Quick gRPC example using C++ and Docker

grpc c++ docker

A simple hello world example of building a gRPC server and client in Docker.

building

Create the docker image

make build

Note: gRPC needs to be sudmoduled and initialized properly

running with docker

First create a network so the containers can talk to each other

make create_network

This creates a bridge network. The containers can now resolve each other by container names. This is why the in the client.cc source file, the server address is grpcserver:5000.

Now run a server and a client container in seperate terminals

make run_server

make run_client

Stop the server container with docker stop grpcserver.

running locally

If you want to run the server and client without Docker, protoc and grpc need to be installed. Find installation instructions for your platform in their docs.

Next, build the server and client. Note that in client.cc you need to change the server address to 0.0.0.0:5000 (line 42).

mkdir build
cd build
cmake ..
make

Now you should be able to run the server and client in seperate terminals:

./server

./client
