Hello World gRPC

This repository contains a simple example of a client-server application using gRPC in Go (golang). The application demonstrates how to exchange personalized greetings and messages between a client and a server.

Prerequisites

Before running the code in this repository, make sure you have the following prerequisites installed:

• Go (golang): You can download and install Go from the official website: https://golang.org/dl/
• Protocol Buffers (Protobuf): You can download and install from the official GitHub repository: protobuf/protobuf
• gRPC Go packages: You can install them using the following command:

   go install google.golang.org/protobuf/cmd/protoc-gen-go
   go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

How to Run

1. Clone this repository to your local machine:

   git clone https://github.com/sigsegv1989/hello-world-grpc.git

2. Navigate to the repository directory:

   cd hello-world-grpc

3. Build the client, server binary and docker images:

   make docker-build

4. Start the server:

   make docker-run-server

5. Run the client:

   make docker-run-client

6. You should see the interaction between the client and server, exchanging personalized greetings and messages.

Project Structure

• api/hello.proto: Protocol Buffers (.proto) file defining the message and service.
• server/server.go: Server implementation that receives and responds to gRPC requests.
• client/client.go: Client implementation that sends gRPC requests to the server.
• certs/: TLS/SSL certificates to enable the mutual authentication between gRPC client and server.
