Ansible

Red Hat's agentless, open-source automation tool that configures systems and network devices using YAML playbooks over SSH, WinRM, or APIs.

Definition

Ansible runs from a control node against hosts in an inventory, executing idempotent modules. It needs Python on Linux targets but not on network devices, which use connection plugins such as network_cli, netconf, and httpapi.

Example

ansible-playbook -i inventory.yml site.yml --limit core_switches

Exam tip

Ansible is agentless and push-based; playbooks are YAML and templates are Jinja2.
