Learn ANSIBLE with Real Code Examples

Controller - central system where playbooks run

Managed nodes - target servers/devices (agentless)

Inventory - static or dynamic host lists

Modules - perform tasks on nodes

Plugins - extend functionality (connection, callback, filter, etc.)

Playbook -> Controller executes tasks -> Modules run on nodes -> Changes applied idempotently
