Variable to be selected from the options

[Veera]

Hi,

I have the below variable defined  in my playbook.

reboot_option:

- IfRequired

- Never

 - Always

while calling the same  variable from the playbook ,   the value "IfRequired'  must be the default.

 "rebootSetting": "{{ reboot_option | default(Ifrequired) }}" 

While executing the playbook without extra-vars reboot_option then by "ifrequired " need to the default,.

If the playbook is executed with -e "reboot_option=Never" or "Always"  then it should select the given option.

how to call the dictionary items with default as "Ifrequired"? 

Or I have to declare  the variables in a different way ?

Using ansible's order of precedence you can set the default value in the playbook and override it with extra_vars.

override.yaml:

---

- name: test overriding playbook variable

  hosts: all

  become: false

  gather_facts: false

  vars:

    rebootSetting: "ifRequired"

  tasks:

    - name: reboot setting

      debug: var=rebootSetting

Execution: note the first test does not provide an extra_var value for rebootSetting, while the second and third do provide one.

% ansible-playbook -i localhost, override.yaml 

PLAY [test overriding playbook variable] *******************************************************************************

TASK [reboot setting] **************************************************************************************************

ok: [localhost] => {

    "rebootSetting": "ifRequired"

}

PLAY RECAP *************************************************************************************************************

localhost                  : ok=1    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0   

% ansible-playbook -i localhost, override.yaml -e rebootSetting=Never

PLAY [test overriding playbook variable] *******************************************************************************

    "rebootSetting": "Never"

}

% ansible-playbook -i localhost, override.yaml -e rebootSetting=Always

PLAY [test overriding playbook variable] *******************************************************************************

TASK [reboot setting] **************************************************************************************************

ok: [localhost] => {

    "rebootSetting": "Always"

}

PLAY RECAP *************************************************************************************************************

localhost                  : ok=1    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0
