Clean up debug output

[Thomas Stephen Lee]

Hi,

I have a small Ansible playbook.

-----------------%<-----------------

- hosts: localhost

  tasks:

    - name: Populate service facts

      ansible.builtin.service_facts:

    - name: Print service facts

      loop:

      - postfix

      - rsyslog

      - sshd

      ansible.builtin.debug:

        var: ansible_facts.services['{{ item }}.service']['state']

-----------------%<-----------------

The output is

-----------------%<-----------------

PLAY [localhost] ***************************************************************

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

ok: [localhost]

TASK [Populate service facts] **************************************************

ok: [localhost]

TASK [Print service facts] *****************************************************

ok: [localhost] => (item=postfix) => {

    "ansible_facts.services['postfix.service']['state']": "running",

    "ansible_loop_var": "item",

    "item": "postfix"

}

ok: [localhost] => (item=rsyslog) => {

    "ansible_facts.services['rsyslog.service']['state']": "running",

    "ansible_loop_var": "item",

    "item": "rsyslog"

}

ok: [localhost] => (item=sshd) => {

    "ansible_facts.services['sshd.service']['state']": "running",

    "ansible_loop_var": "item",

    "item": "sshd"

}

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

localhost                  : ok=3    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0  

-----------------%<-----------------

What I want is

TASK [Print service facts]

should print only 

"ansible_facts.services['rsyslog.service']['state']": "running"

The other three should be hidden.

Any easy trick for this ?

Thanks

Try

- name: Print service facts

ansible.builtin.debug:
msg: '{{ _sr }}: {{ _st }}'

loop:
- postfix
- rsyslog
- sshd

vars:
_sr: 'ansible_facts.services["{{ item }}.service"]["state"]'
_st: '{{ ansible_facts.services[item ~ ".service"].state }}'

The single/double quotes of the results are reversed. If this is a
problem you'll have to escape them.

ok: [localhost] => (item=sshd) =>

msg: 'ansible_facts.services["sshd.service"]["state"]: active'
