Hi,

I have playbook to retrieve the Instance id of Openstack nodes.Now everything works fine but the resgitered value for instid.stdout_lines gets an undefined error.
The error was: ‘dict object’ has no attribute ‘stdout_lines’ … but when i debug the complete registered variable instid i see stdout_lines. but why its failing when i debug it using instid.stdout_lines

What is the complete output from a debug of instid?

Regards, K.

When using register with with_items/loop you'll have instid.results which is a list where each item contain the output for each command.

When you get errors like this always run a
  - debug: var=instid

There are 11 items , i will paste the out put of one item, all others are similar, or this mail will be lengthy. SO pasting the out put of one item.

Hi Kai,

I had already tried it it gives me o/p as same as :
debug:
msg: {{ instid }}

Both the o/ps are similar.

Now i want the stdout_lines for each item as my desired o/p
something like:
e8ebc5a4-17f3-4b80-a935-03164211a804 TOMICS2
7865dvgsf-17f3-4b80-a935-03164211a804 TOMICS1
abc12345g-17f3-4b80-a935-03164211a804 TOMIAS2

As I wrote instid contains a results which is a list so you need to loop over it to get the individual results.

- debug: msg="{{ item.stdout }}"
  with_items: "{{ instid.results }}"

Post the complete output of

  • debug:
    var: instid

Posting snippets is useless.

Hi Kai,

I could do achieve what i intended. I made the following changes using Jinja format and my issue solved.
Thanks for the help. Th echanges i made was:
In the Instance id section i used the foloing formula and it worked like a charm.

  • name: Set fact for Instance id from Tenant ID
    delegate_to: localhost
    set_fact:
    id_list: “{% for item in instid.results %}
    {{ item.stdout_lines[0].split()[0] }}
    {% endfor %}”

  • name: Set fact for Desired Instance ids
    set_fact:
    desired_instid: “{{ id_list.split() }}”
