Deploy endpoint

pip install grpcio
pip install grpcio-tools

Generate the API Descriptors

python3 -m grpc_tools.protoc \
    --include_imports \
    --include_source_info \
    --proto_path=./protos \
    --descriptor_set_out=api_descriptor.pb \
    --python_out=generated_pb2 \
    --grpc_python_out=generated_pb2 \
    ping.proto

Reserve the Gateway

gcloud run deploy api-service \
    --image="gcr.io/cloudrun/hello" \
    --allow-unauthenticated \
    --platform managed \
    --project=demoneil

Update the image in Gateway

chmod +x gcloud_build_image

./gcloud_build_image -s api-service-b3zzuedwgq-uc.a.run.app -c 2022-02-13r0 -p demoneil

gcloud run deploy api-service \
    --image="gcr.io/demoneil/endpoints-runtime-serverless:2.34.0-api-service-b3zzuedwgq-uc.a.run.app-2022-02-13r0" \
    --allow-unauthenticated \
