2.1.1. Ansible Playbook Support

For customers with a paid Enterprise: Standard or Enterprise: Premium Ansible Tower Subscription, Red Hat offers Ansible Playbook support [1]. Playbook support consists of support for:

  • Runtime execution problems for Playbooks run via Tower
  • Assistance with Playbook errors and tracebacks
  • Limited best practice guidance in Ansible use from the Ansible Experts

Playbook support does not consist of:

  • Enhancements and fixes for Ansible modules and the Ansible engine
  • Assistance with the creation of Playbooks from anew
  • Long-term maintenance of a specific Ansible or Ansible Tower version


[1]Playbook support is available for customers using the current or previous minor release of Ansible. For example, if the current version of Ansible is 2.2, Red Hat provides Ansible Playbook support for versions 2.2 and 2.1. In the event an Ansible Playbook workaround is not available, and an Ansible software correction is required, a version update will be required.

2.2. Trial / Evaluation

While a license is required for Ansible Tower to run, there is no fee for managing up to 10 hosts. Additionally, trial licenses are available for exploring Ansible Tower with a larger number of hosts.

2.3. Subscription Types

Ansible Tower is provided at various levels of support and number of machines as an annual Subscription.

All Subscription levels include regular updates and releases of Ansible Tower.

2.4. Node Counting in Licenses

The Tower license defines the number of Managed Nodes that can be managed by Ansible Tower. A typical license will say ‘License Count: 500’, which sets the maximum number of Managed Nodes at 500.

Ansible Tower counts Managed Nodes by the number of hosts in inventory. If more Managed Nodes are in the Ansible Tower inventory than are supported by the license, you will be unable to start any Jobs in Ansible Tower. If a dynamic inventory sync causes Ansible Tower to exceed the Managed Node count specified in the license, the dynamic inventory sync will fail.

If you have multiple hosts in inventory that have the same name, such as “webserver1”, they will be counted for licensing purposes as a single node. Note that this differs from the ‘Hosts’ count in Tower’s dashboard, which counts hosts in separate inventories separately.
