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.
