Hello gRPC

Simple server and client examples showcasing gRPC features(including proxy and propagate, running in containers and kubernetes) with:

:coffee: What is

🍎 :apple: done 🍏 :green_apple: unimplemented 🥑 :avocado: known issues

:coffee: How to use

1 Envs

• GRPC_SERVER: grpc server host on client side.
• GRPC_SERVER_PORT: grpc server port on client side.
• GRPC_HELLO_BACKEND: next grpc server host on server side.
• GRPC_HELLO_BACKEND_PORT:next grpc server port on server side.
• GRPC_HELLO_SECURE: set it as Y when you want to use TLS on both sides.

Running in containers sample:

client(kotlin) -[tls]:8881-> server1(java) -[tls]:8882-> server2(golang) -[tls]:8883-> server3(rust)
