Using Netbox Ansible Modules - ansible

Question

I've been wanting to try out Ansible modules available for Netbox [1].
However, I find myself stuck right in the beginning.
Here's what I've tried:
Add prefix/VLAN to netbox [2]:
cat setup-vlans.yml
---
- hosts: netbox
tasks:
- name: Create prefix 192.168.10.0/24 in Netbox
netbox_prefix:
netbox_token: "{{ netbox_token }}"
netbox_url: "{{ netbox_url }}"
data:
prefix: 192.168.10.0/24
state: present
That gives me the following error:
ansible-playbook setup-vlans.yml
PLAY [netbox] *********************************************************************************************************************************
TASK [Gathering Facts] ************************************************************************************************************************
ok: [NETBOX]
TASK [Create prefix 192.168.10.0/24 in Netbox] ************************************************************************************************
fatal: [NETBOX]: FAILED! => {"changed": false, "msg": "Failed to establish connection to Netbox API"}
PLAY RECAP ************************************************************************************************************************************
NETBOX : ok=1 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
Can someone please point me where I am going wrong?
Note: The NetBox URL is an https://url setup with nginx and netbox-docker [3].
Thanks & Regards,
Sana

Answer 1

I had the same. Apparently the pynetbox api has changed in instantiation (ssl_verify is now replaced by requests session parameters).
I had to force ansible galaxy to update to the latest netbox module with:
ansible-galaxy collection install netbox.netbox -f
The force option did the trick for me.

All playbooks using API modules like netbox (but this is the same for gcp or aws) must use as host not the target but the host that will execute the playbook to call the API. Most of the time this is localhost, but that can be also a dedicated node like a bastion.
You can see in the example on the documentation you linked that it uses hosts: localhost.
Hence I think your playbook should be
---
- hosts: localhost
connection: local
gather_facts: False
tasks:
- name: Create prefix 192.168.10.0/24 in Netbox
netbox_prefix:
netbox_token: "{{ netbox_token }}"
netbox_url: "{{ netbox_url }}"
data:
prefix: 192.168.10.0/24
state: present
