This project is to showcase how to deploy multiple grpc service with kubernetes and rely on kube's internal dns to make them visible to each other

To run

1. make sure you have a running kubernetes cluster (minikube will work, see here for details on how to run minikube).

2. run server as pod/service in kube cluster

   $ cd server && kubectl apply -f server.yaml
   

3. run client as pod/service in kube cluster

   $ cd client && kubectl apply -f client.yaml
   

4. verify the client & server are working by

   $ kubectl get pods
   $ kubectl logs -f <client-pod-name-from-output-above>
   $ (in another terminal) kubectl logs -f <server-pod-name-from-output-above>
   

   you should see client prints out response from server every few seconds you should also observe server prints received message every few seconds

5 (TODO) test load balancing with grpc
