Heads-up on overlap: #2584 makes the same v1.3.1 → v1.5.0 bump for the same K8s 1.37 CEL cost-budget reason. It was opened at 14:00 today and has been through review, so the two will conflict on This PR catches something #2584 does not: the v1.5.0 RBAC split. Confirmed against the pinned chart — Going the other way, #2584 carries two things this PR does not:
Happy to close #2584 and port the docs section here, or fold the RBAC scoping into #2584 — whichever you prefer. Flagging rather than picking, since it is your PR. |
The kindest/node bump to v1.37.0 (#2583) put KWOK on a Kubernetes 1.37 apiserver, which enforces a stricter CEL cost budget on CRD validation rules. The pinned agentgateway/agentgateway-crds v1.3.1 charts declare 90 unbounded 'type: string' fields carrying x-kubernetes-validations rules, so 1.37 rejects the CRDs outright with 'estimated rule cost exceeds budget by factor of 16.1x'. Every inference recipe has been red on main since. Chart v1.4.0 added the maxLength bounds that make the cost estimable and v1.5.0 replaced those CEL rules with plain 'pattern:'. Verified against real apiservers via envtest: v1.3.1 is rejected on 1.37 and accepted on 1.36, while v1.5.0 is accepted on both, so the pin moves without gating and kind stays on 1.37. Also scope the controller's new write RBAC. v1.5.0 splits RBAC into a cluster-wide read role plus a write-capable '-deployer' ClusterRole covering Deployments, DaemonSets, Secrets, and ServiceAccounts, and binds it with a ClusterRoleBinding when rbac.gatewayNamespaces is empty. v1.3.1 granted no DaemonSet write at all, so adopting the chart unchanged would hand a network-facing controller a privileged-DaemonSet-on-every-node primitive. AICR provisions exactly one Gateway, in agentgateway-system, so pin rbac.gatewayNamespaces to that namespace: the write role is then bound by a namespaced RoleBinding and cluster-wide read is unchanged.

Namespace-scoping the controller's write RBAC reduces cross-namespace blast radius, but it does not confine pod privileges or node placement: a DaemonSet created inside agentgateway-system still lands a pod on every node, and the namespace carries no Pod Security Admission labels. Correct the values comment to say so and name admission control as the control for node reach rather than implying RBAC covers it. Also document what an agentgateway pin bump means for operators. AICR bundles create only an AgentgatewayParameters and the inference-gateway Gateway, so upstream breaking changes land on surface AICR never populates; resources a user authors themselves are exposed and AICR can neither detect nor migrate them. Give the detection command and record that CI exercises fresh installs of a pinned chart, not in-place upgrades. Fixes: #2584 Signed-off-by: Mark Chmarny <mark@chmarny.com>
…e scoping Four gaps in the upgrade guidance. The detection command named agentgatewaymodels explicitly, but that kind only exists from chart v1.4.0, so it fails with 'the server doesn't have a resource type' on exactly the older pins whose operators need to run it. Discover the kinds from the cluster instead. The check also failed open: an unhealthy aggregated APIService makes kubectl api-resources exit non-zero, the substitution yields an empty list, the loop body never runs, and the operator reads 'nothing found' as clear. Capture the status and exit. It missed operator-authored routes. HTTPRoute and GRPCRoute live in the Gateway API group, so the agentgateway.dev sweep cannot see them - and they are what the cross-namespace route delegation change affects, which this same section enumerates as a breaking change. rbac.gatewayNamespaces was documented only in a values.yaml comment despite being a user-visible behavior change with a silent failure mode. Document what scoping does and does not buy, that a Gateway outside the listed namespaces never gets an address, and how to inventory existing Gateways before upgrading plus the must-already-exist and --set-json constraints.

Pushed The description was for a different change. It described generated wrapper charts hardcoding Four fixes to the docs section, keeping your prose and structure:
Your correction to the values comment is right and I left it as written: scoping confines the write reach, not pod privileges or node placement, since a DaemonSet created in a permitted namespace still lands on every node. The docs section says the same. On the CI failures — the KMS lanes are a Sigstore Rekor outage (503s during signing) and the argocd lanes are the recurring kube-prometheus health timeout under KWOK. I checked the logs on both: no agentgateway, CEL, or RBAC errors in either. |

A route whose parentRefs names another HTTPRoute rather than a Gateway is delegated, and from v1.5.0 cross-namespace delegation requires a ReferenceGrant in the child's namespace where previously none was needed. The route inventory surfaced those rows but did not say what to do with them. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…rator's shell Two corrections to the gateway-namespace-scoping guidance. The section credited scoping with removing cluster-wide Secret read. It does not. The controller's read ClusterRole carries get/list/watch on secrets and is bound by a ClusterRoleBinding emitted outside the rbac.gatewayNamespaces conditional, so it is identical under both renders - only the -deployer write binding flips to per-namespace RoleBindings. An operator checking whether the gateway can reach their application Secrets would have read this and concluded it cannot. Move the read alongside daemonsets as something scoping does not contain. The diagnostics also used '|| exit 1', which terminates an interactive shell and closes the terminal of anyone pasting them in. Report to stderr instead; the fail-closed guarantee is unchanged, and an empty-but-successful discovery is now distinguished from a failed one. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

…rs to judge The paragraph told operators to distinguish a parent that is a Gateway from a parent that is another HTTPRoute, but the command printed parent names only, so the two were indistinguishable and the one-shot inventory could not be acted on without describing every route individually. It also dropped upstream's qualifier. The v1.5.0 ReferenceGrant requirement applies to CROSS-namespace route-to-route delegation; same-namespace delegation is unaffected. Saying delegated routes generally need a grant errs safe but sends operators after work the change does not require. Adding PKIND and PNS columns fixes both, since parentRefs[].namespace is optional and renders empty for a same-namespace parent - precisely the cross-namespace signal. Note the multiple-parentRefs misalignment case, where JSONPath omits missing entries rather than padding them. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
Replacing '|| exit 1' with '|| echo' stopped the diagnostics from closing an interactive shell, but it also made all three of them return status 0 when kubectl fails - the echo succeeds, so the pipeline succeeds. An automated pre-upgrade check would read a failed inventory as a clean one, which is the opposite of the fail-closed behavior the guidance claims. Wrapping each block in a subshell gets both properties: exit 1 propagates as the block's status, and it does not terminate the operator's shell. Two related corrections. The first section concluded 'the upgrade needs nothing from you' before the Gateway inventory ran. A cluster with no custom agentgateway resources and no routes can still hold an agentgateway Gateway outside agentgateway-system, which stops reconciling under scoped RBAC. Point at that inventory before drawing the conclusion. The failed reconciliation is not visible only in controller logs: v1.5.0 sets Programmed=False with reason DeploymentFailed on the Gateway when the generated-resource writes are denied, so status.conditions carries the cause. Also widen the misalignment inspection command to grpcroute, since the listing it follows covers both kinds. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

Kubernetes Gateway API ReferenceGrant spec.from spec.to cross-namespace route delegation v1.5.0
💡 Result:
In Kubernetes Gateway API v1.5.0, the ReferenceGrant resource is a mechanism used to securely enable cross-namespace references, such as a Route in one namespace referencing a Service or Secret in another [1][2][3]. Without a ReferenceGrant, implementations must not permit such cross-namespace references [4][3]. The spec field of a ReferenceGrant consists of two primary lists, from and to, which define the trust relationship [1][3]. Both lists use an OR logic, meaning any entry in these lists can satisfy the requirement [5][6]. From (spec.from) The from list specifies the sources allowed to reference resources in the target namespace [1]. Each entry defines [6]: - group: The API group of the referent (e.g., gateway.networking.k8s.io) [6]. - kind: The kind of the referent (e.g., HTTPRoute, TCPRoute) [6]. - namespace: The namespace from which the reference is allowed to originate [1][6]. To (spec.to) The to list specifies the resources within the current namespace that are permitted to be referenced by the sources defined in the from list [1]. Each entry defines [6]: - group: The API group of the target resource [1]. - kind: The kind of the target resource (e.g., Service) [1]. Important Constraints: - Namespace Limitation: The to list does not include a namespace field because a ReferenceGrant only allows references to resources within the same namespace as the ReferenceGrant object itself [1][3]. - Additive Nature: ReferenceGrants are purely additive; multiple grants can exist to expand the set of trusted relationships, and they cannot conflict with one another [1]. - No Names: Resource names are intentionally excluded from the from section to prevent insecure configurations, as name-based restrictions are easily bypassed by renaming resources [1]. - Required Handshake: This mechanism ensures that the owner of a resource in a target namespace must explicitly opt-in to allow external references [7][3].

site:gateway-api.sigs.k8s.io v1.5 route-to-route delegation ReferenceGrant parentRefs namespace
💡 Result:
In Kubernetes Gateway API v1.5, ReferenceGrant is the standard mechanism for authorizing cross-namespace references [1][2]. It acts as a mandatory "handshake" to ensure security when one resource (like a Route) needs to reference another (like a Service or Secret) located in a different namespace [1][3]. ReferenceGrant Mechanics: - Scope: A ReferenceGrant must be created in the same namespace as the target resource (the resource being referenced) [1]. - Authorization: The grant explicitly lists authorized "from" sources (group, kind, and namespace) and "to" targets (group and kind) [1]. - Cross-Namespace Enforcement: Without a valid ReferenceGrant, any cross-namespace reference is considered invalid and must be rejected by the implementation [1][4]. Regarding ParentRefs and Route-to-Route Delegation: - ParentRefs: The parentRefs field in a Route defines the parent resources (e.g., Gateway) to which the Route attaches [5]. While ReferenceGrant is used for backend or secret references across namespaces, it is not used to govern ParentRefs to Services [5]. The attachment of a Route to a parent (like a Gateway) is handled by the parent resource's own configuration, such as the Gateway's ability to allow attachment from specific Routes [5]. - Route-to-Route Delegation: While ReferenceGrant enables general cross-namespace references, explicit "Route-to-Route delegation" (where a Route includes another Route) remains a conceptual or future-facing feature often discussed in the context of GEP-709 [6]. As of v1.5, standard Gateway API behavior focuses on routes referencing backends in other namespaces (e.g., Services) [1][3]. In summary, ReferenceGrant provides the security handshake for cross-namespace references to backends or secrets, but it does not apply to the parentRefs mechanism used for Route-to-Gateway or Route-to-Service parent attachments [5][1].

Gateway API GEP-709 route-to-route delegation ReferenceGrant parentRef v1.5 official
💡 Result:
In Gateway API v1.5, the ReferenceGrant resource is a core component used to enable cross-namespace references, but it is not utilized for route-to-route delegation. GEP-709 introduced the ReferenceGrant resource specifically to address cross-namespace forwarding (e.g., a Route in one namespace referencing a Service in another) [1][2]. While GEP-709 initially explored how ReferenceGrant could potentially facilitate route-to-route inclusion and delegation, the final design of GEP-709 explicitly separated these concepts, leaving route-to-route delegation for future exploration [1]. Key distinctions regarding these features in Gateway API v1.5 include: ReferenceGrant (Stable in v1.5): As of v1.5, ReferenceGrant has been promoted to v1 and is included in the Standard channel [3][4]. It serves as a handshake mechanism allowing resources in one namespace to trust references from another [5][6]. It is primarily used for cross-namespace references between objects like Routes and Services (or Secrets), not for delegating Route rules between different Route objects [5][6]. Route-to-Route Delegation: Route-to-route delegation remains a distinct architectural challenge in the Gateway API [7]. Although early discussions on GEP-709 and related issues (such as GEP-1058) considered reusing the same reference and attachment patterns (like ParentRef) for route-to-route interaction, these were not implemented as part of the ReferenceGrant framework [1][8][7]. Currently, the Gateway API handles delegation primarily through the attachment of Routes to Gateways, not through explicit route-to-route delegation via ReferenceGrant [5][9]. For official technical documentation on how to configure cross-namespace references in v1.5, you should consult the Gateway API ReferenceGrant documentation, which outlines the current supported use cases for cross-namespace security handshakes [5][9][6].

💡 Result:
In agentgateway v1.5.0, cross-namespace route delegation has been updated to require a ReferenceGrant for authorization, aligning with standard Gateway API security practices [1][2]. Previously, parent routes could delegate to child HTTPRoutes across namespaces without explicit authorization from the child namespace [1][2]. Key changes and requirements for cross-namespace delegation include: 1. Mandatory ReferenceGrant: When a parent HTTPRoute delegates to a child HTTPRoute in a different namespace, you must now create a ReferenceGrant in the child's namespace [1]. This grant must authorize the parent's namespace to reference the child's HTTPRoute [1]. 2. Configuration Example: The ReferenceGrant must specify the child's namespace and allow references from the parent's namespace for the HTTPRoute kind [1]. apiVersion: gateway.networking.k8s.io/v1beta1 kind: ReferenceGrant metadata: name: allow-parent-delegation namespace: spec: from: - group: gateway.networking.k8s.io kind: HTTPRoute namespace: to: - group: gateway.networking.k8s.io kind: HTTPRoute 3. Role of parentRefs: On a delegated child HTTPRoute, the parentRefs field remains informational for status reporting back to the parent [3][4]. It does not control authorization for delegation [3]. Authorization is now explicitly governed by the ReferenceGrant [1][2]. This change ensures that cross-namespace attachments are explicitly permitted by the owner of the child route, preventing unauthorized cross-namespace route adoption [2]. Delegation within the same namespace is unaffected by this requirement [1].

Inspect ReferenceGrant authorization fields. The v1.5.0 CRD prints only Age, so kubectl get referencegrants -A does not show spec.from or spec.to. Inspect these fields to confirm that each grant allows the parent HTTPRoute namespace and kind to reference the child HTTPRoute; object presence alone does not prove coverage.

Approving. Noting for the record that I authored five of the seven commits here — the docs corrections across the review rounds — so this is not an independent review of that half. The substantive change is yours: the v1.5.0 pin bump and the rbac.gatewayNamespaces scoping, both of which I verified against the rendered charts rather than the release notes.
What I checked: v1.3.1 declares 90 rule: matches(self, …) CEL rules and v1.5.0 declares none, with the offending duration fields now carrying maxLength: 32 plus pattern — so the version floor is real and v1.4.0 is correctly identified as the earliest fix. AgentgatewayParameters is schema-identical across the two versions for every field AICR sets. The agentgatewaymodels health-check assertion holds because the CRDs chart templates that definition unconditionally, while agentgatewayModels.enabled gates controller support only. The RBAC scoping covers every namespace AICR provisions a Gateway in, and rendering both ways confirms it flips only the -deployer write binding — the cluster-wide read binding, Secrets included, is unaffected either way.
CI: gate was green on the prior head and is re-running here. The KMS lanes' earlier failures were a Sigstore Rekor outage that has since cleared; the argocd lanes fail intermittently on a kube-prometheus health timeout under KWOK, unrelated to this diff.
Enabling auto-merge so this lands as soon as the gates are satisfied, rather than sitting and going stale — the repo requires up-to-date branches and dismisses approvals on any push, so a catch-up rebase after approval would just cost this approval.
Widening the command to httproute,grpcroute made kubectl expand it into a lookup for each kind against the same name, so whichever kind the route is not always returns NotFound. Name the kind that matches the row instead. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

Re-approving after 97c8e4bfa, a one-line docs fix: the inspection command named both route kinds, which makes kubectl expand it into a lookup per kind against the same name, so whichever kind the route is not always returned NotFound. It now names a single kind.
That defect came from my own previous fix — widening the command to cover GRPCRoute introduced it. Same for the round before, where replacing || exit 1 with || echo stopped closing the operator's shell but made every check return 0. Both are now correct, and the shell blocks are verified with bash -n.
Everything from my prior approval stands: the pin bump and RBAC scoping are yours and were verified against the rendered charts, and my commits are the docs corrections raised across the review rounds.
Enabling auto-merge.
…ence rke2-inference pinned agentgateway and agentgateway-crds to v2.2.1 because the registry default at the time, v1.3.1, was too old to watch TLSRoute at v1alpha2. NVIDIA#2587 moved that default to v1.5.0, which is built against a newer Gateway API client and carries tlsroutes and tlsroutes/status in its role, so the reason for the pin no longer holds. Keeping it would be actively harmful. agentgateway-crds v2.2.1 still declares 39 unbounded 'rule: matches(self, ...)' CEL rules where v1.5.0 declares none, so a Kubernetes 1.37 apiserver rejects its CRDs for exceeding the cost budget - the exact failure NVIDIA#2587 fixed. The v2.2.x line is an older schema line, so pinning to it is a downgrade that reintroduces the break on every rke2 and VR200 inference recipe. Drop both pins so they track the registry default, remove the two now-obsolete versionPinExemptions entries, and update the comments that named the version.

agentgatewayandagentgateway-crdsfromv1.3.1tov1.5.0so their CRDs install on Kubernetes 1.37, scopes the controller's write permissions to the one namespace AICR provisions a Gateway in, and documents both for operators.Motivation / Context
agentgateway-crdsv1.3.1 declares CEL validation rules of the formrule: matches(self, ...)on duration strings with nomaxLength. With the length unbounded the apiserver's estimated cost exceeds its budget — by 16.1x for the worst rule. Kubernetes 1.37 enforces that budget where 1.36 did not, so CRD install fails:This surfaced when #2583 bumped
kindest/nodetov1.37.0, turning every inference lane red. It is not a defect introduced by that bump — the rules were always over budget, 1.36 simply did not enforce it. v1.4.0 is the version floor: it bounded those fields withmaxLength, which is exactly the remedy the apiserver error recommends.The bump also brings v1.5.0's RBAC split, which is why this PR sets
rbac.gatewayNamespaces. Left at the chart's empty default, the write-capable-deployerClusterRole is bound with aClusterRoleBinding, giving a network-facing controller write on Deployments, DaemonSets, Secrets, ServiceAccounts, ConfigMaps, Services, HPAs and PDBs in every namespace.Fixes: N/A

Type of Change
Component(s) Affected
pkg/recipe)docs/,examples/)Implementation Notes
Both components are pinned only by
defaultVersioninrecipes/registry.yaml, andrecipes/mixins/platform-inference.yamlwires them with no version field, so this reaches every inference recipe rather than any single leaf — which is the set whose golden digests move.rbac.gatewayNamespacesis scoped toagentgateway-systembecause that is the only namespace AICR provisions a Gateway in (recipes/components/agentgateway/manifests/inference-gateway.yaml), with no overlay override. Scoping narrows the write blast radius; it does not make the controller unprivileged, since the role still grantsdaemonsetsand a DaemonSet in a permitted namespace still lands on every node.The health check gains an
Established=Trueassertion foragentgatewaymodels.agentgateway.dev, the fourth CRD v1.5.0 adds. The app chart'sagentgatewayModels.enabled: falsedefault does not suppress it — that value gates controller support, while the CRDs chart templates the definition unconditionally.docs/user/component-catalog.mddocuments both changes for operators: what a pin bump across breaking releases means, and what gateway-namespace scoping does and does not buy. The detection commands discover kinds from the cluster rather than naming them, because the API group grows across versions and a named command fails on exactly the older pins that need checking; they also fail closed, so an unhealthy aggregated APIService cannot be mistaken for a clean result.Testing
make update-goldens make bom-docs go test ./pkg/bundler/ ./pkg/recipe/...Both parity goldens and the BOM freshness tests pass. The fix is confirmed end-to-end by CI: 14 inference lanes green on
kindest/node:v1.37.0, against the same lanes failing on #2520 with the v1.3.1 pin.Verified against the pulled charts rather than release notes alone: v1.3.1 declares 90
rule: matches(self, ...)CEL rules and v1.5.0 declares none, the offending duration fields now carryingmaxLength: 32pluspattern.AgentgatewayParametersis schema-identical across the two versions for every field AICR sets, so nothing is pruned.Two classes of CI failure seen on earlier heads were external and are not caused by this diff: the KMS signing lanes failed on a Sigstore Rekor outage (503s while writing the transparency log entry), and several argocd lanes fail intermittently on a kube-prometheus health timeout under KWOK. The failing logs contained no agentgateway, CEL, or RBAC errors. The Rekor outage has since cleared.
Risk Assessment
A shared component every inference recipe consumes, so the blast radius is all inference lanes; but it is a registry pin plus one values key, fully covered by the CI inference matrix, and trivially revertible.
Rollout notes: The CRD schema change is compatible —
maxLength: 32lands on strings that already had to match a pattern bounded well under 32 characters, so existing valid resources continue to validate. v1.5.0 is a net privilege reduction versus v1.3.1 and ClusterRole names are unchanged, sohelm upgradeis clean.Two upgrade cases need operator attention, both now documented: a Gateway using the
agentgatewayGatewayClass outsideagentgateway-systemstops reconciling once the namespace list is scoped without it, and user-authoredAgentgatewayPolicy/AgentgatewayBackendor delegated cross-namespaceHTTPRouteobjects are subject to upstream's breaking changes. AICR generates none of these, so AICR-generated bundles are unaffected.CI exercises fresh installs, not in-place upgrades from an older pin.
