Using Docker to build and deploy a C++ gRPC service

This sample demonstrates how to create a basic gRPC service in C++ and build it it using GCC and CMake in a Docker container. It also shows how to create a Docker image that contains only the service implementation, without the tools needed to build it. It is based on the Dockerfile used to build the official gRPC CXX image.

Build and run the sample

git clone https://github.com/npclaudiu/grpc-cpp-docker.git
cd grpc-cpp-docker
docker build -t calculator .
docker run --rm -it calculator

To run the shell instead of starting the server hosting the calculator service you can use:

docker run --rm -it --entrypoint=bash calculator

First build will take some time, as it also clones, builds and installs protobuf and grpc. You should end up with a Docker image tagged calculator, based on Debian and containing the release build of the calculator service and all of its dependencies, all under /opt/calculator. There is also an intermediary build image, where the project is actually built. Please see the Dockerfile and the documentation for Docker multi-stage builds for more.
