  service:
    name: "{{ item }}"
    state: reloaded
  with_items: "{{ (servicename is defined) | ternary((servicename|default('')).split(','),[]) }}"

- name: checking the service status {{ansible_hostname}}
  service:
    name: "{{ item }}"
    state: started
  with_items: "{{ (servicename is defined) | ternary((servicename|default('')).split(','),[]) }}"

```

```YAML
playbook.yaml
- name: checking service is skipped by default
  hosts: {{host}}
  vars_files:
    - /etc/ansible/inventories/group_vars/common.yaml
  serial: 1
  roles:
