Troubles with conditions, register and loop

Hi guys,

I’m trying to create a lab file to restart a service only if it’s running.
I have troubles when using variables, register and loop together.

  • name: Restart a service only if it’s active.
    hosts: LAB
    vars:
    sysservices:
  • serviceName: httpd
  • serviceName: smb
    tasks:
  • name: Checking if service is running
    command: /usr/bin/systemctl is-active “{{ item.serviceName }}”
    register: _result
    ignore_errors: yes
    loop: “{{ sysservices }}”
  • name: Restarting services services
    service:
    name: “{{ item.serviceName }}”
    state: restarted
    when: item.rc == 0 ## I tried: item.rc == 0 , item.stdout == “active”, _result.rc == 0, _result.stdout == “active”. All of them didn’t work
    loop: “{{ sysservices }}”

- debug:

msg: “Valor de result {{ _result }}”

Your "Restarting services services¨ task should be looping over the registered _results array, not {{ sysservices }}. Your sysservices has no “rc”. _result should have a list, one item per loop of the registering task. It’s that list you want to process.
