🗒️ Configuration

The Ludus range configuration file is a yaml document that describes the virtual machines and optionally the network rules, router settings, and defaults a user would like to deploy.

An example file is described below:

Range Config Schema

range-config.yml
ludus:
  - vm_name: "{{ range_id }}-ad-dc-win2019-server-x64" # The name of the VM in Proxmox. You can use the `{{ range_id }}` template string which resolves to your range ID (i.e. JS)
    hostname: "{{ range_id }}-DC01-2019"   # The hostname for the VM. Note: Windows host names are limited to 15 characters due to NETBIOS
    template: win2019-server-x64-template  # The template that will be the base for this VM (`ludus templates list` to get a list of them)
    vlan: 10            # The VLAN for this VM. This number will be the third octet of the VM's IP and must be 2<=vlan<=255
    ip_last_octet: 11   # The last octet for this VM's IP address. Must be unique in the VLAN.
    ram_gb: 8           # The amount of RAM for this VM
    cpus: 4             # The number of cpu cores to allocate to this VM (can provision more CPUs than the host physically has)
    windows:            # This key must be set for windows VMs - all subkeys are optional

      - customgroup2

      - '*.example.com'     # rewrites responses for all example.com subdomains but *not* example.com
    unmanaged: false        # Set this to true for VMs that cannot report an IP to ansible via proxmox (no qemu-guest-agent, i.e. EDR appliances). You *must* manually configure this VM to have the IP defined in the config or risk leaking data during testing. Default: false
