How to register a system with Red Hat Subscription-Manager with Ansible?
I’m going to show you a live Playbook and some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.
Ansible register a system with Red Hat Subscription-Manager
- community.general.redhat_subscription
- Manage registration and subscriptions to RHSM using the subscription-manager command
Today we’re talking about the Ansible module redhat_subscription.
The full name is community.general.redhat_subscription, which means that is part of the collection community.general maintained by the Ansible community
Manage registration and subscriptions to RHSM using the subscription-manager command.
This module is specific for RedHat Enterprise Linux.
Parameters
- state string - present/absent
- username string - access.redhat.com or Satellite 6 username
- password string - access.redhat.com or Satellite 6 password
- auto_attach boolean - no/yes auto-consume available subscriptions
- pool_id list - subscription pool IDs to consume
- pool string - ‘^(Red Hat Enterprise Server|Red Hat Virtualization)$’
- consumer_id string - resume a previous registration
Let me summarize the main parameters.
The state parameter allows you to specify if you want to add or remove a registration from the target machine.
The username and password allow you to specify the access.redhat.com website credential or Satellite 6 credential.
Once the machine is registered you need to define which subscription to consume.
The auto_attach allows you to auto consume all the available subscriptions for the Machine.
Alternatively you can specify manually the ID in the pool_id list or a text with all the products that you want to add.
Another interesting option is the parameter customer_id to resume a previous registration.
