Make mongo output pure JSON friendly by disabling all fields with custom types (like _id) in query.
Then use from_json Ansible filter to parse output.
- hosts: localhost
vars:
qry: "db.repo.findOne({ $and: [{'product': 'Admin'}, {'env':'SHK'}] },{_id:false})"
tasks:
- name: Get data
command: mongo Advantage --quiet --eval "{{qry}}"
register: temp
- name: Save parsed data
set_fact:
mongo_result: "{{ temp.stdout | from_json }}"
- name: Print some data
debug:
var: mongo_result.appName
