Provides an Envoy xDS monitor for async-service-supervisor.
async-service-supervisor-envoy publishes supervised worker endpoints to Envoy:
- xDS control plane - Runs an ADS server backed by
async-grpc-xds. - Supervisor integration - Registers and removes endpoints from supervisor worker lifecycle events.
- Multiple clusters - Groups workers by
state[:name]by default. - Endpoint contract - Converts concrete post-bind worker listeners into Envoy upstream endpoints, including grouped IP or Unix socket addresses.
- Delegate mapping - Uses a delegate object for endpoint selection, cluster grouping, and health without active probing.
- Load-aware balancing - Optionally reports per-worker CPU utilization and request throughput to Envoy using out-of-band ORCA.
Please see the project documentation for more details.
- Getting Started - This guide explains how to use
async-service-supervisor-envoyto publish supervised worker endpoints to Envoy using xDS.
Please see the project releases for all releases.
- Publish configured active health checks with Envoy clusters.
- Add Bake tasks for inspecting Envoy monitor status, clusters, and endpoints.
- Add supervisor-driven out-of-band ORCA load reporting for independently addressable workers.
- Accept the required Falcon listener as a positional worker preparation argument.
- Deduplicate immutable endpoint values reported by multiple supervised workers and aggregate their health.
- Register concrete Falcon cluster listeners as Envoy upstream endpoint state after binding.
- Publish grouped IP and Unix-domain-socket endpoint addresses to Envoy.
- Configure generated clusters from each endpoint's supported HTTP protocol names.
- async-service-supervisor - Supervisor for managed Async service workers.
- async-grpc-xds - xDS support for Async::GRPC.
- Envoy xDS - Envoy dynamic configuration protocol.
