kgateway-dev/kgateway v2.3.0-beta.1

on GitHub

🎉 Welcome to the v2.3.0-beta.1 release of the kgateway project!

Release Notes

Changes since v2.2.0-beta.6

Breaking Changes

• Agentgateway ExtAuth policies will now fail closed when the backendRef to the auth server is invalid (#13258)

New Features

• Add RequestID configuration to ListenerPolicy and HTTPListenerPolicy for controlling Envoy's UUID request ID behavior (#13240)
• Envoy data plane configuration via GatewayParameters now allows for strategic-merge-patch (overlays). This includes new envoy data plane support for PodDisruptionBudget, HorizontalPodAutoscaler, and VerticalPodAutoscaler. (#13266)
• Expose filterEnabled and filterEnforced configuration in TrafficPolicy LocalRateLimitPolicy. This allows users to control the percentage of requests for which the rate limit filter is enabled or enforced, useful for testing and gradual rollouts. ``` (#13272)
• Allow skipping controller Service creation via .controller.service.enabled: false.
  Allow full configurability for controller Services.
  (#13274)
• Both controllers' helm charts support HorizontalPodAutoscaler and VerticalPodAutoscaler (#13276)
• Added support for GRPCRoute attached policy. (#13293)
• Support GCP backends to route traffic to Google Cloud Platform services, such as Google Cloud Run (#13308)
• Support loadBalancerClass in envoy proxy service (#13328)
• Add support for priorityClassName to kgateway and agentgateway helm charts. (#13341)
• Add support for commonLabels in kgateway and agentgateway helm charts. (#13342)
• Default udp_max_queries to 100, and allow customizing it using GatewayParameters. (#13348)
• kgateway oauth2 policy: allow disabling set-cookie response
  header for token cookies.
  (#13383)

Bug Fixes

• Fixed the ancestor ref on AgentgatewayPolicy to resolve to Gateway. (#13281)
• For agentgateway controller, correctly merge and handle status from other controllers (#13316)
• (chore): use native go instead of curl pod to create http reqs by 1shubham7 (#13323)
• always add auto host rewrite to gcp route action (#13421)
• fix: AgentgatewayParameters did not merge resources or Istio configuration deeply when present on both GC and GW (#13468)

Deprecations

• Removed obsolete agentgateway configuration API from envoy-only GatewayParameters. (#13102)

Documentation

• Updates API docs regarding server-side apply (SSA) and AgentgatewayParameters (#13300)

Cleanup

• updated to use envoy 1.36.4; prep for multi-arch build (#13242)
• Enable krtequals linter checkUnexported option and fix all violations to ensure Equals() methods compare all relevant fields (#13275)
• Migrate inference pool plugin to use upstream EPP metadata constants from gateway-api-inference-extension package (#13280)
• [rustformation] create per config minijinja env (#13289)
• switch to rustformation by default (#13307)
• Helm charts are now published with both v-prefixed and non-prefixed version
