Loop in a loop

[Acrobis Nubian]

Hi all,

If someone could help me on the following:

I am trying to automate as maximum as possible the addition of authorized keys to my new remote servers by doing the below playbook, but I am getting the following error:

===============================================================

fatal: [web]: FAILED! => {"failed": true, "msg": "'list object' has no attribute 'name'"}

fatal: [db]: FAILED! => {"failed": true, "msg": "'list object' has no attribute 'name'"}

===============================================================

I've tried playing with the list of variables, tried also new loop with_item after the with_file, still no good luck, could someone please tell me how can I achieve my goal by having authorized_key module going to each file without specifying each time the full address like public_keys/web/authorized_key

- hosts: all

  vars:

    pcs:

      - name: web

      - name: db

  tasks:

  - name: Set up authorized_keys for the deploy user

    authorized_key: user=root key="{{ item }}"

    with_file:

      - public_keys/{{ pcs.name }}/authorized_key

Something like this should work:

- name: Set up authorized_keys for the deploy user

authorized_key: user=root key="{{ lookup('file', 'public_keys/{{
item.name }}/authorized_key') }}"
with_items: pcs

Thanks Kai! That's another way of looking at the problem :) Much appreciated!

But also I'm still curious, if I'd need to do a loop in a loop like I intended in the previous example, is it possible to do that in Ansible?

Kind regards,

Acrobis

To do a loop in a loop in Ansible, you need to put the inner loop in a
yaml file, and the use - include: with a loop and loop_control.
You can see an example here:
