☕ 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.

2 Containers

Running in containers sample:

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

# server3(golang):8883
docker run --rm --name grpc_server_go -d \
 -p 8883:8883 \
 -e GRPC_SERVER_PORT=8883 \
 feuyeux/grpc_server_rust:1.0.0

# server2(rust):8882
docker run --rm --name grpc_server_rust -d \
 -p 8882:8882 \
 -e GRPC_SERVER_PORT=8882 \
 -e GRPC_HELLO_BACKEND=$(ipconfig getifaddr en0) \
 -e GRPC_HELLO_BACKEND_PORT=8883 \
 feuyeux/grpc_server_go:1.0.0

# server1(java):8881
docker run --rm --name grpc_server_java -d \
 -p 8881:8881 \
 -e GRPC_SERVER_PORT=8881 \
 -e GRPC_HELLO_BACKEND=$(ipconfig getifaddr en0) \
 -e GRPC_HELLO_BACKEND_PORT=8882 \
 feuyeux/grpc_server_java:1.0.0

# client(kotlin)
docker run --rm --name grpc_client_kotlin \
 -e GRPC_SERVER=$(ipconfig getifaddr en0) \
 -e GRPC_SERVER_PORT=8881 \
 feuyeux/grpc_client_kotlin:1.0.0

Docker-Mesh-Kube

• build and publish docker image
• running on kube
• running above service mesh
• support open tracing
• transcoder(Http2gRPC)
