I am dockering our current application and deploying on kubernetes cluster. We have 2 services, namely, service-A and service-B. One of our services(example service-A) uses websocket. we have configured a rule in ingress to route the websocket request directly to service-A on port 8080. Also have a rule to route other requests to service-B on port 443. But ingress controller always route the websocket request to service-B instead of routing to service-A.
So, I removed the service-B rule from ingress, but still its routed as tls request and request never reaches service-A. Not sure why its rerouted as TLS instead of http request upgraded to websocket connection.
Please find my ingress configuration below:
apiVersion: extensions/v1beta1
kind: Ingress

field.cattle.io/publicEndpoints: '[{"addresses":[""],"port":443,"protocol":"HTTPS","serviceName":"cluster42:service-B","ingressName":"cluster42:my-ingress","hostname":"cluster42-phase-0 ","path":"/","allNodes":false},{"addresses":[""],"port":443,"protocol":"HTTPS","serviceName":"cluster42:service-A","ingressName":"cluster42:my-ingress","hostname":"cluster42-phase-0 ","path":"/ws-service","allNodes":false}]'

I expect the request to be routed to service-A instead of service-B. Can you please let me know if I am missing something in my configuration or doing anything wrong.
Thanks in Advance.
