This project demonstrates a distributed system using gRPC, Kubernetes, and Go. It includes a simple gRPC service, a client, and deployment to Kubernetes for scalability.

• Go (Golang) - Statically typed, compiled programming language.
• gRPC - High-performance Remote Procedure Call (RPC) framework.
• Protocol Buffers (Protobuf) - Efficient data serialization format.
• Docker - Containerization for microservices.
• Kubernetes - Container orchestration platform.

Ensure you have the following installed:

• Go (≥1.20) - Download Go
• Docker - Download Docker
• Kubernetes (Minikube, Kind, or a cloud provider)
• protoc (Protocol Buffers compiler) - Install protoc

git clone https://github.com/RohanCyberOps/grpc-k8s-go-project.git
cd grpc-k8s-go-project

protoc --go_out=. --go-grpc_out=. proto/helloworld.proto

go run server/server.go

go run client/client.go

docker build -t greeter-server:latest -f Dockerfile .

docker run -p 50051:50051 greeter-server

minikube start

kubectl apply -f k8s/deployment.yaml
kubectl apply -f k8s/service.yaml

kubectl get svc greeter-service

Modify client.go to use EXTERNAL-IP:50051, then run:

go run client/client.go

kubectl scale deployment greeter-server --replicas=5

kubectl logs -l app=greeter-server --tail=50 -f
