        Examples

        # Example that prints the loopback address and gateway for each host
        - debug:
            msg: "System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}"
        
        - debug:
            msg: "System {{ inventory_hostname }} has gateway {{ ansible_default_ipv4.gateway }}"
          when: ansible_default_ipv4.gateway is defined
        
        - shell: /usr/bin/uptime
          register: result
        
        - debug:
