Summary

  • Automation is a key technique to mitigate human error and quickly ensure that your network is in a consistent, correct state.

  • Ansible is a desired-state engine. It approaches the problem of how to automate technology deployments by expressing them in terms of the required end state of your systems.

  • The Ansible architecture consists of two types of machines: control nodes and managed nodes.

  • Ansible is agentless. Managed nodes do not need any special agent software.

  • Red Hat Ansible Automation Platform is a supported distribution of Ansible that includes Ansible Core, selected Ansible Content Collections, automation content navigator, automation execution environments, automation controller, automation hub, private automation hub, and access to hosted services.

  • A playbook is a text file that contains a list of one or more plays to run in order.

  • Automation content navigator (ansible-navigator) is used to run Ansible Playbooks in an automation execution environment provided by a Linux container image.
