GO GRPC solution

Build and run without docker

Make sure you have install protoc and protoc go generator and run make command inside root directory. It will create all necessary files, build up server and client application and copy them to the root directory. After this you can start ./server and after this ./client. Server application will listen for incoming data from client, process data and send it back to the client. Client will do calculations, print the results and stop. Server will remain running and wait for another incoming data.

Build and run with docker

Build docker image

Make sure your pwd is root folder of repository and run build

docker build -t grpc-go-app .

Run docker image and start server

Start docker image.

docker run -it -p 50005:50005 grpc-go-app

Start client

Show list of containers where you should see grpc-go-app running.

docker ps

If docker is running you can start ./client directly in root folder or enter container and run it there.

Copy grpc-go-app container id and replace [container-id]

docker exec -it [container-id] bash

This command will exec bash in the container. To start client and process the data start ./client

./client

Testing

Tests are checking in Makefile, and for manual testing run go test ./... in root directory.
