Is it possible to consume an external gRPC service? I have been unable to get it to work. when I attempt to call the external service, I receive an
rpc error: code = Unavailable desc = upstream connect error or disconnect/reset before headers on my go client. Isito proxy also similarly reports a
200 UF status/response flag.
I tried registering the external service with a ServiceEntry like so:
apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: name: grpc-service spec: hosts: - external.grpc.service.io ports: - name: grpc number: 7777 protocol: GRPC location: MESH_EXTERNAL resolution: DNS
I appreciate any help in setting this up. Thanks.
