Write a playbook

Create a playbook that pings your hosts and prints a "Hello world" message.

About this task

Ansible uses the YAML syntax. YAML is a human-readable language that enables you to create playbooks without having to learn a complicated coding language.

Procedure

  1. Create a file named playbook.yaml in your ansible_quickstart directory, with the following content: 
    - name: My first play
  hosts: myhosts
  tasks:
    - name: Ping my hosts
    ansible.builtin.ping:

    - name: Print message
    ansible.builtin.debug:
      msg: Hello world
  2. Run your playbook: 
    $ ansible-playbook -i inventory.ini playbook.yaml

Results

Ansible returns the following output:
