I am trying to develop a Ansible Inventory Plugin based on some examples I
found on Github.
This is my Yaml File:
---
plugin: oracle_inventory
oem_db_server: myoem.domain.com
oem_db_port: 1521
oem_db_sid: OEM
oem_schema_owner: SYSMAN
oem_owner_password: password
oem_target_read_user: READ_ONLY_USER
oem_target_read_password: password
And this is my implementation of the Plugin:
from __future__ import (absolute_import, division, print_function)
from loguru import logger
__metaclass__ = type
DOCUMENTATION = r'''
name: oracle_inventory
plugin_type: inventory
short_description: Returns Ansible inventory from Oracle databases
description: Returns Ansible inventory from Oracle databases which are
registered in Oracle Enterprise Manager (OEM)
options:
plugin:
description: Name of the plugin
required: true
choices: ['oracle_inventory']
oem_db_server:
description: The OEM repository database server
required: true
oem_db_port:
description: The Port of the OEM repository database
required: true
oem_db_sid:
description: The ORACLE_SID of the OEM repository database
required: true
oem_schema_owner:
description: The owner of the OEM repository schema
required: true
oem_owner_password:
description: The password of the OEM repository schema owner
required: true
oem_target_read_user:
description: The user which is allowed to query the host,
agent, and database OEM targets and its properties
required: true
oem_target_read_password:
description: The password of the OEM target read user
required: true

self.inventory.add_host(host = "myserver.domain", group=

Both files are located in /home/kai/inventory_plugins
When I execute
ansible-inventory -vvv -i oracle_inventory.yml --list
I get this warnings:

Could anyone help me solving this?
