inventory = hosts

Create a hosts file as hosts in the project directory

[webservers]
 ansnode1 ansible_ssh_host=192.168.56.202 ansible_python_interpreter=/usr/bin/python
 ansnode2 ansible_ssh_host=192.168.56.203 ansible_python_interpreter=/usr/bin/python

[webservers:vars]
 ansible_port=22
 http_port=8080

[dbservers]
 ansnode3 ansible_ssh_host=192.168.56.204 ansible_python_interpreter=/usr/bin/python
 ansnode4 ansible_ssh_host=192.168.56.205 ansible_python_interpreter=/usr/bin/python

Create a file named called as motd_playbook.yml in your project directory

---
 # YAML documents begin with the document separator ---
 # The minus in YAML this indicates a list item. The Playbook contains a list
 # of plays, with each play being a dictionary

- name: 'Basic play loop using with with_items'

  # Target: where our play will run and options it will run with
  hosts: all

  # Task: the list of tasks that will be executed within the playbook
  tasks:
    - name: Configuring a MOTD (message of the day)
     copy:
       content: "Welcome to {{ item }} Linux - Ansible Rocks !!\n"
       dest: /etc/motd
    notify: MOTD changed
    with_items: ['OracleLinux','Ubuntu']
    when: ansible_distribution == item

  # Handlers: handlers that are executed as a notify key from a task
  handlers:
    - name: MOTD changed
      debug:
        msg: The MOTD was changed

# Three dots indicate the end of a YAML document
