KxDS

KxDS is an Envoy discovery service implementation for Kubernetes. KxDS runs as a sidecar next to Envoy and configures the proxy to expose Kubernetes services.

Features

• Service Discovery KxDS watches Kubernetes for ClusterIP services with a http named port
• Envoy Clusters (CDS) are generated for each Kubernetes service in the form <name>-<namespace>-<http-port>
• Envoy Routes (RDS) are generated for each cluster and mapped to the <name>.<namespace> domain
• Envoy Listeners (LDS) KxDS configures Envoy to listen on port 8080 and sets up retry policies for each route
