This PR:

  • Adds the ManagedBootImagesAWSCAPI feature gate
  • Extends the MachineManager enum to include CAPI machinesets & machinedeployments, along with validation rules for interaction with the ManagedBootImagesCPMS features.
  • Adds integration tests for all new feature gate combinations.

Note: We have decided to delay adding validations to the "Automatic" skew enforcement mode until the MCO controller generates the status correctly. This has to be done as a follow-up, as adding all the rules now would break TechPreview clusters.

In response to this:

This PR:

  • Adds the ManagedBootImagesAWSCAPI feature gate
  • Extends the MachineManager enum to include CAPI machinesets & machinedeployments, along with validation rules for interaction with the BootImageSkewEnforcement and ManagedBootImagesCPMS features.
  • Adds integration tests for all new feature gate combinations.

Note: I ran into a issue where the existing integration tests for BootImageSkewEnforcement and ManagedBootImagesCPMS were failing as they were being run against all versions of the MachineConfiguration CRD(including the TechPreview CRD). Since the TechPreview CRD imposes additional rules(requires CAPI resource machinemanagers when in Automatic skew enforcement mode), the old tests were failing - even though they were not including the new feature gate. To fix this, I added-ManagedBootImagesAWSCAPI to the existing tests so they wouldn't be run against the TechPreview version of the CRD. I also added a test file with all three feature gates so no coverage was lost.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the openshift-eng/jira-lifecycle-plugin repository.

📝 Walkthrough

Walkthrough

The change adds and configures feature gates for preview profiles. It extends MachineManager to support Cluster API MachineSets and MachineDeployments with feature-gated API-group validation. The CRD schema documents these values in desired and status configurations. New tests cover valid manager combinations, partial selection behavior, invalid API-group/resource pairs, ControlPlaneMachineSets restrictions, and duplicate managers.

Suggested reviewers: everettraven, joelspeed, vr4manta

Merge Risk: 🟡 Moderate · up to c7a65

The PR adds feature-gate registrations using a builder form that does not follow the required API convention, creating a bounded risk that the new gates will not behave or integrate as intended. Merge should wait for this correction or explicit owner acceptance.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 2 files. (10 skipped: 10 unsupported.)

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request adds static YAML test names only. The names use fixed feature gates, API groups, resource types, and selection modes. They contain no generated suffixes, timestamps, UUIDs, node names, namespaces, IP addresses, or runtime interpolation. The unchanged test generator passes each YAML name directly to Ginkgo Entry(...) and builds suite names from static CRD metadata and feature-gate configuration. The titles describe the validation cases and are not overly specific to run-time values.

Full details: Test Structure And Quality

Explanation

PASS. The PR adds two declarative onCreate suites, not direct Ginkgo code. The 13 cases each target one related MachineManager behavior and use descriptive names plus specific expectedError text. The shared Ginkgo generator provides BeforeEach CRD setup, AfterEach resource and CRD cleanup, and a timed Eventually wait for CRD removal. The added fixtures create only MachineConfiguration objects and contain no pod, deployment, wait, Eventually, or Consistently operations. No new assertion implementation or missing timeout was introduced.

Full details: Microshift Test Compatibility

Explanation

The pull request adds 13 Ginkgo-generated cases in two YAML suites. tests/suite_test.go loads these suites, and tests/generator.go generates Describe and DescribeTable nodes from them. The cases create operator.openshift.io/v1 MachineConfiguration objects and include machine.openshift.io MachineSets. MicroShift does not serve these APIs or resources. No new case contains [Skipped:MicroShift] or [apigroup:...], and the generated enclosing descriptions do not add either protection marker.

Resolution

MicroShift compatibility notice: These tests use APIs or features that are not available on MicroShift. If this repository's presubmit CI does not already include MicroShift jobs, verify the tests with /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance or, for serial tests, /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance-serial. Because these are API-specific tests, add an [apigroup:operator.openshift.io] tag to the generated test name or enclosing Describe so MicroShift CI skips the suites. A [Skipped:MicroShift] label or an exutil.IsMicroShiftCluster() guard is an alternative.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request adds two YAML-based MachineConfiguration API validation suites under operator/v1/tests, using onCreate, initial, expected, and expectedError entries. The base-to-HEAD diff adds no Ginkgo test files, Ginkgo imports, or It/Describe/Context/When calls. The tests do not assume node counts, scheduling, affinity, failover, draining, scaling, or multiple endpoints. SNO compatibility checks are therefore not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request adds API types, feature-gate metadata, CRD schemas, feature-gate manifests, and MachineConfiguration validation tests. The source diff contains no deployment/controller changes and no scheduling constraints such as affinity, topology spread, replica sizing, node selectors, tolerations, or PDBs. The new MachineDeployments value refers to a Cluster API machine-management resource, not a workload deployment. Therefore, the check's topology-aware scheduling failure conditions are not introduced.

Full details: Ote Binary Stdout Contract

Explanation

No OTE stdout violation was introduced. The PR changes four Go files, and the diff contains no main, TestMain, Ginkgo suite setup, fmt.Print*, log.Print*, klog output, or os.Stdout writes. The new top-level feature-gate initializer only calls builder methods; those helpers register data and do not write output. The remaining changes are API declarations, generated documentation, manifests, and declarative YAML tests.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS. The pull request adds two declarative API-validation test suites, not direct Ginkgo e2e network tests. The cases create MachineConfiguration objects and check defaults or validation errors. They contain no IPv4 addresses, IP parsing, URLs used for connections, image pulls, DNS lookups, or external service calls. The test documentation confirms these suites run against a temporary envtest API server.

Full details: No-Weak-Crypto

Explanation

No weak-crypto issue was introduced. The merge-base diff adds feature-gate metadata, MachineManager enum and validation declarations, generated schemas, manifests, and integration-test YAML. An exact scan of added lines found no MD5, SHA-1, DES, RC4, 3DES, Blowfish, or ECB usage. The changed Go files add no crypto imports, cryptographic calls, custom crypto, or secret/token comparisons.

Full details: Container-Privileges

Explanation

No changed container or Kubernetes workload manifest introduces a flagged privilege setting. The pull request adds MachineConfiguration test/CRD schemas and feature-gate entries. Diff searches found no added privileged: true, hostPID, hostNetwork, hostIPC, SYS_ADMIN, root execution, or allowPrivilegeEscalation: true configuration.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS. The PR adds feature-gate declarations, validation metadata, generated schemas, manifests, and test YAML. The diff adds no logging calls or formatted log output. The added logLevel and operatorLogLevel values are configuration fields set to Normal, not sensitive data. No added passwords, tokens, API keys, PII, session IDs, hostnames, or customer data were found.

Regenerate the CRD enum schema for the CAPI values.

The descriptions now allow cluster.x-k8s.io and machinedeployments, but the adjacent enums still allow only machine.openshift.io, machinesets, and controlplanemachinesets. The API server will reject CAPI MachineManagers before the feature-gated validation rules can apply. Regenerate this CRD from operator/v1/types_machineconfiguration.go so both schema locations contain the feature-gate-aware CAPI enum expansion.

I am concerned that these rules will break existing TechPreview clusters, which will deploy in Automatic mode for most cases we have in CI. What would be the best order of operations here? Leave these rules out for now and add them in a follow-up PR, once the MCO controller properly generates the status with CAPI resources in TechPreview mode?

Using claude to break down the validations a bit:

The two status rules reads: if Automatic mode AND status.managedBootImagesStatus.machineManagers is populated, the list must contain an (All, machinesets, cluster.x-k8s.io) entry (line 26) and an (All, machinedeployments, cluster.x-k8s.io) entry (line 27). Combined with the pre-existing MAPI status rule (line 23), any Automatic-mode cluster with a populated status is now forced to simultaneously contain MAPI-machinesets and CAPI-machinesets and
CAPI-machinedeployments "All" entries.

Since the MCO controller doesn't yet emit CAPI entries into status, every existing TechPreview cluster's status write will be rejected. Worse, even a pure-MAPI cluster with no CAPI resources at all would be forced to publish CAPI status entries — which is never satisfiable.

So I think you're right and we would need to drop this until generates the necessary status's

I've made an update that does just this :)

Worse, even a pure-MAPI cluster with no CAPI resources at all would be forced to publish CAPI status entries — which is never satisfiable

This statement is a little strange, because presence of the CAPI managers in the status does not depend on the CAPI resources actually existing in the cluster. I'll chalk it to up to AI hallucinating 😄

A suggestion from claude: add additional validation for invalid resource and apiGroup combos, something like:

  + // +openshift:validation:FeatureGateAwareXValidation:requiredFeatureGate=ManagedBootImagesAWSCAPI,rule="self.resource == 'machinedeployments' ? self.apiGroup == 
  'cluster.x-k8s.io' : true",message="the machinedeployments resource is only supported in the cluster.x-k8s.io API group"

  'machine.openshift.io' : true",message="the controlplanemachinesets resource is only supported in the machine.openshift.io API group"

I suppose it's possible someone misconfigures this, but presumably something in the MCO controllers would have caught the invalid combination?

Using claude to break down the validations a bit:

The two status rules reads: if Automatic mode AND status.managedBootImagesStatus.machineManagers is populated, the list must contain an (All, machinesets, cluster.x-k8s.io) entry (line 26) and an (All, machinedeployments, cluster.x-k8s.io) entry (line 27). Combined with the pre-existing MAPI status rule (line 23), any Automatic-mode cluster with a populated status is now forced to simultaneously contain MAPI-machinesets and CAPI-machinesets and
CAPI-machinedeployments "All" entries.

Since the MCO controller doesn't yet emit CAPI entries into status, every existing TechPreview cluster's status write will be rejected. Worse, even a pure-MAPI cluster with no CAPI resources at all would be forced to publish CAPI status entries — which is never satisfiable.

So I think you're right and we would need to drop this until generates the necessary status's

Use enableIn(...) for the new feature gates.

FeatureGateManagedBootImagesAWSCAPI, FeatureGateIngressControllerLBSecurityGroupsAWS, and FeatureGateGomaxprocsInjection use .enable(...). Replace these calls with the required .enableIn(...) builder form. The upstream OpenShift API guidance uses this form for new feature-gate registrations. (github.com)

As per coding guidelines, new FeatureGates in features/features.go must use newFeatureGate(...).reportProblemsToJiraComponent(...).contactPerson(...).productScope(...).enableIn(...).mustRegister().
