\e[0m comapre this string in failed_when condition

[Kunalsing Thakur]

Hello Team,

When i was checking for string comparison in failed_when condition.

the ansible task does not give any output if search is not found. but it will print stdout variable as   stdout: "\e[0m"

But when i try to compare my ansible playbook gives error.

I tried two ways in codition:-

1) failed_when: "'{{\e[0m}}' in pulp.results.[0].stdout"

Error which i got:-

or is there way we can compare empty string.

Gentle reminder, is anyone can help on this

You would need to convert that value from a shell escape sequence, to a python escape sequence, for consumption by PyYAML.

The easiest way to express this will likely be:

- name: searching the rpm into pulp repo

  shell: pulp-admin rpm repo content rpm --repo-id=mobi-snapshots --match 'filename={{ item }}'

  with_items: "{{ rpmname | default([]) }}"

  register: pulp

  when: rpmsearch is defined

  failed_when: escape in pulp.results.[0].stdout

  vars:

    escape: "\u001b[0m"

Hello Matt,

 i tried with task

- name: searching the rpm into {{ reponame }} repo
  shell: pulp-admin rpm repo content rpm --repo-id={{reponame}} --match 'filename={{ item }}'

  with_items: "{{ rpmname | default([]) }}"
  register: pulp

  when: search is defined

  failed_when: escape in pulp.results.[0].stdout
  vars:
   escape: "\u001b[0m"

But get jinja templating error as below:-

TASK [mobi_ansible_role_pulp : searching the rpm into infra] ******************************
task path: /etc/ansible/roles/mobi_ansible_role_pulp/tasks/pulp.yaml:5
Saturday 06 April 2019  09:55:41 +0000 (0:00:02.011)       0:00:02.434 ********

  msg: 'The conditional check ''escape in pulp.results.[0].stdout'' failed. The error was: template error while templating string: expected name or number. String: {% if escape in pulp.results.[0].stdout %} True {% else %} False {% endif %}'

I tried use following syntax also:-

- name: searching the rpm into {{ reponame }} repo
  shell: pulp-admin rpm repo content rpm --repo-id={{reponame}} --match 'filename={{ item }}'

  with_items: "{{ rpmname | default([]) }}"
  register: pulp

  when: search is defined

  failed_when: 'escape in pulp.results.[0].stdout'
  vars:
   escape: "\u001b[0m"

Any Help will be much appreciated..

Hello Matt,

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:-
