm" connection:
```
ansible -m win_ping windows
```

Test the ansible "ssh" connection:

ansible -m win_ping windows -e "ansible_connection=ssh ansible_port=22"
ansible -m ping linux

Launch the main playbook:

 ansible-playbook site.yml
