Ansible: Is a Cisco switch a member of a stack?

Today my task was to find out if a given switch is a member of a stack or not.

Starting with manual testing, in order to find out if it’s a stack, i used the command: show switch detail. If there is more than one member, it’s a stack.
In Ansible, I registered the show switch detail command and then parsed it with Genie using the clay584 Ansible plugin.
Finally, I used an assert task to find out how many elements (IDs) are under the stack.
Easy peasy japanese.

- name: show virtual chassis detail
      block:
        - name: run show switch detail
          ios_command:
            commands: show switch detail
          register: show_sw_detail

 

        - name: set fact show switch detail
          set_fact:
            switch_detail_data: "{{show_sw_detail['stdout'][0] | clay584.genie.parse_genie(command='show switch detail', os='ios') }}"
 
    - name: assert that there is more than one member in the stack
      assert:
       that:
         (switch_detail_data["switch"]["stack"]|length > 1)
