📝 Walkthrough

Walkthrough

Registered DRADeviceTaintRules with node ownership, Kubernetes scope, and enhancement metadata. Added it to the feature-status matrix. Updated HyperShift and self-managed HA manifests to disable this gate and revise related feature-gate entries.

Suggested reviewers: vr4manta

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 8ab0c

The change registers DRADeviceTaintRules while keeping it disabled in the reviewed feature-gate manifests, so it does not activate the feature or change runtime behavior.

All 3 techpreview presubmits failing to install the cluster here suggests there might be a wider issue, either TP is broken in payload or somehow enabling this gate is breaking the cluster bootstrap 🤔

[harche]

I dug into the artifacts for all three TechPreview failures. This is not a wider TP payload issue; enabling this gate without its companion API-enablement change is deterministically breaking cluster initialization.

The failure chain is:

1. kube-apiserver receives DRADeviceTaintRules=true, but --runtime-config does not enable resource.k8s.io/v1beta2.
2. kube-apiserver logs:

   Skipping API resource.k8s.io/v1beta2 because it has no resources.
   

3. Every production kube-scheduler then repeatedly logs:

   failed to list *v1beta2.DeviceTaintRule:
   the server could not find the requested resource
   

4. Kubernetes waits for all scheduler informer caches to sync before beginning scheduling. The DeviceTaintRule informer never syncs, so the production scheduler never becomes functional after the bootstrap scheduler exits.
5. OVN, Multus, MCO, OAuth, monitoring, etc. pods remain unbound; workers report no CNI configuration and the installer eventually times out.

The same scheduler error is present in all three jobs:

• e2e-aws-ovn-techpreview
• serial-techpreview-1of2
• serial-techpreview-2of2

cluster-kube-apiserver-operator#2275 supplies the missing SelfManaged mapping from DRADeviceTaintRules to resource.k8s.io/v1beta2. The existing API + CKASO payload run confirms that pairing works: installation and node readiness succeed, the API is served, and the scheduler reaches leader election. Its remaining blocking failure is only the old Origin assertion that expects v1beta2 to be absent.

One additional issue: the HyperShift job has the same gate/API mismatch, and CKASO does not configure hosted kube-apiservers, so an equivalent HyperShift/CPO runtime-config mapping is also needed.

So this is the gate breaking initialization due to missing coordinated API enablement, rather than TechPreview generally being broken.

[JoelSpeed]

Can the KASO PR be merged ahead of this PR, or must they be simultaneously merged?

[harche]

As currently written, the KASO PR cannot safely merge ahead of this one. Its standalone presubmit hits:

feature "DRADeviceTaintRules" is not registered

because the runtime-config mapping calls Enabled() for a gate that does not exist in the current API payload.

I’ve asked for cluster-kube-apiserver-operator#2275 to be updated so an absent/unregistered gate is ignored. With that change, the mapping can and should merge dormant ahead of this PR.

The safe sequence would then be:

1. Merge the tolerant KASO mapping.
2. Merge the equivalent HyperShift/CPO mapping—I’m preparing that PR now.
3. Merge the Origin test expectation update.
4. Merge this API PR last, which activates the gate.

Without the KASO tolerance update, the changes would need coordinated payload testing and effectively atomic promotion; neither current serial order is safe.

[harche]

Now that the HyperShift companion PR is available, here is the consolidated dependency and merge order for this feature.

Prerequisites — may merge in any order

All three must land, or be included in the final payload test, before this API PR activates DRADeviceTaintRules:

1. Self-managed control planes: openshift/cluster-kube-apiserver-operator#2275
   Adds the Kubernetes 1.36 mapping from DRADeviceTaintRules to resource.k8s.io/v1beta2. It first needs to tolerate the gate being unregistered so the mapping can remain dormant before this API PR lands. Details: coordination comment.

2. Hosted control planes: openshift/hypershift#9518
   Adds the equivalent version-aware mapping for hosted kube-apiservers. This mapping is already dormant while the gate is absent or disabled, so it can safely merge before this API PR.

3. Payload test expectation: openshift/origin#31566
   Updates the DRA API-discovery expectation for TPNU. The proposed behavior is to expect resource.k8s.io/v1 and resource.k8s.io/v1beta2 when this gate is enabled on Kubernetes 1.36, while continuing to reject obsolete alpha APIs. Details: coordination comment.

Final validation

After those prerequisites are merged or included in a combined payload, rerun the relevant TechPreview jobs for both self-managed and hosted control planes.

The existing API + CKASO payload run already confirms that the self-managed mapping serves v1beta2, allows the scheduler informer to synchronize, and permits installation to proceed. Its remaining failure is the old Origin assertion.

Activation — merge last

4. Feature-gate registration and activation: openshift/api#3004
   Merge this PR last, because it is the change that activates DRADeviceTaintRules in TPNU.

CKASO #2275 ─────────┐
HyperShift #9518 ────┼──> combined payload validation ──> API #3004 last
Origin #31566 ───────┘

The full failure chain and supporting artifacts are documented in the root-cause analysis. This updates the earlier sequencing comment now that all companion PRs have concrete links.

[JoelSpeed]

because the runtime-config mapping calls Enabled() for a gate that does not exist in the current API payload.

Would adding this gate as disabled in all featuresets help? And then following up to enable it in TP later?

[harche]

Thanks @JoelSpeed, that is a better and cleaner approach than the unregistered gate tolerance I suggested. Hopefully I have the sequence right this time.

Because newFeatureGate(...) defaults to disabled in every feature set unless .enable(...) is specified, we can split registration from activation:

1. Update this PR to register DRADeviceTaintRules as disabled in all feature sets, then merge it.
2. Update cluster-kube-apiserver-operator#2275 to consume the resulting official openshift/api revision, remove the personal fork replacement and vendor coupling, and merge the dormant runtime configuration mapping.
3. Merge the dormant hosted control plane mapping in hypershift#9518.
4. Merge the test expectation update in origin#31566.
5. Follow up in openshift/api to enable DRADeviceTaintRules in TechPreview and DevPreview, validate the combined payload, and merge that activation last.

This supersedes my earlier suggestion that CKASO tolerate an unregistered gate. Thanks for pointing out the cleaner sequencing.

[harche]

@haircommander after you make the change, we might need to update the title for this PR from 'enable' to just 'register'

[haircommander]

thanks all! I should have dug deeper into the failures. updated
