Ansible Modules for VIRL^2/CML^2

Installation

via pip

  pip install ansible-virl

via ansible-galaxy

  ansible-galaxy install 'git@github.com:CiscoDevNet/ansible-virl.git'

Environmental Variables

• VIRL_USERNAME: Username for the VIRL user (used when host not specified)
• VIRL_PASSWORD: Password for the VIRL user (used when password not specified)
• VIRL_HOST: The VIRL host (used when host not specified)
• VIRL_LAB: The name of the lab

Inventory

To use the dynamic inventory plugin, the environmental variabiles must be set and a file (e.g. virl.yml) placed in the inventory specifying the plugin information:

plugin: virl

The dynamic inventory script will then return information about the nodes in the lab:

ok: [hq-host1] => {
    "virl_facts": {
        "config": "#cloud-config\npassword: admin\nchpasswd: { expire: False }\nssh_pwauth: True\nhostname: hq-host1\nruncmd:\n - sudo ip address add 10.0.1.10/24 dev enp0s2\n - sudo ip link set dev enp0s2 up\n - sudo ip route add default via 10.0.1.1\n",
        "cpus": null,
        "data_volume": null,
        "image_definition": "ubuntu-18-04",
        "interfaces": [
            {
                "ipv4_addresses": [],
                "ipv6_addresses": [],
                "mac_address": "52:54:00:13:1b:fb",
                "name": "enp0s2",
                "state": "STARTED"
            }
        ],
        "node_definition": "ubuntu",
        "ram": null,
        "state": "BOOTED"
    }
}
