Your First Ansible Playbook

Playbooks are where Ansible becomes useful in practice. They describe what should happen on a group of hosts in a readable YAML format.

Example Playbook

---
- name: Install Apache on webservers
  hosts: webservers
  become: yes
  tasks:
    - name: Ensure Apache is installed
      apt:
        name: apache2
        state: present
      when: ansible_os_family == "Debian"

Run the Playbook

ansible-playbook -i hosts.ini playbook.yml

What This Playbook Does

• Targets the webservers group
• Uses privilege escalation with become
• Installs Apache on Debian-based systems

Practical Advice

• Start with one small, testable task
• Use meaningful task names
• Run with --check before applying changes when possible
