Let's say you have a YAML file named group.yml that contains the following markup. In this example, a group named "my-group" will be created.

apiVersion: user.openshift.io/v1
kind: Group
metadata:
  name: my-group
users:
- jone.doe
- jane.doe

Here is how you can create the group using kubernetes.core.k8s.

---
- hosts: localhost
  module_defaults:
    community.okd.okd:
      host: https://api.op.example.com:6443
      validate_certs: False
  tasks:
  - block:
    - name: login
      community.okd.openshift_auth:
        username: john.doe
        password: itsasecret
      register: openshift_auth_results

    - name: apply group.yml
      kubernetes.core.k8s:
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
        state: present
        src: /path/to/group.yml

    always:

    - name: logout
      community.okd.openshift_auth:
        state: absent
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
...

Instead of using a YAML file you can define the YAML structure in the kubernetes.core.k8s task.

- name: apply group.yml
  kubernetes.core.k8s:
    api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
    state: present
    definition:
      apiVersion: user.openshift.io/v1
      kind: Group
      metadata:
        name: my-group
      users:
      - jone.doe
      - jane.doe

Here is how you can create the group using community.okd.k8s.

---
- hosts: localhost
  module_defaults:
    community.okd.okd:
      host: https://api.op.example.com:6443
      validate_certs: False
  tasks:
  - block:
    - name: login
      community.okd.openshift_auth:
        username: john.doe
        password: itsasecret
      register: openshift_auth_results

    - name: apply group.yml
      community.okd.k8s:
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
        state: present
        definition: "{{ lookup('template', '/path/to/group.yml') | from_yaml }}"

    always:

    - name: logout
      community.okd.openshift_auth:
        state: absent
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
...
