问题
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

回答1:
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

While I could see the requests in the nginx access log when using requests library or pynetbox api: https://pastebin.com/LyLw7svm, the same was not true when using the Ansible modules.
xx.xx.xx.xx - - [08/Jul/2020:06:43:03 +0000] "GET / HTTP/1.1" 200 4342 "-" "python-requests/2.23.0"
xx.xx.xx.xx - - [08/Jul/2020:06:45:00 +0000] "GET /api/ HTTP/1.1" 200 403 "-" "python-requests/2.23.0"

Also tried to test it with Netbox Ansible Collections as documented [1]
$ cat ansible.cfg
[defaults]
inventory = ./inventory
collections_paths = ./collections
$ cat inventory
NETBOX ansible_host=xx.xx.xx.xx ansible_ssh_user=user
[netbox]
NETBOX
$ cat group_vars/all.yml
---
netbox_url: https://netbox.url
netbox_token: XXX
$ cat collections/requirements.yml
collections:
- name: netbox.netbox
source: https://galaxy.ansible.com
$ ansible-galaxy collection install -r collections/requirements.yml
Process install dependency map

Yet, the task fails with Failed to establish connection to Netbox API

Am I missing something?
