What components and structures do you use when writing Ansible playbooks?

The following components and constructs are typically used when writing Ansible playbooks:

• Tasks — individual actions performed on hosts.
• Modules — built-in or third-party tools for executing specific operations (e.g., copy, yum, service).
• Variables — for storing data that can be used within the playbook.
• Handlers — tasks that are executed when notified, usually for restarting services.
• Conditions (when) — allow tasks to be executed only if certain conditions are met.
• Loops — for repeating tasks over a list of items.
• Roles — structured sets of tasks, files, and variables for reuse.

Example of a simple task with a condition and a loop:

- name: Install packages
  yum:
    name: "{{ item }}"
    state: present
  loop:
    - httpd
    - git
