Ansible - Register variable in not defined

[James Gibson]

I am trying to figure out why my variable is not defined and have not been able to find any solutions online.

Can anyone help?

test.yml

---

- name: Test playbook

  hosts: localhost

  connection: local

  vars: 

      test: hello

  tasks:

     - name: test var

       debug:

           msg: "{{ test}}"

       register: test_out

       debug:

           var: test_out

output from playbook:

PLAY [Test playbook] ***********************************************************************************************************************************************************************************

TASK [Gathering Facts] *********************************************************************************************************************************************************************************

ok: [localhost]

TASK [test var] ****************************************************************************************************************************************************************************************

ok: [localhost] => {

    "test_out": "VARIABLE IS NOT DEFINED!"

}

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

localhost                  : ok=2    changed=0    unreachable=0    failed=0

Try this it worked for me, A play takes a list of tasks so each tasks should start with dash `-`:

- name: Test playbook

  hosts: localhost

  connection: local

  vars:

      test: hello

  tasks:

     - name: test var

       debug:

           msg: "{{ test }}"

       register: test_out

     - debug:

           var: test_out

Thanks Syed. I added a validation step and that is failing. 

Updated playbook

-----------------------------------

---

  2 - name: Test playbook

  3   hosts: localhost

  4   connection: local

  5   vars:

  6       test: hello

  7

  8   tasks:

  9      - name: test var

 10        debug:

 11            msg: "{{ test }}"

 12        register: test_out

 13

 14      - debug:

 15            var: test_out

 16

 17      - name: verify var

 18        assert:

 19          that:

 20            - "'{{ test_out.test }}' == hello'"

Output:

        to retry, use: --limit @/home/ox/test.retry

 "test_out": {

        "changed": false,

        "failed": false,

        "msg": "hello"

    }

there is no key named test here. You need to use 'test_out.msg' above.

Yes that worked, but for the client I am working with, I am unable to change the validation. How would I define it so that test_out.test would work?

[Kai Stian Olstad]

You can't since debug doesn't return test.
