API versions: v1beta1, v1alpha2

Major Changes

ReferenceGrant moves to v1beta1, ReferencePolicy removed

With more implementations now supporting ReferenceGrant (and more conformance coverage of the resource), we've moved ReferenceGrant to v1beta1 in this release. Note that moving to beta also moves the object to the Standard channel (it was Experimental previously).

We've also removed the already-deprecated ReferencePolicy resource, so please move over to the shiny new ReferenceGrant, which has all the same features.

  • Promotes ReferenceGrant to the v1beta1 API and the standard release channel
    (#1455, @nathancoleman)
  • ReferencePolicy has been removed from the API in favor of ReferenceGrant.
    (#1406, @robscott)

Introduce GRPCRoute

The GRPCRoute resource has been introduced in order to simplify the routing of GRPC requests.
Its design is described in GEP-1016.
As it is a new resource, it is introduced in the experimental channel.

Thanks to @gnossen for pushing this ahead.

Status updates

As described in GEP-1364, status conditions have been updated within the Gateway resource to make it more consistent with the rest of the API. These changes, along with some other status changes, are detailed below.

Gateway:

  • New Accepted and Programmed conditions introduced.
  • Scheduled condition deprecated.
  • Core Conditions now Accepted and Programmed.
  • Moves to Extended: Ready.

Gateway Listener:

  • New Accepted and Programmed conditions introduced.
  • Detached condition deprecated.
  • Core Conditions now Accepted, Programmed, ResolvedRefs, and Conflicted.
  • Moves to Extended: Ready.

All Resources:

  • The Accepted Condition now has a Pending reason, which is the default until
    the condition is updated by a controller.

Route resources:

  • The Accepted Condition now has a NoMatchingParent reason, to be set on routes
    when no matching parent can be found.

The purpose of these changes is to make the status flows more consistent across objects, and to provide a clear pattern for new objects as we evolve the API.

Note: This change will require updates for implementations to be able to pass conformance tests. Implementations may choose to publish both new and old conditions, or only new conditions.

  • Adds Accepted and deprecates Detached Listener conditions and reasons (#1446, @mikemorris)
  • Adds Accepted and deprecates Scheduled Gateway conditions and reasons (#1447, @mikemorris)
  • Adds Pending reason for use with all Accepted conditions throughout the API (#1453, @youngnick)
  • Adds Programmed Gateway and Listener conditions, moves Ready to extended
    conformance (#1499, @LCaparelli)
  • Add RouteReasonNoMatchingParent reason for Accepted condition. (#1516, @pmalek)

Other Changes by type

Deprecations

  • GatewayClass, Gateway, and HTTPRoute are now only supported with the v1beta1
    version of the API. The v1alpha2 API versions of these resources will be fully
    removed in a future release. Additionally, v1alpha2 is marked as deprecated
    everywhere. (#1348 and #1405, @robscott)

API Changes

  • A new field responseHeaderModifier is added to .spec.rules.filters, which
    allows for modification of HTTP response headers (#1373, @aryan9600)
  • Display the Programmed condition instead of the Ready condition in the output
  • HTTPRoute: Validating webhook now ensures that Exact and Prefix path match
    values can now only include valid path values per RFC-3986. (RegularExpression
    path matches are not affected by this change). (#1599, @robscott)
  • RegularExpression type selectors have been clarified to all be
    ImplementationSpecific conformance. (#1604, @youngnick)

Documentation

  • Clarify that BackendObjectReference's Port field specifies a service port, not
    a target port, for Kubernetes Service backends. (#1332, @Miciah)
  • HTTPRequestHeaderFilter and HTTPResponseHeaderFilter forbid configuring
    multiple actions for the same header. (#1497, @rainest)
  • Changes "custom" conformance level to "implementation-specific" (#1436,
    @LCaparelli)
  • Clarification that changes to ReferenceGrants MUST be reconciled (#1429,
    @robscott)

Conformance Tests

  • ExemptFeatures have been merged into SupportedFeatures providing implementations
    a uniform way to specify the features they support.
    (#1507, @robscott) (#1394, @gyohuangxin)
  • To be conformant with the API, if there is no ReferenceGrant that grants a
    listener to reference a secret in another namespace, the
    ListenerConditionReason for the condition ResolvedRefs must be set to
    RefNotPermitted instead of InvalidCertificateRef. (#1305, @mlavacca)
  • A new test has been added to cover HTTP Redirects (#1556, @LiorLieberman)
  • Fix Gateway reference in HTTPRouteInvalidParentRefNotMatchingListenerPort
    (#1591, @sayboras)

Build Changes

Developer Notes

  • Deprecated v1alpha2 Go types are now aliases to their v1beta1 versions
    (#1390, @howardjohn)
