nornir ansible

Ansible Inventory plugin for nornir.

Install

In most cases installation via pip is the simplest and best way to install nornir_ansible.

pip install nornir_ansible

Basic Example

In your nornir configuration, set the inventory plugin value to AnsibleInventory

---
inventory:
  plugin: AnsibleInventory
  options:
    hostsfile: "inventory.yaml"

The hostsfile inventory option argument should point to a valid Ansible inventory file, in this case a yaml style inventory such as:

---
all:
  vars:
    ansible_python_interpreter: "/usr/bin/python3"
    username: "vrnetlab"
    password: "VR-netlab9"
  children:
    sea:
      hosts:
        sea-eos-1:
          ansible_host: "172.18.0.14"
        sea-nxos-1:
          ansible_host: "172.18.0.12"
      children:
        arista-eos:
          hosts:
            sea-eos-1:
          vars:
            platform: "eos"
        cisco-nxos:
          hosts:
            sea-nxos-1:
          vars:
            platform: "nxos"

Initialize your nornir object and validate the appropriate inventory plugin was loaded, and the inventory file was parsed:

>>> from nornir import InitNornir
>>> nr = InitNornir(config_file="config.yaml")
>>> print(nr.config.inventory.plugin)
<class 'nornir_ansible.plugins.inventory.ansible.AnsibleInventory'>
>>> print(nr.inventory.hosts)
{'sea-eos-1': Host: sea-eos-1, 'sea-nxos-1': Host: sea-nxos-1}
>>>
