I am am using ansible to add admin user in mongodb.. I used below playbook but i am getting error. Can someone suggest the solution.. i have also installed pymongo prior to adding user in order to use module. authentication is disabled in mongod.conf and bindIp is set to 0.0.0.0

mongoNoAuth: "/usr/bin/mongosh 'mongodb://localhost:27017/admin' --norc --quiet"

I create the users manually:
I assume you have a wrong configuration setting on the host.
This doesn’t look like an Ansible error to me.
To help you further out, you should disable mongo authentication, and restart mongo. Then, create 3 users,
admin,rootanduserAdminAnyDatabase. Then restart mongo. Here is an Ansible role I’ve written for MongoDB, so you can take a look there to see how it works.
