Yet another Ansible iteration

Is this the code (without formatting) that you're looking for?

shell> cat play.yml

- hosts: localhost
  vars:
    my_list:
      - name: "asd-ASX030-vc-0"
        key_2: ["A", "B"]
      - name: "asd-ASX030-vc-1"
        key_2: ["C", "D"]
  tasks:
    - debug:
        msg: "{{ item.name }} = {{ item.key_2 }}"
      loop: "{{ my_list }}"
shell> ansible-playbook play.yml | grep msg

msg: asd-ASX030-vc-0 = [u'A', u'B']
msg: asd-ASX030-vc-1 = [u'C', u'D']
