echo-sidecar

This directory contains a command-line tool that includes a server and clients for a sample gRPC service that demonstrates all four streaming modes of gRPC.

The server and clients can communicate over TCP ports or Linux abstract sockets.

To use TCP ports, start the server with the --port flag:

echo-sidecar serve --port 8088

Call the client with the --address flag as below:

echo-sidecar call get --address localhost:8088

To use Linux abstract sockets, run the server with the --socket flag:

echo-sidecar serve --socket @echo

Call the client with the --address flag as below:

echo-sidecar call get --address unix:@echo

Running echo-sidecar call lists the four test methods:

$ echo-sidecar call
Usage:
  echo-sidecar call [command]

Available Commands:
  collect
  expand
  get
  update

Flags:
  -h, --help   help for call

Use "echo-sidecar call [command] --help" for more information about a command.

Running go test in this directory tests the server and clients for all four modes over both a local TCP connection and a Linux abstract socket.
