How to Inject Host and Group Vars from Ansible into NetBox Config Templates

Ansible and NetBox Tip:
Pass Ansible group_vars and host_vars into NetBox Config Templates by sending your Ansible vars, making them available directly within your Config Templates.

Here is an example:

# Ansible Playbook
- name: Trigger NetBox to return rendered configuration
  ansible.builtin.uri:
    url: "{{ NETBOX_ENDPOINT }}/api/dcim/devices/{{ device_id }}/render-config/"
    method: POST
    headers:
      Authorization: "Token {{ NETBOX_TOKEN }}"
      Content-Type: "application/json"
      Accept: "text/plain"
    body:
      format: txt
      local_context_data: "{{ vars }}"  # <---- Send Ansible vars to NetBox
    body_format: json
    return_content: yes
    status_code: 200
  delegate_to: localhost
  register: response
  tags:
    - build

# Jinja Template Usage (NetBox Config Template)
{% for dns_server in local_context_data.dns_servers %}
ip name-server {{ dns_server }}
{% endfor %}
