Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. |

Playbooks are automation blueprints, in YAML format, that Ansible uses to deploy and configure nodes in an inventory. ansible.yaml facts.yaml |

- Plays
- The Play contains variables, roles and an ordered lists of tasks and can be run repeatedly.
- Roles
- A limited distribution of reusable ansible content (tasks, handlers, variables, plugins, templates and files) for use inside of a Play.
- Tasks
- The definition of an ‘action’ to be applied to the managed host. Tasks must always be contained in a Play, directly or indirectly (Role, or imported/included task list file).
- Handlers
- Special form of a Task, that only execute when notified by a previous task which resulted in a ‘changed’ status.
 |
Modules (also referred to as “task plugins” or “library plugins”) are discrete units of code that can be used from the command line or in a playbook task. Ansible executes each module, usually on the remote managed node, and collects return values. |
|---|
Plugins are pieces of code that augment Ansible’s core functionality. Ansible uses a plugin architecture to enable a rich, flexible and expandable feature set.
Collections are a distribution format for Ansible content that can include playbooks, roles, modules, and plugins.
