External Property Enhancement

The following enhancement is applicable only for the helm chart. By setting the authorizationServiceTokenEndPoint property to the authorization service name (Kubernetes service), you cannot use the Authorize button in the Swagger UI for Offer and Price Engine services, as the browser, tries to call the auth Kubernetes service but it is not reachable from the outside of the cluster. To resolve this issue, a new property (authorizationServiceTokenSwaggerEndPoint) has been added to set the authorization service hostname from ingress. Similarly one more property (configuratorServiceExternalUrl) is added to set the Configurator service hostname from ingress.
