GRPC Server
The grpc server is a micro.Server compatible server.
Overview
The server makes use of the google.golang.org/grpc framework for the underlying server but continues to use micro handler signatures and protoc-gen-micro generated code.
Usage
Specify the server to your micro service
import (
        "github.com/micro/go-micro"
        "github.com/micro/go-plugins/server/grpc"
)
func main() {
        service := micro.NewService(
                // This needs to be first as it replaces the underlying server
                // which causes any configuration set before it
                // to be discarded
                micro.Server(grpc.NewServer()),
                micro.Name("greeter"),
        )
}
NOTE: Setting the gRPC server and/or client causes the underlying the server/client to be replaced which causes any previous configuration set on that server/client to be discarded. It is therefore recommended to set gRPC server/client before any other configuration
