Overview

This design adds support for Kubernetes Gateway API's HTTPRoute resource as an alternative to
Ingress and OpenShift Route for external access to Vault.

Background

The Gateway API (https://gateway-api.sigs.k8s.io/) is the successor to Ingress, offering:
• More expressive routing (header-based, query parameter matching)
• Role-oriented design (Gateway/HTTPRoute separation)
• Vendor-neutral, extensible API
• Better support for advanced traffic management

Proposed Values Schema

  server:
    # Gateway API HTTPRoute configuration
    # Requires Gateway API CRDs to be installed in the cluster
    # See: https://gateway-api.sigs.k8s.io/guides/getting-started/
    httpRoute:
      enabled: false

      # Labels to add to the HTTPRoute
      labels: {}

      # Annotations to add to the HTTPRoute
      annotations: {}

      # Gateway references (parentRefs) - required
      # At least one gateway must be specified
      parentRefs:
        - name: my-gateway
          namespace: gateway-namespace  # optional
          sectionName: https            # optional, gateway listener name

      # Hostnames for the route
      hosts:
        - vault.example.com

      # When HA mode is enabled, point to the active service
      activeService: true

      # HTTPRoute rules - if empty, creates a default catch-all rule
      rules: []
      # Example with path matching:
      # rules:
      #   - matches:
      #       - path:
      #           type: PathPrefix
      #           value: /
      #     filters: []  # optional filters (e.g., header modification)
