'name' is a required argument.

I have the following tasks:

  • name: Add new instance to host group
    add_host: hostname={{ item.public_ip }} groupname=launched
    with_items: ec2.results[0].instances

  • name: set inventory_hostname var
    add_host: inventory_hostname={{ item.public_dns_name }} groupname=launched
    with_items: ec2.results[0].instances

The first one works correctly but i’m getting the following error in the second one:

‘name’ is a required argument.

Play results below:

Thanks for your help

The add_host module requires ‘name’ as a parameter, or aliases of ‘hostname’ or ‘host’. It doesn’t accept ‘inventory_hostname’. See http://docs.ansible.com/ansible/add_host_module.htm
