Question

I received the following data from the setup module:

\"ansible_nodename\": \"3d734bc2a391\",
\"ansible_os_family\": \"RedHat\",
\"ansible_pkg_mgr\": \"yum\",         


        

Answer 1

To get first item of the list:

- debug:
    msg: "First item: {{ ansible_processor[0] }}"

Or:

- debug:
    msg: "First item: {{ ansible_processor | first }}"
