SRVKP-11558: remove deprecated k8s.io/api packages removed in v0.36.0

[anithapriyanatarajan]

k8s.io/api v0.36.0 (Kubernetes 1.36, released Dec 2025) deleted three Go packages that had been deprecated at the server level for years:

k8s.io/api/autoscaling/v2beta1 (deprecated k8s 1.12, server-removed k8s 1.26)
k8s.io/api/autoscaling/v2beta2 (deprecated k8s 1.23, server-removed k8s 1.26)
The upstream removal commit is kubernetes/api@d8ea27e.

k8s.io/api/scheduling/v1alpha1 (deprecated k8s 1.10, server-removed k8s 1.17)

Because Go resolves a single version of k8s.io/api across the entire module graph, any project that depends on both openshift/api and k8s.io/api >= v0.36.0 hits a hard build failure as below

k8s.io/api/autoscaling/v2beta2: module k8s.io/api@v0.36.0 found, but does not contain package k8s.io/api/autoscaling/v2beta2

Example case : Experienced this issue while upgrading k8s.io/client-go to 0.36.0(https://github.com/tektoncd/operator/blob/main/go.mod#L45) to address kubernetes/client-go@ea7a7e7 . We are blocked because of this.

Fixed this by removing the three imports and their AddToScheme registrations from install.go. The stable replacements (autoscaling/v2 and scheduling/v1) were already registered and are unchanged.

Also removes the corresponding vendor directories and modules.txt

📝 Walkthrough

Walkthrough

The change removes three Kubernetes API type packages from the scheme registration in install.go: autoscaling v2beta1, autoscaling v2beta2, and scheduling v1alpha1. The corresponding imports are deleted, and their AddToScheme entries are removed from the kubeSchemeBuilder. The exported scheme installer variables (Install and InstallKube) remain structurally unchanged and continue to register all other OpenShift and Kubernetes API versions.

Check name	Status	Explanation
Description check	✅ Passed	The description clearly explains the reason for the removal, the specific packages affected, the build failure issue it resolves, and how it was fixed.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The PR removes deprecated k8s.io/api packages from install.go. It modifies only infrastructure code (configuration file), not Ginkgo test files. The custom check is not applicable to this PR.
Test Structure And Quality	✅ Passed	This PR removes deprecated k8s.io/api packages from install.go. While test files exist, the PR's primary purpose is not to modify Ginkgo test code. Custom check for test quality is not applicable.
Microshift Test Compatibility	✅ Passed	No new Ginkgo e2e tests were added. The only Ginkgo test (tests/suite_test.go) is a local unit test using envtest.Environment, not an e2e test targeting live clusters.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	No new Ginkgo e2e tests added. This PR removes deprecated k8s.io/api packages. The test files added (tests/suite_test.go and machineconfiguration/install_test.go) are not Ginkgo e2e tests.
Topology-Aware Scheduling Compatibility	✅ Passed	Removes deprecated API imports from library registration. No deployment manifests, operator code, or scheduling constraints added. Check not applicable.
Ote Binary Stdout Contract	✅ Passed	PR removes deprecated k8s.io/api packages. No process-level stdout writes found. Test suite uses proper GinkgoWriter isolation for test stdout.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	No new Ginkgo e2e tests are added in this PR. The PR only removes deprecated k8s.io/api package references from install.go. The check is not applicable.
Title check	✅ Passed	The title clearly and specifically summarizes the main change: removing deprecated k8s.io/api packages that were removed in Kubernetes v0.36.0.

Hello @anithapriyanatarajan! Some important instructions when contributing to openshift/api:
API design plays an important part in the user experience of OpenShift and as such API PRs are subject to a high level of scrutiny to ensure they follow our best practices. If you haven't already done so, please review the OpenShift API Conventions and ensure that your proposed changes are compliant. Following these conventions will help expedite the api review process for your PR.

[openshift-ci]

Hi @anithapriyanatarajan. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
