To build Docker image - run command docker build . -t techdozo/grpc-lb-client:1.0.0 from grpc-client-svc To push Docker image - docker push techdozo/grpc-lb-client:1.0.0

gRPC Server

To build Docker image - run command docker build . -t techdozo/grpc-lb-server:1.0.0 from grpc-server-svc To push Docker image - docker push techdozo/grpc-lb-server:1.0.0
