Feature Summary

Hi Team,

The ingress today supported in awx-operator only allows http-based backend (except for when type is route). As most of the ingress controllers support https backend, the ingress manifests should also support it to route the traffic over https to the backend awx service.

Example service:

apiVersion: v1
kind: Service
metadata:
  name: '{{ ansible_operator_meta.name }}-service'
  namespace: '{{ ansible_operator_meta.namespace }}'
spec:
  selector:
    app.kubernetes.io/name: '{{ ansible_operator_meta.name }}-web'
    app.kubernetes.io/managed-by: '{{ deployment_type }}-operator'
    app.kubernetes.io/component: '{{ deployment_type }}'
  ports:
  - protocol: TCP
    port: 443
    targetPort: 8053

Ingress definition:
cat << EOF | kubectl apply -f -

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: website-ingress
  annotations:
    kubernetes.io/ingress.class: azure/application-gateway
    appgw.ingress.kubernetes.io/ssl-redirect: "true"
    appgw.ingress.kubernetes.io/backend-protocol: "https"
    appgw.ingress.kubernetes.io/backend-hostname: "backend"
    appgw.ingress.kubernetes.io/appgw-trusted-root-certificate: "backend-tls"
spec:
  tls:
    - secretName: frontend-tls
      hosts:
        - awx.com
  rules:
    - host: awx.com
      http:
        paths:
        - path: /
          backend:
            service:
              name: '{{ ansible_operator_meta.name }}-service'
              port:
                number: 443
          pathType: Exact
EOF

Currently its not possible to turn on https backend without setting ingress_type = route.
