envoy-xds-controller

A Kubernetes-native control plane for Envoy proxies that provides dynamic configuration management through the xDS API.

Description

Envoy xDS Controller is a Kubernetes controller that manages Envoy proxy configurations through the xDS API. It allows defining Envoy configurations as Kubernetes Custom Resources (CRs) and automatically transforms them into Envoy configurations, which are delivered to proxies via the xDS protocol in real-time.

Key features:

• Full support for Envoy xDS v3 API (LDS, RDS, CDS, SDS)
• Kubernetes-native integration with controller-runtime
• Dynamic configuration updates without proxy restarts
• Authentication and authorization with OIDC and RBAC
• Templating system for configuration reuse
• Web UI for configuration management
