Using the "shell" module you can do all the piping you want to get it down
to exactly the list you one, one item per line, and then use
result.stdout_lines as your list. In your example:
- name: Get running services
shell: "getRunningServices {{ inventory_hostname }} |grep :running:
|cut -d: -f4"
register: service_result
- name: List running services
debug: msg="{{ item }} is running"
with_items: service_result.stdout_lines
