What are Ansible playbooks and how do they work?

Ansible playbooks are YAML files that define a series of tasks to be executed on remote machines. They allow for automation of configuration management, application deployment, and task execution.

Can you give me an example of a simple playbook?

Sure! Here's a simple playbook that installs Nginx on a remote server:

- hosts: webservers
  tasks:
    - name: Install Nginx
      apt:
        name: nginx
        state: present

How do I run a playbook once it's created?

You can run a playbook using the command ansible-playbook playbook.yml, where playbook.yml is the name of your playbook file.

What are some common modules used in playbooks?

Common modules include apt for package management, copy for transferring files, and service for managing services.
