Dapr connect-go Example

This repository reproduces the example at https://connect.build/docs/go/getting-started for Dapr between connect-go and grpc-go implementations.

Setup

Prerequisites

• Docker
• Dapr
• Go 1.18+

dapr init
# Run the consul instance for discovery
./run-consul.sh

We're running consul as a replacement for mDNS which may not work correctly in all environment.

Running the examples

In a terminal, run either the grpc or connect server with dapr:

./run-grpc-server.sh

In a second terminal, run either the grpc or connect client with dapr:

./run-grpc-client.sh

The gzip compression issue happens when you use both connect-client and connect-server implementations.

Protobuf Generation

The proto code was generated as such:

connect-go

buf lint
buf generate

grpc-go

protoc --go_out=. --go_opt=paths=source_relative \
    --go-grpc_out=. --go-grpc_opt=paths=source_relative \
greet/v1/greet.proto
