[Bugfix] Grant destinationrules RBAC to the manager - #868
Merged
slin1237 merged 2 commits intoSep 9, 2026
Conversation
The traffic reconciler picks its translator at startup by probing
CRDs (reconcilers/traffic/factory): if gateway.envoyproxy.io
BackendTrafficPolicy is absent but networking.istio.io
DestinationRule exists, the Istio translator is selected and the
manager registers a watch on DestinationRule.
The manager ClusterRole only granted networking.istio.io/sidecars,
so on such a cluster the informer's list call is rejected:
destinationrules.networking.istio.io is forbidden: User
"system:serviceaccount:ome:ome-controller-manager" cannot list
resource "destinationrules" ... at the cluster scope
The cache never syncs, and the manager exits after the cache-sync
timeout ("Could not wait for Cache to sync"), looping every two
minutes. Webhooks keep answering, but nothing is reconciled.
Seen on a cluster that carries a partial Istio CRD set (Higress
installs destinationrules but not virtualservices), so the failure
does not need a real Istio control plane to trigger.
Add the kubebuilder rbac marker next to the existing sidecars one,
regenerate config/rbac/role.yaml with controller-gen, and sync it
into the chart. The chart render test now asserts that the manager
ClusterRole grants every backend-policy resource a traffic
translator can watch (destinationrules, backendtrafficpolicies);
it fails on the previous role.yaml.

- Around line 478-480: Update the validation loop for destinationrules and
backendtrafficpolicies to assert each ClusterRole rule includes the correct API
group, resource, and both list and watch verbs, rather than checking only the
resource name. Preserve the existing failure behavior and translator resource
coverage.

The translator-resource check only looked for the resource name in the rendered ClusterRole, so a rule that names destinationrules without list/watch would still pass and reintroduce the cache-sync timeout. Walk the rendered rules and require, in one rule, the API group, the resource, and both list and watch. Fails when the resource is absent and when only the watch verb is dropped from the rule; passes on the current role.yaml. Signed-off-by: weetime <8436592+weetime@users.noreply.github.com>

What
The manager ClusterRole never granted
networking.istio.io/destinationrules, but the traffic reconciler watchesDestinationRulewhenever the CRD exists and the Envoy GatewayBackendTrafficPolicyCRD does not (reconcilers/traffic/factorypicks the Istio translator). On such a cluster the informer's list call is forbidden, the cache never syncs, and the manager exits on cache-sync timeout every two minutes:Webhooks keep answering during the loop, so the symptom is "InferenceService status stops updating" rather than an obvious crash.
This does not need a real Istio control plane: a partial Istio CRD set (e.g. the one Higress ships, which has
destinationrulesbut notvirtualservices) is enough to select the translator.Fix
