OPNET-595: Promote BGPBasedVIPManagement to TechPreviewNoUpgrade - #3165
Enable BGPBasedVIPManagement in TechPreviewNoUpgrade in addition to DevPreviewNoUpgrade. The gate remains disabled in Default and OKD.
The manual source changes are the enable(...) line in features/features.go and the CRD filename constants/list in config/v1/types_infrastructure_test.go. The rest of the feature builder, including its ownership and enhancement metadata, is unchanged. TestInfrastructureStatusDefault retains its Default check and applies the unchanged loop and assertions to both generated TechPreview profile CRDs. All other changes are generated with the repository's full make update targets:
features.md and the TechPreviewNoUpgrade payload feature-gate manifests.
The payload and zz_generated BGPVIPConfig CRDs gain TechPreviewNoUpgrade in their feature-set annotation.
TechPreviewNoUpgrade Infrastructure CRDs gain status.platformStatus.baremetal.vipManagement.
TechPreviewNoUpgrade ControllerConfig CRDs gain the gated vipManagement and bgpVIPPeersJSON fields.
The generator splits the TechPreviewNoUpgrade Infrastructure and ControllerConfig variants into per-profile files because their schema-equivalence grouping changes. The profile pairs differ only in profile annotation; there are no Default/OKD manifest changes or unrelated schema changes. Generated files were not hand-edited.
This PR does not claim every graduation criterion is complete. E2E tests carrying [OCPFeatureGate:BGPBasedVIPManagement] are being written in openshift/origin; the proposal's minimum-five-tagged-tests and seven-runs-per-week criteria remain pending. This PR also does not establish completion of the proposal's dual-stack, documentation, metrics/alerts or NodeDisruptionPolicy criteria.
API migration and payload evidence
The structured BGPVIPConfig API and consumer migration have merged:
These changes are in Accepted 5.1 nightlies starting with 5.1.0-0.nightly-2026-11-07-070556. The daily base e2e-metal-ipi-bgp-vip periodic is green on those payloads:
This evidence is for the base BGP VIP lane, not a claim that every coexistence lane or the pending tagged-test criteria pass.
Impact on TechPreviewNoUpgrade clusters
BGP VIP management is bare-metal-only and inert unless platform.baremetal.bgpVIPConfig is set. Without that configuration the installer emits no BGPVIPConfig CR or peer-password Secrets and leaves vipManagement unset.
MCO creates the feature-gated BGPVIPConfig informer but starts it only on BareMetal, and acts only with BGP VIP management selected.
CNO registers the feature-gated BGPVIPConfig watch but renders BGP configuration only for BareMetal with vipManagement: BGP.
Other TechPreviewNoUpgrade clusters receive the CRD and CNO watch; MCO's informer is not started there, and no BGP configuration is rendered.
Promotion verifier
verify-feature-promotion checks gates newly enabled in Default. This TechPreviewNoUpgrade-only promotion does not enter that check; the tagged origin tests remain ongoing work, not evidence supplied by this PR.
Validation
The full local unit suite, aggregate verification and feature tests passed on signed head 28708b802fbbb9d6e864938a1d2bab1bfee3643e:
make test-unit JUNITFILE=/workspace/validation-28708b8/junit_report.xml --warn-undefined-variables
GOFLAGS=-count=1 make test-unit JUNITFILE=/workspace/validation-28708b8/junit_report.xml --warn-undefined-variables
make verify PULL_BASE_SHA=248dd91956cec586fd277b02f58a745d1ed292e4
go test ./features/... -count=1
Both full unit runs completed successfully (nine packages, no failures), including TestInfrastructureStatusDefault. All ten aggregate verification stages completed successfully, including golangci-lint with 0 issues. Formatting, incremental-diff and unchanged-assertion checks passed; the signed working tree is clean.
The original generated change used full make update, run twice because CRD generation reads the feature-gate manifests refreshed later in the target. Generation is stable. The follow-up commit changes only the infrastructure test's filename constants/list; it changes no schema or generated artifact.
The separately invoked verify-crd-schema check still needs a maintainer disposition for the existing IBM Cloud CEL violations exposed by the generated per-profile filenames, as documented in the PR discussion. This test-only repair does not alter schemas, bounds, authentication, check policy or the other outstanding API/security review concerns.

Walkthrough
The change adds TechPreviewNoUpgrade to the enabled feature sets for BGPBasedVIPManagement. It updates the feature declaration, CRD annotation, feature table, and HyperShift and SelfManagedHA feature-gate manifests. The manifests move the feature from the disabled list to the enabled list. The infrastructure status-default test now discovers matching infrastructure CRD manifests and checks each one.

Merge Risk: Moderate · up to 64af0
This promotes BGP-based VIP management to Tech Preview. Two open issues should be addressed or explicitly accepted before merge. Peer passwords may be written into a readable FRRConfiguration object. A large but valid peer configuration can exceed the transport size limit and fail to apply. The impact is limited to Tech Preview bare-metal clusters that opt in.

Full details: Title check
Explanation
The title names the main change: promoting the BGPBasedVIPManagement feature gate from DevPreviewNoUpgrade to TechPreviewNoUpgrade. The changeset enables the gate in features/features.go and updates the TechPreviewNoUpgrade feature-gate manifests, CRDs, and tests. The OPNET-595 Jira key is extra context and does not hurt clarity.
Full details: Description check
Explanation
The description states that the PR enables BGPBasedVIPManagement in TechPreviewNoUpgrade, lists the manual source changes, and explains the generated manifests, CRDs, and test changes. It also covers enhancement criteria, payload evidence, and validation runs. It is directly related to the changeset.
Full details: Stable And Deterministic Test Names
Explanation
The check applies to Ginkgo test titles (It, Describe, Context, When and similar). The reviewed range changes 13 files: Go changes are limited to features/features.go (one enable(...) line that adds TechPreviewNoUpgrade to BGPBasedVIPManagement) and config/v1/types_infrastructure_test.go (a plain Go testing test, TestInfrastructureStatusDefault, with a glob over generated CRD filenames). Scanning all added lines in the .go diff found no added It/Describe/Context/When/DescribeTable/Entry calls, so no test title is introduced or modified. The remaining changes are YAML/Markdown manifests and generated CRDs. The PR does not add or change any Ginkgo test title, so no dynamic or legacy-metadata title content is present. Repository-wide titles are outside the PR's changes and cannot cause a FAIL. Note: the PR's own references to pending origin E2E tests are not in this diff, so they cannot be assessed here.
Full details: Test Structure And Quality
Explanation
The check applies to Ginkgo test code. The PR changes one test file, config/v1/types_infrastructure_test.go. That file uses the standard Go testing package with TestInfrastructureStatusDefault. A search of the file found no Ginkgo constructs (g.It, It(, Describe(, BeforeEach, AfterEach, Eventually, Consistently). No other changed file is a test file. The test diff only swaps the hard-coded CRD filenames for a filepath.Glob over zz_generated.crd-manifests, adds explicit t.Fatalf guards, and keeps the existing assertions. No new It() block was added, so the informing recommendation (item 6) does not apply. The remaining changes are generated feature-gate manifests, CRDs, and features.md. Those files are outside the scope of this Ginkgo-focused check. The check is inapplicable, so it passes.
Full details: Microshift Test Compatibility
Explanation
The check applies only when new Ginkgo e2e tests (It, Describe, Context, When, and similar) are added. The changed-file inventory for refs/coderabbit/pre-merge-check/base..head shows no new Ginkgo e2e test files. The only test-file change is config/v1/types_infrastructure_test.go. It is a standard Go unit test (TestInfrastructureStatusDefault(t *testing.T)). It globs the generated infrastructure CRD manifests and checks status defaults. A search of the added lines found no It(, Describe(, Context(, When(, g.It(, g.Describe(, apigroup, or Skipped:MicroShift tokens. The other changes are feature-gate manifests, features.go, features.md, and CRD YAML files. None of them adds an e2e test. The check is therefore inapplicable, and it passes.
Full details: Single Node Openshift (Sno) Test Compatibility
Explanation
The check applies only when new Ginkgo e2e tests (It, Describe, Context, When) are added. The diff inventory (git diff --name-status over the review range) shows no new Ginkgo e2e test files. The only Go test file touched is config/v1/types_infrastructure_test.go. It is a standard Go unit test that changes filename constants and a glob loop for TestInfrastructureStatusDefault. A search of added diff lines for Ginkgo constructs found only etcd documentation URLs inside generated CRD descriptions. Everything else is feature-gate, CRD, and features.md generated content. Because no new Ginkgo e2e tests were introduced, the SNO compatibility check does not apply. The PR's stated pending origin e2e tests are not in this PR and cannot be assessed here.
Full details: Topology-Aware Scheduling Compatibility
Explanation
The check applies to added or modified deployment manifests, operator code, or controllers that introduce scheduling constraints. This PR changes none of those in a way that adds scheduling constraints. The changed files are: - Feature-gate definitions: features/features.go, features.md, and the TechPreviewNoUpgrade feature-gate payload manifests. These move BGPBasedVIPManagement from DevPreviewNoUpgrade to TechPreviewNoUpgrade. - CRD manifests: the BGPVIPConfig CRD annotation, plus per-profile Infrastructure and ControllerConfig CRDs. These are generated schema files. - config/v1/types_infrastructure_test.go: the test now checks the generated TechPreview profile CRDs. I searched the added lines for scheduling terms: affinity, toleration, nodeSelector, topology spread, maxUnavailable, PodDisruptionBudget, control-plane and node-role labels, replicas, and arbiter. The only hits were: - vSphere zoneAffinity and regionAffinity schema fields. These describe failure domains and are not pod scheduling constraints. - The controlPlaneTopology enum and its description, including HighlyAvailableArbiter. This is existing API schema text copied into the split per-profile CRD files. It is not new scheduling logic. No Deployment, DaemonSet, StatefulSet, pod spec, or controller code with anti-affinity, spread constraints, control-plane nodeSelectors, or PDBs is added or modified. The PR does not change the topology-specific scheduling behavior that the check guards. The PR description also cites installer, MCO, and CNO behavior as context. Those repositories are outside this checkout, so I did not inspect them. That does not change the outcome, because this PR's own diff adds no scheduling constraint.
Full details: Ote Binary Stdout Contract
Explanation
The check is inapplicable to this pull request, so it passes. - The check covers OpenShift Tests Extension (OTE) binaries and process-level stdout in main(), init(), TestMain(), suite setup, or top-level initializers. - This PR is in openshift/api, which holds API type definitions, feature-gate definitions, generated CRDs and feature-gate manifests. It does not build an OTE test binary. - The PR range changes 2 Go files: features/features.go (one enable(...) line for BGPBasedVIPManagement) and config/v1/types_infrastructure_test.go (a test function that reads CRD manifests). Neither adds main, init, TestMain, fmt.Print*, os.Stdout, klog, log.SetOutput, or BeforeSuite code. - The remaining changes are YAML manifests, CRDs and features.md. None of them produce process stdout. - The repository contains main() functions, such as payload-command/cmd/render/main.go and tools/publish-kubebuilder-tools/main.go. None of them is changed by this PR, so no stdout behavior in them is introduced.
Full details: Ipv6 And Disconnected Network Test Compatibility
Explanation
The check applies only when new Ginkgo e2e tests (It, Describe, Context, When, etc.) are added. The changed-file inventory for refs/coderabbit/pre-merge-check/base..head contains no e2e test files. The only test file changed is config/v1/types_infrastructure_test.go, which is a standard Go unit test (TestInfrastructureStatusDefault) that reads generated CRD manifests from disk. A search of all changed files for Ginkgo markers (ginkgo, g.It(, It(, o.Expect) returned no matches. The remaining changes are feature-gate definitions (features/features.go, features.md), payload and zz_generated CRD manifests, and feature-gate manifests. None adds IPv4-specific network assumptions or external connectivity in an e2e test. The check is inapplicable, so it passes. The PR description's unresolved concerns (tagged origin e2e tests still pending, verify-crd-schema, and API/security review) are outside this check's scope. Future origin e2e tests tagged for BGPBasedVIPManagement would need their own review under this check.
Full details: No-Weak-Crypto
Explanation
The no-weak-crypto check finds no weak-crypto usage, custom crypto code, or non-constant-time secret comparison introduced by this PR. Evidence: - The PR changes 2 Go files. In features/features.go, one line changes from enable(inDevPreviewNoUpgrade()) to enable(inTechPreviewNoUpgrade(), inDevPreviewNoUpgrade()). In config/v1/types_infrastructure_test.go, the test switches to a glob over generated infrastructure CRDs and keeps the same status-default assertions. Neither file adds crypto, hashing, cipher, or comparison code. - The other changes are generated YAML: feature-gate manifests, CRD annotations, and per-profile CRDs. A search of all added diff lines for md5, sha1, DES, 3DES, RC4, Blowfish, ECB, cipher, HMAC, and constant-time comparison terms found no crypto usage. The only hits were IAM API URLs (iam-identity-token-api) and pull-secret field descriptions. - The PR description mentions TCP MD5 BGP authentication. That mechanism is pre-existing and is handled by the network stack (FRR/CNO), not by code in this diff. The PR's text states it does not change that transport or its bounds. The PR only makes the gate available in TechPreviewNoUpgrade. The check's failure conditions target weak crypto used in code or introduced by the change, so this protocol-level context does not match a failure condition. It is noted here for reviewers and is not a finding under this check.
Full details: Container-Privileges
Explanation
The container-privileges check looks for privileged containers, host namespace sharing (hostPID, hostNetwork, hostIPC), SYS_ADMIN, root execution without justification, and allowPrivilegeEscalation: true in container or Kubernetes manifests. Evidence: - The diff changes only feature-gate code and manifests (features/features.go, features.md, payload-manifests/featuregates/*), CRD schemas (BGPVIPConfig, Infrastructure, ControllerConfig), and config/v1/types_infrastructure_test.go. The diff contains no Pod, Deployment, DaemonSet, or other workload manifest. - A grep of all added lines for privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, runAsUser, runAsNonRoot, capabilities, securityContext, and root returned only CRD schema field names (rootCAData). None of these sets a privilege setting. - The new and renamed Infrastructure and ControllerConfig files are CRD schemas, not container specs. They add API fields (vipManagement, bgpVIPPeersJSON, baremetal.vipManagement), not container security settings. No explicit failure condition from the check is introduced by this PR. The unresolved API and security review items in the PR discussion (transport size, TCP MD5 password transport, RBAC) are outside this check's criteria.
Full details: No-Sensitive-Data-In-Logs
Explanation
The check looks for logging that could expose passwords, tokens, API keys, PII, session IDs, internal hostnames, or customer data. I inspected the PR's committed diff (base refs/coderabbit/pre-merge-check/base to head). - Go source changes are limited to features/features.go, which changes one enable(...) call to add inTechPreviewNoUpgrade(), and config/v1/types_infrastructure_test.go. - In the test file, the only added log-like calls are t.Fatalf messages. They print CRD manifest file paths and an error value from file I/O or globbing. They do not print credential, PII, or customer data. - A search of added Go lines for log., klog, logr, slog, zap, fmt.Print*, and t.Log* found no other logging calls. - Lines in the generated YAML that mention passwords, tokens, or secrets (for example pullSecret, internalRegistryPullSecret, and IBM IAM token URLs) are existing CRD schema description text, not logging statements. The PR does not add runtime logging of them. - The PR-described BGP peer-password transport and the bgpVIPPeersJSON field appear only as generated schema. The diff contains no code that logs them. No failure condition in the custom check is met.

Align the host override limit with the MCO transport limit.
This CRD permits 256 host overrides with 16 peers each. A valid configuration with 256 overrides and eight peers per override exceeds the 65,536-character limit on ControllerConfig.spec.bgpVIPPeersJSON. MCO serializes all overrides into that field, so the API rejects the ControllerConfig update and MCO cannot apply the peer changes. Align the CRD bounds and transport capacity before exposing this schema in Tech Preview. (raw.githubusercontent.com)

Investigated on unchanged head 44b228145fa258f1146c5a169601dbad74ba9486 against base 248dd91956cec586fd277b02f58a745d1ed292e4.
Schema check: the generated per-profile TechPreview filenames expose an existing IBM Cloud serviceEndpoints[].url CEL cost-budget violation. The checker ratchets against the same file path at the base; the newly split paths have no baseline. Completed reproductions using make verify-crd-schema PULL_BASE_SHA=248dd91956cec586fd277b02f58a745d1ed292e4:
PR head: fails with the CI errors.
Unmodified base: passes.
Base schemas copied to the new per-profile filenames, with no BGP fields added: fails with the same errors.
The failing IBM schema blocks are identical in base and PR. This is a real check failure triggered by the generated path split, not a new IBM schema defect or an infrastructure failure. Local make verify passed because its aggregate codegen verifier excludes the separately invoked schema checker. Resolving the existing IBM schema or changing baseline matching is outside this promotion's one-source-line-plus-generated-output scope; an authorized maintainer needs to decide the check's disposition.
Transport-size review: confirmed the existing mismatch. A synthetic serialization using the MCO transport structs with 256 host overrides and eight minimal IPv4 peers per override produced 95,278 bytes, above ControllerConfig.spec.bgpVIPPeersJSON's 65,536-character bound. The measured JSON is ASCII. These bounds and transport predate this PR; choosing tighter API limits, a size guard or a transport change needs an API-reviewer decision before expanding this PR's scope.
TCP MD5 review: inspecting the existing consumers confirms passwordSecret is used for TCP MD5 BGP authentication, including the FRR neighbor-password rendering. The existing internal transport also contains the resolved password. This promotion changes neither behavior; I am not marking the security concern resolved. Any authentication or transport redesign needs an explicit security/API decision.
No code changes, push, retest or override were performed. The separate unit-check failure that appeared during this investigation is not yet classified.
The newly failed unit check is now identified: TestInfrastructureStatusDefault in config/v1/types_infrastructure_test.go hard-codes 0000_10_config-operator_01_infrastructures-TechPreviewNoUpgrade.crd.yaml. The generator replaced that combined file with the Hypershift and SelfManagedHA TechPreview variants, so the test fails while reading the removed path, before its status-default assertion.
This failure is caused by the generated file split, unlike the pre-existing IBM schema violation discussed above. The minimal repair is to keep the Default check and run the same status-default assertions against both generated TechPreview profile files. That requires a handwritten test change beyond the explicitly requested one feature-enable line plus generated output. I have requested scope confirmation before making it; no assertion will be removed or relaxed.
Pushed the unit-test filename repair in 28708b802fbbb9d6e864938a1d2bab1bfee3643e. The follow-up changes only config/v1/types_infrastructure_test.go: keep the Default path and check both generated Hypershift/SelfManagedHA TechPreview paths, with the loop and assertions unchanged.
Validation completed successfully: the full CI make test-unit command and an uncached rerun, all make verify stages against base 248dd91956cec586fd277b02f58a745d1ed292e4, and uncached go test ./features/.... The description now reflects the additional test-only source change and validated head.
This resolves the missing-filename unit-test regression locally; the new PR CI results are separate. No schema, bounds, authentication or check-policy changes were made. The previously documented schema-check disposition and API/security decisions remain open; no override or retest was issued.

Protect the password before enabling this feature in TechPreview.
When a BGP peer uses passwordSecret, MCO places the resolved password in ControllerConfig.spec.bgpVIPPeersJSON. A cluster-reader user can read that password without access to the source Secret. Use a Secret-protected transport that still delivers the password to the nodes before promoting the feature.

Keep peer passwords out of FRRConfiguration.
When a default peer uses passwordSecret, CNO writes its password into the bgp-vip FRRConfiguration. FRRConfiguration readers, including node-bootstrapper, can retrieve the password even when they cannot read the source Secret. Protect this copy before promotion; protecting the MCO transport alone does not protect it.

Match the split CRDs to their combined baselines.
The checker treats both Infrastructure and ControllerConfig profile paths as new. It reports the existing IBM Cloud URL cost error and fails the schema job. Match each profile to its former combined schema so the check can still detect new violations.

Follow-up on the latest review and CI for 28708b802fbbb9d6e864938a1d2bab1bfee3643e:
Unit CI now passes, confirming the filename repair in the actual presubmit.
The new verify-crd-schema run again reports the missing combined-schema baselines and the same IBM Cloud serviceEndpoints[].url CEL cost-budget errors. The earlier base/renamed-base reproduction still applies; the follow-up changed only the test paths.
The new request to change baseline matching is outside the explicitly approved test-only repair and the restriction against check-policy changes. No mapping change, override or retest was made.
The password-transport findings remain open. The public CNO template bindata/network/frr-k8s/003-static-pod-rbac.yaml confirms a ClusterRole granting get/list/watch of FRRConfiguration and binding it to the MCO node-bootstrapper service account when BGP VIP management is enabled. The earlier consumer inspection confirmed the resolved password copies in ControllerConfig and FRRConfiguration. I have not independently validated the new review's specific cluster-reader authorization claim or a deployed cluster's effective permissions, and I am not marking the security review resolved.
Changing either consumer's secret transport, API bounds, or schema-check policy requires an explicit maintainer/API/security decision beyond this test-only repair. No such changes were made.

The enhancement in openshift/enhancements#1982 is still open, and we expect it to merge before a gate moves into TechPreviewNoUpgrade. Its Tech Preview criteria such as the tagged origin tests are also still open. Can we hold this until both are done?

MCO writes the plaintext peer passwords into this field, and cluster-reader can read ControllerConfig. That exposes the passwords without access to the Secrets. Can MCO move them to a Secret-backed transport before this goes to Tech Preview?

BGPVIPConfig accepts more hostOverrides and peers than fit in this field. When that happens, the whole ControllerConfig update fails after admission. Can we align the BGPVIPConfig bounds with this limit so the API rejects it up front?
The reason will be displayed to describe this comment to others. Learn more.
Yes and no. It's not a trivial math. You have 64K limit on the CR size. You can consume this limit with gazillion of small host overrides or a handful of monstrous ones.
I am happy to implement a suggestion but I don't have an idea. Just setting the limit to something conservatively small like 5 is defeating the purpose.
Enable the BGPBasedVIPManagement feature gate in the TechPreviewNoUpgrade
feature set in addition to DevPreviewNoUpgrade. The gate stays disabled
in the Default and OKD feature sets.
The only manual change is the enable() call in features/features.go;
everything else is output of `make update`:
- The TechPreviewNoUpgrade payload feature gate manifests and
features.md list the gate as enabled.
- bgpvipconfigs.machineconfiguration.openshift.io now carries
release.openshift.io/feature-set:
CustomNoUpgrade,DevPreviewNoUpgrade,TechPreviewNoUpgrade.
- The TechPreviewNoUpgrade infrastructures.config.openshift.io CRD gains
the gated status.platformStatus.baremetal.vipManagement field and the
TechPreviewNoUpgrade controllerconfigs.machineconfiguration.openshift.io
CRD gains vipManagement and spec.bgpVIPPeersJSON.
- With the gate enabled, the Hypershift TechPreviewNoUpgrade schema of
these two CRDs is identical to its DevPreviewNoUpgrade schema, so the
CRD generator now writes per-cluster-profile TechPreviewNoUpgrade files
instead of a single combined file. This reverses the merge the
generator made when the gate was introduced as DevPreviewNoUpgrade-only.
Enhancement: openshift/enhancements#1982
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Promoting BGPBasedVIPManagement to TechPreviewNoUpgrade makes the CRD
generator write separate Hypershift and SelfManagedHA
TechPreviewNoUpgrade infrastructure CRDs instead of one combined file,
so TestInfrastructureStatusDefault could no longer open the combined
file.
Glob the generated infrastructure CRDs instead of hardcoding profile
file names, so the test keeps working when the profile split changes
again. The existing per-file assertions are unchanged. The test now
covers every generated infrastructure CRD variant and fails if no CRD
matches or the Default CRD is missing.

enable(...)line infeatures/features.goand the CRD filename constants/list inconfig/v1/types_infrastructure_test.go. The rest of the feature builder, including its ownership and enhancement metadata, is unchanged.TestInfrastructureStatusDefaultretains its Default check and applies the unchanged loop and assertions to both generated TechPreview profile CRDs. All other changes are generated with the repository's fullmake updatetargets:features.mdand the TechPreviewNoUpgrade payload feature-gate manifests.zz_generatedBGPVIPConfig CRDs gainTechPreviewNoUpgradein their feature-set annotation.status.platformStatus.baremetal.vipManagement.vipManagementandbgpVIPPeersJSONfields.The generator splits the TechPreviewNoUpgrade Infrastructure and ControllerConfig variants into per-profile files because their schema-equivalence grouping changes. The profile pairs differ only in profile annotation; there are no Default/OKD manifest changes or unrelated schema changes. Generated files were not hand-edited.
Enhancement criteria and remaining work
This implements the gate-promotion part of the Dev Preview -> Tech Preview criteria in enhancement #1982, which remains open.
This PR does not claim every graduation criterion is complete. E2E tests carrying
[OCPFeatureGate:BGPBasedVIPManagement]are being written inopenshift/origin; the proposal's minimum-five-tagged-tests and seven-runs-per-week criteria remain pending. This PR also does not establish completion of the proposal's dual-stack, documentation, metrics/alerts or NodeDisruptionPolicy criteria.API migration and payload evidence
The structured
BGPVIPConfigAPI and consumer migration have merged:These changes are in Accepted 5.1 nightlies starting with
5.1.0-0.nightly-2026-11-07-070556. The daily basee2e-metal-ipi-bgp-vipperiodic is green on those payloads:This evidence is for the base BGP VIP lane, not a claim that every coexistence lane or the pending tagged-test criteria pass.
Impact on TechPreviewNoUpgrade clusters
BGP VIP management is bare-metal-only and inert unless
platform.baremetal.bgpVIPConfigis set. Without that configuration the installer emits no BGPVIPConfig CR or peer-password Secrets and leavesvipManagementunset.vipManagement: BGP.Other TechPreviewNoUpgrade clusters receive the CRD and CNO watch; MCO's informer is not started there, and no BGP configuration is rendered.

make update, run twice because CRD generation reads the feature-gate manifests refreshed later in the target. Generation is stable. The follow-up commit changes only the infrastructure test's filename constants/list; it changes no schema or generated artifact.The separately invoked
verify-crd-schemacheck still needs a maintainer disposition for the existing IBM Cloud CEL violations exposed by the generated per-profile filenames, as documented in the PR discussion. This test-only repair does not alter schemas, bounds, authentication, check policy or the other outstanding API/security review concerns.AI-generated. Review for accuracy.
