Consul-based Control Plane for Envoy Proxy

Raven

Raven is a control plane for Envoy Proxy that is basing its service discovery on Consul.

Envoy Proxy supports a lot of different types of service discoveries:

• LDS: Listener Discovery Service: what to listen to;
• CDS: Cluster Discovery Service: what apps are available;
• And a lot more, soon to be implemented.

Usage

HOST_ADDRESS=host.docker.internal make

This should spin up Raven. Now you can start Envoy

make envoy

It is strongly recommended to start Envoy interactively but it works either way.

Environment variables

* `GRPC_BINDING` : where raven will expose its gRPC interface (default: `127.0.0.1:1984`)
* `CONSUL_URL` : where Consul is located (default: `localhost:8500`)
* `HOST_ADDRESS` : address to use if the service address is `localhost` (useful with Docker for Mac)

TODO

• Implement remaining Service Discoveries
• Implement AggregatedServiceDiscovery
• Use flags along with environment variables
