Ansible Tower (”Ansible Tower”) is a software product provided as part of an annual Red Hat Ansible Automation Platform subscription entered into between you and Red Hat, Inc. (”Red Hat”).

Ansible is an open source software project and is licensed under the GNU General Public License version 3, as detailed in the Ansible source code:

Starting with Ansible Tower 3.8, you must have valid subscriptions attached before installing the Ansible Automation Platform. See Attaching Subscriptions for detail.

2.4. Node Counting in Licenses

For more information on managed node requirements for licensing, please see

2.5. Attaching Subscriptions

Starting with Tower 3.8, you must have valid subscriptions attached before installing the Ansible Automation Platform. Attaching an Ansible Automation Platform subscription enables Automation Hub repositories. A valid subscription needs to be attached to the Automation Hub node only. Other nodes do not need to have a valid subscription/pool attached, even if the [automationhub] group is blank, given this is done at the repos_el role level and that this role is run on both [tower] and [automationhub] hosts.


Attaching subscriptions is unnecessary if your Red Hat account enabled Simple Content Access Mode. But you still need to register to RHSM or Satellite before installing the Ansible Automation Platform.

To find out the pool_id of your Ansible Automation Platform subscription:

#subscription-manager list --available --all | grep "Ansible Automation Platform" -B 3 -A 6

The command returns the following:

Subscription Name: Red Hat Ansible Automation Platform, Premium (5000 Managed Nodes)
Provides: Red Hat Ansible Engine
Red Hat Single Sign-On
Red Hat Ansible Automation Platform
SKU: MCT3695
Contract: ********
Pool ID: ********************
Provides Management: No
Available: 4999
Suggested: 1

To attach this subscription:

#subscription-manager attach --pool=<pool_id>

If this is properly done, and all nodes have Red Hat Ansible Automation Platform attached, then it will find the Automation Hub repositories correctly.

To check whether the subscription was successfully attached:

#subscription-manager list --consumed

To remove this subscription:

#subscription-manager remove --pool=<pool_id>
