Ansible set_fact with with_items always prints last item

[kumare...@gmail.com]

Hi Experts,

I am looking to capture certain service status using ansible the problem is debug prints only last item.Below is the expected output.

Hostname : test

httpd --> Running

ntpd  --> Running

Below are the playbook.

---

- hosts: test

  become: true

  gather_facts: false

  tasks:

    - name: Service facts

      service_facts:

    - set_fact:

       elk_app1: "{{ ansible_facts.services[item + '.service'].name}} Running"

      when: ansible_facts.services[item + '.service'].state == 'running'

      with_items:

        - httpd

        - ntpd

      register: foo_result

    - debug: msg="{{ foo_result }}"

Regards

Kumar

Hello Kumar,

if you use set_fact with a loop, you need to reference the variable on the right hand side:

set_fact:
elk_app1: "{{ elk_app1 | default('') + ansible_facts.services[item + '.service'].name + ' Running\n' }}"

The default filter is necessary as the variable is undefined on the first iteration of the loop.

Hello Kumar,

use the YAML callback plugin, e.g in ansible.cfg:

# Use the YAML callback plugin.
stdout_callback = yaml

This changes the output to look like as follows:

ok: [buster-test-box] =>
elk_app1: |-
sympa.service Running
wwsympa.service Running
