Stdout error

Hi,

I’m getting the below error. I’ve tried: service_status.stdout == ‘enabled’,
and service.status.stdout.find(‘enabled’) != -1 but no luck.

TASK [set_fact] *********************************************************************************************
fatal: [localhost]: FAILED! => {“msg”: "The conditional check ‘service_status.results[0].stdout == ‘enabled’’ failed. The error was: error while evaluating conditional (service_status.results[0].stdout == ‘enabled’): ‘dict object’ has no attribute ‘results’\n\nThe error appears

The error says “results” don’t exist.

I think that line should be:
when: ‘enabled’ in service_status.stdout_lines[0]

Hi,

I’ve tried that and - service_status.stdout_lines[0] == ‘enabled’
but still same error.

Can you copy the error message ? I don’t see how the error can include something related to “results” is that is no longer part of the “when” entry.

Try to write the full value of “service_status” right after being used to register the command with this:

  • debug
    msg: “{{ service_status }}”

to detect what is missing. That dictionary should include stdout, stderr and stdout_lines keys if command “systemctl is-enabled rsyslog” was executed with no errors.

fatal: [localhost]: FAILED! => {“changed”: true, “cmd”: “systemctl is-enabled rsyslog”, “delta”: “0:00:00.005366”, “end”: “2020-12-18 11:37:39.206468”, “msg”: “non-zero return code”, “rc”: 1, “start”: “2020-12-18 11:37:39.201102”, “stderr”: “”, “stderr_lines”: , “stdout”: “disabled”, “stdout_lines”: [“disabled”]}

Ok, it seems the command “systemctl is-enabled ” returns rc=0 if server is enabled and rc=1 if service is not enabled.

Any rc != 0 is usually considered as an error.

You can add the following:

  • name: check that log service is enabled if it’s installed
    shell: systemctl is-enabled rsyslog
    register: service_status

failed_when: service_status.rc != 0 and service_status.rc != 1

(more conservative approach)

or

  • name: check that log service is enabled if it’s installed
    shell: systemctl is-enabled rsyslog
    register: service_status

ignore_errors: yes

(this will ignore any error. Use with caution.)

I added your recommended codes, and received no error.
However, the rescue block didn’t execute.
