GRPC sample

GRPC TEST

This is a sample that shows a bit about grpc and docker swarm. The demo contains two kind of services. A GRPC server that works as a counter and a HTTP server which use the counter service to keep track of the number of times the endpoint /count has been hit

Requirements (OSX)

Go lang

This example is written in Go

$ brew install go

Glide

Go package manager

$ brew install glide

GRPC

$ brew install protobuf
$ go get -u github.com/golang/protobuf/{proto,protoc-gen-go}

Docker

You have to configure docker in swarm mode

$ docker swarm init

Usage

To start the demo run:

$ make

This will run one replica of the server and three replicas of the client. To see some action run this:

$ while true;  do curl "http://localhost:8080/count"; sleep 0.5; done

and in a separate terminal run:

$ make log

To stop the services run:

$ make stop
