feat(helm): add Gateway API HTTPRoute support by luqs1 · Pull Request #574 · cnoe-io/ai-platform-engineering

luqs1 · 2026-01-07T12:14:22Z

Add support for Kubernetes Gateway API HTTPRoutes as an alternative to Ingress resources. When global.gatewayApi.enabled is true, HTTPRoutes are created instead of Ingress resources (mutually exclusive).

Features:

Global configuration for gateway name and namespace reference
HTTPRoute templates for agent-ontology, rag-redis, and rag-webui
Mutual exclusion logic between Ingress and HTTPRoute
Support for cross-namespace gateway references
Disabled by default for backwards compatibility
PathType mapping from Ingress (Prefix) to Gateway API (PathPrefix)

Also fixes bug in rag-webui ingress template where hostname wasn't extracted correctly from values structure.

Preserve host-specific paths when generating HTTPRoutes

HTTPRoute hostnames are defined at the route level and apply to all rules. This template builds rules by iterating each host’s .paths (lines 28–32) after populating the hostnames list from all hosts, so if .Values.ingress.hosts contains multiple hosts with different path lists, every path becomes valid for every hostname. That changes routing behavior versus the Ingress template and can send requests for host B to paths intended only for host A. Consider creating separate HTTPRoute objects per host or grouping rules by hostname to keep paths scoped.

Useful? React with 👍 / 👎.

Preserve host-specific paths when generating HTTPRoutes

As written, rules are generated by iterating each host’s .paths (lines 28–32), but hostnames are specified at the route level and apply to all rules. If .Values.ingress.hosts contains multiple hosts with different paths, those paths become shared across all hostnames, changing behavior compared with the Ingress template. This can route host-specific paths to the wrong hostname. Consider emitting one HTTPRoute per host or otherwise scoping rules so host/path associations are preserved.

…support This commit addresses two limitations in the Gateway API HTTPRoute implementation: 1. Per-service control for HTTPRoute rendering: - Added httproute.shouldRender helper to rag-stack subcharts (agent-ontology, rag-redis, rag-webui) - HTTPRoute now respects BOTH global.gatewayApi.enabled AND ingress.enabled flags - Users can now disable HTTPRoute for specific services while keeping Gateway API enabled globally 2. Gateway API support for main agent charts: - Added complete HTTPRoute support to supervisor-agent, agent (generic), and backstage-plugin-agent-forge - Implemented 6 new helper templates per chart: * gatewayApi.enabled - Check global Gateway API flag * gatewayApi.gatewayName - Get gateway name from global config * gatewayApi.gatewayNamespace - Get gateway namespace (defaults to release namespace) * gatewayApi.pathType - Map Ingress pathType to Gateway API pathType * httproute.shouldRender - Render when BOTH ingress.enabled AND gatewayApi enabled * ingress.shouldRender - Render when ingress.enabled AND gatewayApi NOT enabled - Created HTTPRoute templates for all 3 main agent charts - Updated ingress templates to use new shouldRender helper for mutual exclusivity Testing: - Verified mutual exclusivity (Ingress XOR HTTPRoute) - Verified per-service HTTPRoute disable functionality - Verified pathType mapping (Prefix → PathPrefix) - Verified cross-namespace gateway references - All helm template tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> Signed-off-by: Luqmaan <luqmahme@cisco.com>
