how to call knative service [grpc server] by using a python client

I have created a knative service[gRPC server] in aks cluster, I have exposed the service using istio gateway private static IP,

After using the command kubectl get ksvc I have got an address sample-app.test.10.153.157.156.sslio.io

When I try to use this address in the python client, it throws error saying failed to connect addresses, but if I try to hit the service using curl sample-app.test.10.153.157.156.sslio.io I am able to hit the service, I don't know what i am missing here.. please suggest..

Solution

  • GRPC uses HTTP/2. You may need to explicitly name your port h2c. I'm assuming that you've tested the container locally without Knative in the path and have been able to make a grpc call in that case.
