module: rhsm_repository
short_description: Manage RHSM repositories using the subscription-manager command
description:
- Manage (Enable/Disable) RHSM repositories to the Red Hat Subscription
Management entitlement platform using the C(subscription-manager) command.
author: Giovanni Sciortino (@giovannisciortino)
notes:
- In order to manage RHSM repositories the system must be already registered
to RHSM manually or using the Ansible C(redhat_subscription) module.
- It is possible to interact with C(subscription-manager) only as root,
so root permissions are required to successfully run this module.
