Globbing with Lookup

[Navid Paya]

Hi all

Not sure if this is even the right tile. So I have a set of SSH keys, I want to be used as authorized keys for users. I've put all of them in a directory and am trying to do the job but nothing happens. So I did some debugging. This is what I do when not using a variable:

- name: Some debugging

  debug: msg="{{ lookup('file', 'public_ssh_keys/navid.pub') }}"

And it returns what I expect. Now I try doing a loop:

- name: Some debugging

  debug: msg="{{ lookup('file', 'public_ssh_keys/{{ item }}.pub') }}"

  with_items:

    - navid

But this time it returns this:

TASK: [base-ami | Some debugging] *********************************************

ok: [default] => (item=navid) => {

    "item": "navid",

    "msg": ""

}

So how am I supposed to have it return what I expect? I think it's probably a matter of using the single and double quotes right but how?

Regards

Navid

mustaches don't stack!

you want:
"{{ lookup('file', 'public_ssh_keys/' + item + '.pub') }}"

Stupid me. Thanks, Brian. That worked like a charm.

Hi Navid,

I 'm trying something similar, based on: http://blather.michaelwlucas.com/archives/1819

Do you mind share your approach?

Thanks,

Here's how I did it. Created a directory with the public keys in it. For instance:

base-ami/files/public_ssh_keys/jack.pub

base-ami/files/public_ssh_keys/jill.pub

- name: Create basic users

  user: name={{ item }} shell=/bin/bash groups=grabtaxi

  with_items:

    - jack

    - jill

And then used lookup to populate the keys:

- name: Use the public keys from the users for the their login

  authorized_key:  user={{ item }} key="{{ lookup('file', 'public_ssh_keys/' + item + '.pub') }}"

  with_items:

    - jack

    - jill

You could make it fancier using vars and all but I think you get the gist of it.
