No, you don't. Because AWX notification is using like mail client, for example like outlook that connect to mail server.
Do you have access to the Internet on the host with AWX?
I use MicroK8S for AWX deployment
And do this command for checking internet access in pods:
linux@awx:~$ kubectl get pods -n awx
NAME READY STATUS RESTARTS AGE
awx-operator-controller-manager-5d9949568d-lhhxv 2/2 Running 9 (25m ago) 172d
awx-postgres-0 1/1 Running 4 (25m ago) 172d
awx-77b6cccc9d-gbmvk 4/4 Running 15 (25m ago) 172d
Then:
linux@awx:~$ kubectl exec -n awx -i -t awx-77b6cccc9d-gbmvk --container awx-web -- /bin/bash
bash-5.1$
Then:
And it return me internet page. Pod awx-web has internet access!
