Metadata API in destination service not configured for k8s Jobs

[siggy]

What is the issue?

I'm observing lots of failed to retrieve job from indexer warnings in the destination container logs, for pods belonging to Jobs:

linkerd2/controller/k8s/metadata_api.go

Lines 230 to 243 in 225ce93

	case "Job":
	parentObj, err = api.getByNamespace(Job, pod.Namespace, parent.Name)
	if err != nil {
	log.Warnf("failed to retrieve job from indexer %s/%s: %s", pod.Namespace, parent.Name, err)
	if retry {
	parentObj, err = api.client.
	Resource(batchv1.SchemeGroupVersion.WithResource("jobs")).
	Namespace(pod.Namespace).
	Get(ctx, parent.Name, metav1.GetOptions{})
	if err != nil {
	log.Warnf("failed to retrieve job from direct API call %s/%s: %s", pod.Namespace, parent.Name, err)
	}
	}
	}

It appears the metadata API client is only configured for Nodes and ReplicaSets:

linkerd2/controller/cmd/destination/main.go

Line 120 in 225ce93

metadataAPI, err := k8s.InitializeMetadataAPI(*kubeConfigPath, "local", k8s.Node, k8s.RS)

How can it be reproduced?

Start some k8s Jobs (I don't have a repro)?

Logs, error output, etc

seeing these warnings in the destination container:

2023-10-24T02:58:13.881735669Z time="2023-10-24T02:58:13Z" level=warning msg="failed to retrieve job from indexer [namespace]/[pod]: metadata informer (6) not configured"

output of linkerd check -o short

N/A

Environment

stable-2.14.1

Possible solution

Modify the call to InitializeMetadataAPI to include Job.
