Ping Pong gRPC

A little ping pong program that talks via gRPC.

Buld and save image

Build the docker container with all necessary binaries

docker build -t grpcpingpong .
docker save grpcpingpong > grpcpingpong.tar

copy the image to the other server and do following command to load it

docker load -i grpcpingpong.tar

Run server

using docker command

docker run -d --name test -p 8090:8090 grpcpingpong server --msg "custom return message" --port 8090

using predefined docker-compose yaml

docker-compose -f docker-compose-sample.yaml up -d

Run client

docker exec -ti clitest ping-pong-grpc client --port 7051

Server mode

You can run ping-pong-grpc in server mode. In this mode it will wait for incoming SendPing() calls and respond with a simple Pong message.

You can run it in server mode like this:

build/ping-pong-grpc server

Client mode

You can also run ping-pong-grpc in client mode. In this mode it will open a connection to a instance running in server mode and send SendPing() calls with a Ping message.

You can run a single ping rpc in client mode like this:

ping-pong-grpc client

Cycle mode

Besides running a single ping rpc call you can also start the client in cycle mode which will run consecutive rpc calls with a sleep duration.

You can run the client in cycle mode like this:

ping-pong-grpc client --cycle-mode --cycle-sleep-duration=1s

Log levels

All modes support multiple log levels via the --log-level flag.
