gRPC Endpoints for Compute Engine with ESP

[Di Lu]

Hi,

I'm following the instructions in https://cloud.google.com/endpoints/docs/grpc/get-started-compute-engine-docker to set up a gRPC endpoint in a compute engine instance.

I did the steps and tried to use the following command to verify the endpoints

python bookstore_client.py --host bookstore.endpoints.stork-product.cloud.goog --port 8080

but I got the following errors:

grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:

status = StatusCode.UNAVAILABLE

details = "DNS resolution failed for service: bookstore.endpoints.stork-product.cloud.goog:8080"

Below are the running dockers in compute engine instance: 

sudo docker ps -a

CONTAINER ID   IMAGE                                               COMMAND                  CREATED          STATUS          PORTS                                                           NAMES

Does anyone know what I missed? and is there any other way to verify the gRPC endpoints?

Any comment is appreciated.

Thanks,

Di

This tutorial does not setup DNS, so you cannot make a call to `bookstore.endpoints.stork-product.cloud.goog`. You need to use the IP address of the GCE instance instead.

python bookstore_client.py --host SERVER_IP --port 80

This should work. If it does, you can then setup DNS for the host using this guide: https://cloud.google.com/endpoints/docs/grpc/cloud-goog-dns-configure
