This should be pretty simple. Use the k8s_facts module for this purpose. Have a look at the docs to get more details about this module.

- name: list of all pods from namespace
      k8s_facts:
        api_key: "{{ k8s_auth_results.k8s_auth.api_key }}"
        kind: Pod
      register: pod-list

Here is a more complete answer for anyone Googling - this deletes all pods in the metallb-system namespace. We need to use json_query ( jq ) to extract the pod names

- name: Get the pods in the metallb-system namespace
  k8s_info:
    kind: Pod
    namespace: metallb-system
  register: pod_list

- name: Print pod names
  debug:
    msg: "pod_list: {{ pod_list | json_query('resources[*].metadata.name')  }} "

- name:  Delete pods
  k8s:
    state: absent
    api_version: v1
    kind: Pod
    namespace: metallb-system
    name: "{{ item }}"
  loop: "{{ pod_list | json_query('resources[*].metadata.name') }}"
