HPE-grpc

HPE Career Preview Program Repository for gRPC configuration for VASA/vVols

Files

• grpc/server.cpp -> The main grpc server file
• grpc/client.cpp -> The main grpc client file
• grpc/service.proto -> The proto file for grpc
• grpc/CMakeLists.txt -> CMake file for building the application

Installation and Running Steps

It is made to run only on Linux systems, so make sure to have a Linux VM or Linux OS on your system.

Run the following commands

Clone the repo

git clone https://github.com/Amoghk04/HPE-grpc.git

Make sure you have downloaded the protobuf and grpc modules beforehand, else run the below commands

sudo apt update
sudo apt install -y cmake g++ autoconf libtool pkg-config
git clone --recurse-submodules -b v1.70.1 https://github.com/grpc/grpc
cd grpc
mkdir -p cmake/build
cd cmake/build
cmake -DgRPC_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=/usr/local ../..
make -j$(nproc)
sudo make install

After the modules are installed, confirm you have the latest version of protobuf

protoc --version

It must be 3.21.12(at the time of writing this readme file), if it is not then run the commands

sudo apt update
sudo apt install -y protobuf-compiler libprotobuf-dev libgrpc++-dev

Now build the proto file by going inside the grpc directory and typing the command

protoc --proto_path=. --cpp_out=. --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` service.proto

This generates service.pb.h and service.pb.cc (Protobuf messages) service.grpc.pb.h and service.grpc.pb.cc (gRPC stubs)

Now create a build directory inside /grpc and create the CMake files

mkdir build
cd build
cmake ..

After the build is finished, run the below command

make -j$(nproc)

Now your server and client are ready to talk via gRPC, start by opening 2 terminals inside the /gRPC/build directory and running

./server 

and

./client
