Hello everybody,
I am learning ansible through its official documentation and videos on youtube, but sadly I can’t get it working with its lookup-mongodb module as described at http://docs.ansible.com/ansible/latest/playbooks_lookups.html#mongodb-lookup
I am using Ubuntu 16.04 based distro (Elementary OS Loki), Python 2.7.12, ansible 2.4.1.0 (installed from ppa:ansible/ansible) and I have also python-pymongo version 3.2-1build1 installed.
When I try to run the example taught in the official documentation (see link above), I got the following error:
app@store:~/ansible_tutorial$ ansible-playbook playbook.yml -vvv
ansible-playbook 2.4.1.0
config file = /home/app/ansible_tutorial/ansible.cfg
configured module search path = [u’/home/app/.ansible/plugins/modules’, u’/usr/share/ansible/plugins/modules’]

As far as I can understand, those bold lines are telling me what is going wrong, the connection to the database.
I’ve searched everywhere I could on internet and watched many ansible videos on youtube but I couldn’t find how I can fix it, it must be something very simple.
From the MongoDB side:
I installed it in the same machine, it is running, and it has the local database and startup_log collection, as you may find below:
app@store:~/ansible_tutorial$ mongo
MongoDB shell version: 3.2.17
connecting to: test
Server has startup warnings:

Does anyone have an idea on how I can get it working?
Many thanks,
