Description

Renames 38 entries in internal/config/default_config.go from the singular Kubernetes kind name to the plural resource name, so their informers watch a path that actually exists.

internal/pipeline/step.go:46 passes each entry straight to the dynamic informer:

gvr, _ := schema.ParseResourceArg(ri.config.Name)
iclient := ri.informer.ForResource(*gvr)

ParseResourceArg only splits the string and there is no RESTMapper or discovery lookup, so the first segment becomes the resource path verbatim. job.v1.batch therefore lists and watches /apis/batch/v1/job rather than /apis/batch/v1/jobs, and never syncs. The same applies to Events, ServiceAccounts, Roles, RoleBindings, ClusterRoleBindings, NetworkPolicies, ResourceQuotas, LimitRanges, Leases, HorizontalPodAutoscalers, PodDisruptionBudgets, CustomResourceDefinitions, ControllerRevisions, the CSI resources and the webhook configurations.

The convention is already correct elsewhere in the repo: the first block of default_config.go (pods.v1., deployments.v1.apps, endpointslices.v1.discovery.k8s.io) and every entry in the whitelist in internal/config/config_local.go use plurals.

Scope

This PR only renames entries whose plural form is a real listable resource. Nothing is added or removed, so the change is limited to making already-configured resources work.

Deliberately left out of this PR, because they need a maintainer decision rather than a rename, as discussed in #599:

  • Create-only endpoints that no informer can watch: tokenreview, tokenrequest, subjectaccessreview, selfsubjectaccessreview, selfsubjectrulesreview, selfsubjectreview, localsubjectaccessreview, binding.
  • Entries that are not Kubernetes API resources: container.v1.core, service.apis, volume.v1..
  • node.v1. at line 261, a duplicate of nodes.v1. at line 31.

Three renamed entries are alpha APIs that many clusters will not serve (podschedulingcontexts, resourceclaims/resourceclaimtemplates/resourceclasses on v1alpha2.resource.k8s.io, storageversions). They are renamed for consistency; whether they belong in the default set at all is worth deciding separately.

Notes

Kubernetes Events need more than this rename to be useful: ParseList in pkg/model/model_converter.go keeps only the generic object fields, so reason, message/note, regarding and count are still dropped. Tracked in #599.

go build ./..., go vet ./... and go test ./... all pass.

📝 Walkthrough

Walkthrough

The default Kubernetes pipeline configuration now uses plural resource identifiers and corrected API group/version values across ingress, workload, CSI, admission, policy, storage, and coordination resources.

Changes

Kubernetes resource identifier corrections

Layer / File(s) Summary
Correct default pipeline resource identifiers
internal/config/default_config.go
Updated pipeline resource names from singular to plural forms and corrected API group/version identifiers across the affected Kubernetes resources. All entries continue to publish to DefaultPublishingSubject.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟠 High · up to ea5f8

Although the PR fixes plural resource paths for 38 defaults, several unsupported or obsolete resource identifiers remain and can prevent affected clusters from synchronizing or becoming ready. Those entries should be updated or removed before merge.

Add regression coverage for default resource identifiers.

Add a table-driven test for the expected PipelineConfig.Name set. filterWhitelistedPipelines uses exact string equality, so an incorrect name, API version, or resource kind can silently exclude a default pipeline.

Update or remove unsupported default resource identifiers. For the pinned Kubernetes v0.35.3 API, update VolumeAttributesClass, IPAddress, and ServiceCIDR to v1; update ResourceClaim and ResourceClaimTemplate to v1; replace resourceclasses.v1alpha2.resource.k8s.io with deviceclasses.v1.resource.k8s.io; and remove podschedulingcontexts.v1alpha2.resource.k8s.io. These entries cannot sync and may block startup while the configured informers wait for every registration to become ready.
