Loops

Updated Jan 08, 2021 ·

Overview

This lab practices Ansible loops to repeat tasks over lists of values.

Task 1

The playbook currently runs an echo command to print a fruit name. Apply a loop directive (with_items) to the task to print all fruits defined in the fruits variable.

Task 2

To a more realistic use case. We are attempting to install multiple packages using yum module.The current playbook installs only a single package.
