Ansible Modules – How To Use Them Efficiently (Examples)

Ansible modules are distinct units of code with specific functionality that abstract complexity and provide end-users with an easier way to execute automation tasks without needing all the details. They can be executed directly from the command line or used in tasks as their main functional layer. Modules should follow idempotency principles, meaning consecutive runs of the same module should have the same effect if nothing else changes. Handlers can control the flow execution of modules and tasks in a playbook. Custom modules can be developed in any programming language that returns JSON data. Some common Ansible modules include package manager modules (yum & apt), service module, file module, copy module, template module, lineinfile & blockinfile modules, cron module, wait_for module, command & shell modules.
