register: pulp
when: rpmsearch is defined
- debug:
var: pulp.results.stdout

Hello Kunalsing,

please try pulp.stdout instead.

You are using register with a loop. That means pulp.results is a list
and there's an element for each item in that list.

You can access the stdout for the first item with pulp.results.0.stdout

This should be
var: pulp.stdout

Hi sebastian,
when i try to fail the task with this below condition i get the error in task

failed_when: pulp.results.0.stdout == “\e[0m”

TASK [mobi_ansible_role_pulp : searching the rpm into pulp repo] *************************************************
task path: /etc/ansible/roles/mobi_ansible_role_pulp/tasks/pulp.yaml:4

when i print the pulp.results.0.stdout it will give me following output:-
TASK [mobi_ansible_role_pulp : debug] ****************************************************************************

ok: [inplp01p2.infra.smf1.mobitv] =>
pulp.results.0.stdout: “\e[0m”

which is blank so i want to failed this task?

Hi sebastian,
when i try to fail the task with this below condition i get the error in
task

*failed_when: pulp.results.0.stdout == "\e[0m"*

TASK [mobi_ansible_role_pulp : searching the rpm into pulp repo]

  msg: 'The conditional check ''pulp.results.0.stdout == "\e[0m"'' failed.
The error was: error while evaluating conditional (pulp.results.0.stdout ==
"\e[0m"): ''dict object'' has no attribute ''results'''

While you are in the loop you should be able to use just pulp.stdout,
only afterwards the results are merged.

Hi sebastian,

pulp.results.0.stdout give me output “\e[0m”

But when I try to access in failed_when condition
It is giving me below error.
fatal: [node]: FAILED! =>

msg: ‘The conditional check ‘‘pulp.results.0.stdout == “\e[0m”’’ failed. The error was: error while evaluating conditional (pulp.results.0.stdout == “\e[0m”): ‘‘dict object’’ has no attribute ‘‘results’’’

Looks like in faiked_when condition it needs dictionary?

I was able to successfully do this task by following the instructions.
Thanks for matt to give some logic.

  • name: searching the rpm into {{ reponame }} repo
    shell: pulp-admin rpm repo content rpm --repo-id={{reponame}} --match ‘filename={{ item }}’
    loop: “{{ rpmname | default() }}”
    register: pulp
    when: search is defined
    failed_when: pulp.stdout == “\u001b[0m”

Result:-

This issue is resolved now. :slight_smile:

Hi,

Instead of stdout, I would suggest using stdout_lines. For multiline output this is much nicer, e.g.

- hosts: all
  tasks:
    - name: Run ls.sh and output "ls /"
      script: ls.sh
      register: out

    - debug: var=out.stdout_lines

gives

TASK: [debug var=out.stdout_lines] ******************************************** 
ok: [local] => {
    "var": {
        "out.stdout_lines": [
            "total 61", 
            "lrwxrwxrwx   1 root root     7 Feb 15  2015 bin -> usr/bin", 
            "drwxr-xr-x   6 root root  1024 Aug 24 22:08 boot", 
            "drwxr-xr-x  22 root root  3580 Sep  8 18:41 dev",  
            [...] 
            "drwxr-xr-x   9 root root  4096 Aug 25 19:14 usr", 
            "drwxr-xr-x  13 root root  4096 Feb 25  2015 var"
        ]
    }
}

Regarding real-time output for debugging purposes, there is a closed bug reporthttps://github.com/ansible/ansible/issues/3887#issuecomment-54672569 discussing the reasons why this is not possible and will not be implemented.
