Ansible Extract JSON Tag - json

Question

I'm trying to work with Infoblox API, and it's responses. I would need to extract values of tags from the response, that seems to be in JSON format, but I cannot find the way to do it.
Here is my playbook:
- name: "Checking _node_exporter Service Record for {{ inventory_hostname }}"
local_action:
module: uri
url: "{{ infobloxapiurl }}record:srv?name=_node_exporter.domain.com&target={{ inventory_hostname }}"
force_basic_auth: yes
user: "{{ infobloxuser }}"
password: "{{ infobloxpassword }}"
validate_certs: no
return_content: yes
register: _infoblox_results
- debug:
var: _infoblox_results.json
The _infoblox_results.json variable looks like this:
TASK [prometheus : debug] *******************************************************************************************************************************************************************************************
task path: /ansible/roles/tasks/task.yml:38
ok: [server.domain.com] => {
"_infoblox_results.json": [
{
"_ref": "record:srv/ZG5zLmJpbmRfc3J2JC5fZGVmYXVsdC5jb20udmNpbnQuZXcxL19ub2RlX2V4cG9ydGVyLzAvMC85MTAwL3Zhcm5pc2g3MDJ0c3QuZXcxLnZjaW50LmNvbQ:_node_exporter.domain.com/default",
"name": "_node_exporter.domain.com",
"port": 9100,
"priority": 0,
"target": "server.domain.com",
"view": "default",
"weight": 0
}
]
}
I want to use the data of _ref from _infoblox_results.json, but I wasn't able to extract it with regex_replace (it drops back the full _infoblox_results.json):
- name: Get Record ID
set_fact:
_rcdid: "{{ _infoblox_results.json | regex_replace('record:srv.*\\/default,', '\\1') }}"
- debug:
var: _rcdid
when: _infoblox_results.json != []
Neither with json_query (it drops back nothing):
- name: Get Record ID
set_fact:
_rcdid: "{{ _infoblox_results.json | json_query('_ref') }}"
- debug:
var: _rcdid
when: _infoblox_results.json != []
Can someone please point me into the right direction?

Answer 1

You have already an object in the memory, so simply refer to its value: _infoblox_results.json[0]._ref contains the string record:srv/ZG5zLmJpbmRfc3J2JC5fZGVmYXVsdC5jb20udmNpbnQuZXcxL19ub2RlX2V4cG9ydGVyLzAvMC85MTAwL3Zhcm5pc2g3MDJ0c3QuZXcxLnZjaW50LmNvbQ:_node_exporter.domain.com/default.
With that you can split the string and select the second element:
- name: Get Record ID
set_fact:
_rcdid: "{{ _infoblox_results.json[0]._ref.split('/')[1] }}"
