Orion Proxy is a high performance and memory safe implementation of popular Envoy Proxy. Orion Proxy is implemented in Rust using high-quality open source components.

Memory Safety

Rust programming language allows to avoid a whole lot of bugs related to memory management and data races making Orion Proxy a very robust and secure application.

Performance

Orion Proxy offers 2x-4x better throughput and latency than Envoy Proxy. Refer to Performance to see performance figures and for more details how we tested Orion Proxy .

Compatibility

Orion Proxy configuration is generated from Envoy's xDS protobuf definitions. Orion Proxy aims to be a drop in replacement for Envoy.

git clone https://github.com/kmesh-net/orion
cd orion
git submodule init
git submodule update --force
cargo build

cargo run --bin orion -- --config orion/conf/orion-runtime.yaml

Build and run with Docker:

# Build
docker build -t orion-proxy -f docker/Dockerfile .

# Run
docker run -p 8000:8000 --name orion-proxy orion-proxy

# Verify service
curl -v http://localhost:8000/direct-response # Should return HTTP 200 with "meow! 🐱"

For testing load balancing with real backend servers:

# Start two nginx containers
docker run -d -p 4001:80 --name backend1 nginx:alpine
docker run -d -p 4002:80 --name backend2 nginx:alpine

# Start Orion Proxy (uses host networking to access localhost:4001/4002)
docker run -d --network host --name orion-proxy orion-proxy

# Test load balancing
curl http://localhost:8000/  # Proxies to nginx backends!

# Cleanup
docker rm -f backend1 backend2 orion-proxy
