Is it possible to create uploguser with mongodb_user

[litewhatever]

Hello

When looking into library/mongodb_user_fixed.py I found the following:

- mongodb_user:
    login_user: root
    login_password: root_password
    database: admin
    user: oplog_reader
    password: oplog_reader_password
    state: present
    replica_set: belcher
    roles:
      - db: local
        role: read

But when trying to use it as follows:

mongodb_users:
  - {
    name: oploguser,
    password: passw0rd,
    database: admin,
    roles: 
      - db: local
        role: read
}

Ansible gives YAML syntax error.

PLAY [apply common configuration to all nodes] *********************************************************************************************************************************************************************************************************************************
ERROR! Syntax Error while loading YAML.
  did not find expected node content

The error appears to have been in '/etc/ansible/group_vars/mongodb': line 40, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

    roles:
      - db: local
      ^ here

Please advise if it is currently possible to create a oplog user in admin database with read access into local database.

You have a mix of syntax here:

it should be

roles: [{db: 'local', role: 'read'}]
