How to validate the results for with_items?

[Ramu]

Hi All,

 I want to implement a logic for below requirement

block:

   - name: A task

     shell: grep '{{ item }} is present ' /in/a/file

     register: output

     with_items: "{{ host_group }}"

always:

   - set_fact:

       failed_items:  <All the items for which the result is failed>

      

However, the output is a list. And each item in the list would contain rc, whose value could be true or false based on the item in the group. 

Is there a way to find the items for which the task is failed and construct a final result string.

Thanks in advance,

Ramu

Just use the jinja2 filters that operate on lists:

failed_items: '{{ output.results|selectattr('failed', 'equalto', True)list }}'

You probably want a pipe before "list" and after the parens.

Thanks Brian and Todd. 

But the list will still have all other attributes. I just want to know the items for which the test is failed.

Thanks and regards,

Ramu

Just add the map filter

{{ output.results|selectattr('failed', 'equalto', True) | map(attribute='item') | list }}
