grpc-zookeeper-lb

This is a toy example of using Zookeeper for load balancing with gRPC. To run:

1. Compile HelloWorldClient and HelloWorldServer.

git clone https://github.com/makdharma/grpc-zookeeper-lb

cd grpc-zookeeper-lb/examples; ./gradelw installDist

2. Download zookeeper stock docker image and start zookeeper.

docker pull zookeeper

docker run -p 2181:2181 --restart always -d zookeeper

3. Start couple of servers

./build/install/examples/bin/hello-world-server 50000 zk://localhost:2181

./build/install/examples/bin/hello-world-server 50001 zk://localhost:2181

4. Run hello-world-client. It should alternate between two servers.

./build/install/examples/bin/hello-world-client zk://localhost:2181
