Ansible Roles
Learn how to use Ansible roles to automate Apache installation on RHEL with both minimal and advanced configurations, including firewall rules.
Overview
In this lab, you will learn how to structure Ansible playbooks using roles, which allow you to organize tasks into reusable components. You will explore how roles simplify playbook management by separating tasks, handlers, and configurations into structured directories. By leveraging roles, you will enhance the modularity, maintainability, and reusability of your automation scripts.
Learning Outcomes:
-
Understand the concept of Ansible roles and their advantages in structuring playbooks.
-
Learn how to create and organize roles in the Ansible directory structure.
-
Implement automation for installing and managing Apache using Ansible roles.
-
Configure firewalld settings using the ansible.posix collection.
-
Execute playbooks that utilize roles to manage multiple system configurations.
Key Concepts:
-
Ansible Roles: A structured way to organize playbooks by breaking them into reusable components such as tasks, handlers, and variables.
-
Modularity and Reusability: Roles allow you to apply the same configurations across different environments with minimal modifications.
-
Apache Web Server Automation: Automating Apache installation and service management through Ansible.
