Ansible Conditional Based on Stdout of Result

Ansible conditional based on stdout of result?

Try checking to see it if equals a blank string or not?

- hosts: myhosts
  tasks:
  - name: echo hello
    command: echo hello
    register: result
  - command: somecommand {{ result.stdout }}
    when: result.stdout != ""
  - command: someothercommand
    when: result.stdout == ""

Why is Ansible not failing this string in stdout conditional?

When you write:

when: '"new_ios_md5" | string in md5_result.stdout'

You are looking for the literal string "new_ios_md5" inside the variable md5_result.stdout. Since you actually want to refer to the new new_ios_md5 variable, you ened to remove the quotes around it:

when: 'new_ios_md5 | string in md5_result.stdout'

Get exactly data from stdout or stdout_lines with exact words of output

- hosts: localhost
  become: true
  gather_facts: false

  vars:
    RESULT:
      STDOUT_LINES:
        - "# name admin@shrrah.esquimail.com"
        - "zimbraIsDelegatedAdminAccount: FALSE"
        - ""
        - "# name prueba5@prueba5.com"
        - ""
        - "# name prueba7@prueba7.com"
        - "zimbraIsDelegatedAdminAccount: TRUE"
        - ""
        - "# name prueba9@prueba9.com"

  tasks:

  - name: Show STDOUT_LINES
    debug:
      msg: "{{ RESULT.STDOUT_LINES }}"

resulting into an output only of

TASK [Show STDOUT_LINES] *****************
ok: [localhost] =>
  msg:
  - '# name admin@shrrah.esquimail.com'
  - 'zimbraIsDelegatedAdminAccount: FALSE'
  - ''
  - '# name prueba5@prueba5.com'
  - ''
  - '# name prueba7@prueba7.com'
  - 'zimbraIsDelegatedAdminAccount: TRUE'
  - ''
  - '# name prueba9@prueba9.com'

and if Ansible Callback plugin is configured to YAML instead of JSON.

To get lines containing certain strings only you may Loop over the list based on a Condition

  - name: Show lines with TRUE only
    debug:
      msg: "{{ item }}"
    when: "'TRUE' in item"
    loop: "{{ RESULT.STDOUT_LINES }}"

resulting into an output of

TASK [Show lines with TRUE only] *******************************
ok: [localhost] => (item=zimbraIsDelegatedAdminAccount: TRUE) =>
  msg: 'zimbraIsDelegatedAdminAccount: TRUE'

Further Documenation

• Index of all Callback Plugins

If you like to have the line before included, you could use an approach like

  - name: Show lines with TRUE and line before
    debug:
      msg: "{{ RESULT.STDOUT_LINES[ansible_loop.index0 - 1] }}\n{{ item }}"
    when: "'TRUE' in item"
    loop: "{{ RESULT.STDOUT_LINES }}"
    loop_control:
      extended: true
      label: "{{ ansible_loop.index0 }}"

resulting into an output of

TASK [Show lines with TRUE and line before] *************************************************************************************************************************************
ok: [localhost] => (item=6) =>
  msg: |-
    # name prueba7@prueba7.com
    zimbraIsDelegatedAdminAccount: TRUE

Further Documentation

• Extended loop variables

Since you are using the shell module, you could use also an approach like

- name: DELEGATED ADMIN ACCOUNTS - check, get and send to the file domain.list
  shell: 
    cmd: /opt/zimbra/bin/zmprov -l gaaa -v zimbraIsDelegatedAdminAccount | grep -B 1 TRUE

and gather only result lines which are true an the line before.

Further Q&A

• grep a file, but show several surrounding lines?

Ansible stdout lines result without brackets and quotes

Short answer

Use stdout instead of stdout_lines and use yaml callback instead of default. Then

    - debug:
        msg: "{{ sys_info.stdout }}"

gives what you want

  msg: |-
    Serial Number: Test12345
    Technician Name: Team
    Custom Serial Number: Test12345
    System Part Number: xxxx
    Rev: A10
    Last Rev: A10
    Paka Number: Auto
    Ip Address: 1.1.1.1

Details

shell> cat info.txt
Serial Number: Test12345
Technician Name: Team
Custom Serial Number: Test12345
System Part Number: xxxx
Rev: A10
Last Rev: A10
Paka Number: Auto
Ip Address: 1.1.1.1

shell> cat test.yml
- hosts: localhost
  tasks:
    - name: Tested unit information
      command: cat info.txt
      register: sys_info
    - debug:
        msg: "{{ sys_info.stdout_lines }}"

What you see depends on the DEFAULT_STDOUT_CALLBACK. The default callback format is JSON

shell> ANSIBLE_STDOUT_CALLBACK=default ansible-playbook test.yml

TASK [debug] ***************************************************************
ok: [localhost] => {
    "msg": [
        "Serial Number: Test12345",
        "Technician Name: Team",
        "Custom Serial Number: Test12345",
        "System Part Number: xxxx",
        "Rev: A10",
        "Last Rev: A10",
        "Paka Number: Auto",
        "Ip Address: 1.1.1.1"
    ]
}

If you want to create plain text from the list use Jinja, e.g.

    - debug:
        msg: |-
          {% for line in sys_info.stdout_lines %}
          {{ line }}
          {% endfor %}

, or simply join the lines

    - debug:
        msg: "{{ sys_info.stdout_lines|join('\n') }}"

Both options give the same result

shell> ANSIBLE_STDOUT_CALLBACK=default ansible-playbook test.yml

TASK [debug] ***************************************************************
ok: [localhost] => {
    "msg": "Serial Number: Test12345\nTechnician Name: Team\nCustom Serial Number: Test12345\nSystem Part Number: xxxx\nRev: A10\nLast Rev: A10\nPaka Number: Auto\nIp Address: 1.1.1.1\n"
}

Use callback yaml to get what you want

shell> ANSIBLE_STDOUT_CALLBACK=yaml ansible-playbook test.yml

TASK [debug] ***************************************************************
ok: [localhost] => 
  msg: |-
    Serial Number: Test12345
    Technician Name: Team
    Custom Serial Number: Test12345
    System Part Number: xxxx
    Rev: A10
    Last Rev: A10
    Paka Number: Auto
    Ip Address: 1.1.1.1
