AWX cannot access its own REST API (Name or service not known)

I am running awx-operator on a k3 cluster. I have a role, update_host_group, that tries to use the AWX REST API to manipulate Ansible groups.

---
- name: Update Ansible Tower inventory
  uri:
    url: https://awx.example.com/api/v2/groups/36/hosts
    user: "{{ admin_username }}"
    password: "{{ admin_password }}"
    method: 'POST'
    body: '{ "name" : "{{ update_ati_fqdn }}" }'
    force_basic_auth: yes
    status_code: 201
    body_format: json
    validate_certs: no

I created an inventory named "AWX Meta Inventory" which has just one host, localhost. I also created a job template: "Run Update Host Group Playbook" that executes a playbook that uses the role, update_host_group. When I launch this template I get this error:

TASK [update_host_group : Update Ansible Tower inventory] **********************
fatal: [localhost]: FAILED! => {"changed": false, "elapsed": 0, "msg": "Status code was
 -1 and not [201]: Request failed: <urlopen error [Errno -2] Name or service not known>", 
"redirected": false, "status": -1, "url": "https://awx.example.com"}

Note: Obvisouly don't actually use example.com. I use my real domain name.

UPDATE: I have tried adding hostAliases to my kubernetes but I am not well versed in k* admin. I looked at the docs here: https://kubernetes.io/docs/tasks/network/customize-hosts-file-for-pods/

But of course that doesn't tell where in the awx deployment to add the hostAliases stanza. So I am just guessing and breaking things. Does anyone know where I need to put my hostAliases?

This is more sort of a workaround. I am sure there is probably a better solution. I read the documentation here: https://docs.ansible.com/automation-controller/latest/html/administration/containers_instance_groups.html#customize-the-pod-spec

Then I:

• Logged into my AWX Web UI
• Navigated to Administration > Instance Groups
• clicked on the pencil icon to edit the default instance group
• clicked the Customize pod specification radio button
• and then added these lines just above the containers: line:

hostAliases:
  - hostnames:
    - awx.example.com
    ip: 10.0.3.52

then click the apply button and my task worked (had to update the status_code to look for status code 204).
