GRPC状态代码不可用，详细信息为OS错误

Question

仅在使用docker stack部署启动容器时，才能获得间歇性错误`grpc._channel._rendezvous：＆lt; _ _rendezvous of RPC终止： 状态= statuscode.unavailable 详细信息=" OS错误" debug_error_string = " {"创建"："@1565004909.399609656"， "描述"："从同伴收到的错误"， "文件"：" src/core/lib/surface/call.cc"， " file_line"：1036， " grpc_message"：" OS错误"， " grpc_status"：14}"

channel = implementations.insecure_channel(host, int(port))
stub = prediction_service_pb2.beta_create_PredictionService_stub(channel)
request = predict_pb2.PredictRequest()
result = stub.Predict(request, 100.0)`

Answer 1

在解决方案上正在添加重试逻辑，捕获GRPC错误并再次致电stub.predict

try:
        result = stub.Predict(request, 100.0)  # 100 seconds
    except grpc.RpcError as e:
        result = stub.Predict(request, 100.0)  # 100 seconds
