problems with add_host

[Glyn Davies]

Hi Guys,

I am having some issues getting add_host to create a dynamic inventory correctly.

Here is the relevant section from my playbook:

tasks:
    - name: Connect to Cloud
      # assume RC file has already been sourced
      os_auth:

    - name: launch web instances
      os_server:
        name=web0{{ item }}
        flavor={{ flavor }}
        image={{ image }}
        key_name={{ key_name }}
        state=present
        wait=true
        network={{ network }}
        security_groups={{ security_groups }}
        auto_ip=true
      register: newnodes
      with_sequence:
        count={{ count }}

    # - debug:
    #     var: newnodes

    - name: add nodes to runtime inventory
      add_host:
        name={{ item.name }}
        # group=workers
        # ansible_host={{ item.public_v4 }}
      with_items:
        - "{{ newnodes.results.server }}"


The tasks 'Connect to Cloud' and 'launch web servers' work fine.

I also ran debug on the newnodes variable and it is returning the correct data. The problem is that when I try to run the 'add nodes to runtime inventory' task I get the following:

[DEPRECATION WARNING]: Skipping task due to undefined Error, in the future this will be a fatal error.. This feature will be removed in a future release. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.

If I run the playbook with -vvvv I get no further information. I have also tried various combinations of the variable name 'newnodes.results.server' in the with_items section but no joy.

Anyone able to see what I have missed here?

Cheers,
Glyn

That isn't how you invoke a dynamic inventory... 

There's an example of how an openstack dynamic inventory script is used on in the Ansible.com docs: http://docs.ansible.com/ansible/intro_dynamic_inventory.html#other-inventory-scripts

An ansible dynamic inventory script returns valid JSON that defines hosts, groups, etc. -- and if it wants to return all the info for all nodes at once, it can set per-host values in a _meta group.7

Hi Uditha,

Yes I realise that is an option but what I am trying to do is use the in-memory inventory  see http://docs.ansible.com/ansible/add_host_module.html

This way I can have the same running playbook perform subsequent tasks on the new hosts once they are online.
