Resposta vazia do módulo shell do Ansible

  • 772

Quando executo o comando "quem sou eu" usando o módulo shell do ansible, recebo uma resposta vazia, não consigo descobrir por quê?

  hosts: server1
  remote_user: devops
  become: true
  tasks:
    - name: print current user
      shell: who am i
      register: userr
    - debug:
        msg: "{{ userr.stdout }}"

[root@ansible test]# ansible-playbook test.yml 

PLAY [test playbook] ********************************************************************************************************************************

TASK [Gathering Facts] ******************************************************************************************************************************
ok: [server1]

TASK [print current user] ***************************************************************************************************************************
changed: [server1]

TASK [debug] ****************************************************************************************************************************************
ok: [server1] => {
    "msg": ""
}

PLAY RECAP ******************************************************************************************************************************************
server1                    : ok=3    changed=1    unreachable=0    failed=0

    Acho que o motivo é que o ansible não está usando um shell de login para executar o comando. Portanto, o comando não está exibindo nada.

    If you replace: 

who am i

with:

su - anotheruser; who am i

    Você deve ver uma saída.
