grpc-golang-workshop

In this workshop, you will learn using Golang or Python how to build a gRPC server, a gRPC client and how to deploy a gRPC server using docker.

Based on the official gRPC workshop - https://codelabs.developers.google.com/codelabs/cloud-grpc/index.html - Where I extended to include deploying gRPC server using docker and learn to implement a gRPC client/gRPC server using Golang and Python.
