Inventory

inventories/production.yml

web:
  hosts:
    managed_node_01:
      ansible_user: ansible
      ansible_password: 123

The above inventory has a single group called web that has a single managed node called managed_node_01 and the connection details.

Playbook

playbook.yml

- name: My first play
  hosts:
    - web
  tasks:
   - name: Print message
     ansible.builtin.debug:
       msg: Hello world

The above playbook has a single play that runs a single task on the managed nodes from group web.

Running

cd hello-world
ansible-playbook \
-i inventories/production.yml \
playbook.yaml

returns
