| - | ====== NUC 2 ====== | ||
| - | This is the second NUC in the [[Stack of NUCs]]. This will be the Ansible controller, the Control Node. We will build it using the USB install and autoconfiguration method we tested with [[NUC 1]]. | ||
| - | Ansible terms: | ||
| - | * Control node - A system on which Ansible is installed. You run Ansible commands such as ansible or ansible-inventory on a control node. | ||
| - | * Managed node - A remote system, or host, that Ansible controls. | ||
| - | * Inventory - A list of managed nodes that are logically organized. You create an inventory on the control node to describe host deployments to Ansible. | ||
