Protobuf over gRPC

A simple integration between protobuf and gRPC written in Golang.

Building

$ make clean
$ make all

Starting gRPC and REST servers

$ docker-compose up --build -d

Testing

$ curl -X POST -d '{"message":"ping"}' 'http://go-grpc:8081/v1/ingest'

Swagger docs

$ curl -X GET 'http://go-grpc:8081/swagger/ingestwg.swagger.json'

and you should get a response like the following:
