OCPBUGS-114670: fix(capi2mapi): normalize empty SSHKeyName to nil for MAPI AWS conversion

[simkam]

https://redhat.atlassian.net/browse/OCPBUGS-114670

CAPI's AWSMachine.Spec.SSHKeyName is tri-state: nil means "use cluster default", ptr("") means "no SSH key", and a non-empty pointer means a named key. IPI clusters installed with CAPA default to ptr("").

MAPI's AWS actuator has no such tri-state handling — any non-nil KeyName, including an empty string, is passed straight to AWS RunInstances and rejected with "Invalid value '' for keyPairNames".

Normalize ptr("") to nil in the conversion so MAPI omits the field, matching the "no SSH key" intent.

It is equivalent of test helper in openshift/cluster-api-actuator-pkg@6307408#diff-77afc90f80bdb30e5eb1d917d9def6557a9aca2994b361936df2f7f49a41ee39R175

Walkthrough

AWS provider conversion now maps explicitly empty SSH key names to nil. Nil and non-empty key names remain unchanged. Unit and end-to-end tests cover conversion and MachineSet authority switching.

Changes

AWS SSH key normalization

Layer / File(s)	Summary
Normalize and test SSH key names pkg/conversion/capi2mapi/aws.go, pkg/conversion/capi2mapi/machine_test.go	The conversion uses convertAWSSSHKeyNameToMAPI. The helper maps empty key names to nil and preserves nil or non-empty values. Unit tests cover all three inputs.
Validate MachineSet migration e2e/machineset_migration_capi_authoritative_test.go	The end-to-end test uses a CAPI AWSMachineTemplate with an empty SSH key name, switches authority from ClusterAPI to MachineAPI, scales to one replica, and verifies that the MAPI machine reaches Running.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 316c7

This is a localized conversion fix that prevents an empty SSH key name from being sent to AWS while preserving the intended no-key behavior. No actionable merge-blocking risk remains beyond normal checks and review.

Full details: Stable And Deterministic Test Names

Explanation

PASS. The pull request adds only static Ginkgo titles: the context names the fixed scenario "empty SSHKeyName in CAPI template", the example describes the fixed outcome, and the table and entry names are static. Generated resource names are created inside the test body, not in any test title. No added title contains a timestamp, UUID, node or namespace name, IP address, or other run-dependent value.

Full details: Test Structure And Quality

Explanation

The new E2E test has a race after scaling. It calls GetLatestMachineFromMachineSet immediately after ScaleMachineSetWithContext at e2e/machineset_migration_capi_authoritative_test.go:285-290. The helper performs one direct API list and can return (nil, nil) before the controller creates the Machine. The next verifyMachineRunning call then fails on a nil Machine. The sibling migration test waits with mapiframework.WaitForMachineSet(ctx, cl, name) before calling the same helper. Other added assertions and the cleanup hook have useful messages and bounded waits.

Resolution

After scaling, add a bounded wait for the MachineSet to reconcile, such as mapiframework.WaitForMachineSet(ctx, cl, name), before calling GetLatestMachineFromMachineSet. Alternatively, wrap the retrieval in Eventually with an explicit timeout and assert that the returned Machine is non-nil before verifying its Running state.

Full details: Microshift Test Compatibility

Explanation

The added Ginkgo context is not protected from MicroShift and uses unavailable MachineAPI resources. The new test creates and scales CAPI and MAPI MachineSets and verifies a MAPI Machine at lines 188–229. The enclosing test name has no [Skipped:MicroShift] or [apigroup:...] tag, and its only skips check AWS and the MachineAPIMigration feature gate. MicroShift does not provide MachineSet or Machine resources.

Resolution

MicroShift compatibility notice: This test uses APIs or features that are not available on MicroShift. If this repository's presubmit CI does not already include MicroShift jobs, please verify your test works on MicroShift by running an additional CI job: For parallel tests: /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance For serial tests: /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance-serial This test is intentionally API-specific. Add [apigroup:machine.openshift.io] to the enclosing test name, or add [Skipped:MicroShift] to the new context or test name. A runtime exutil.IsMicroShiftCluster() check followed by g.Skip() is also valid.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

The new Ginkgo test is not protected from SNO and tests node addition. It creates the MachineSets with zero replicas, then scales the MAPI MachineSet to one replica and waits for the new machine to reach Running (e2e/machineset_migration_capi_authoritative_test.go:235-291). This matches the check's explicit node-scaling condition. The enclosing suite only skips non-AWS platforms and disabled feature gates.

Resolution

Single Node OpenShift (SNO) compatibility notice: This test assumes a multi-node cluster and may fail on Single Node OpenShift deployments. Please verify the test works on SNO by running an additional CI job: /payload-job periodic-ci-openshift-release-master-ci-4.22-e2e-aws-upgrade-ovn-single-node If the test is not applicable to SNO, add [Skipped:SingleReplicaTopology] to its name or add an exutil.IsSingleNode()/skipOnSingleNodeTopology() guard.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only AWS conversion logic and tests. The exact diff contains no deployment manifests, operator/controller code, pod affinity, topology spread constraints, node selectors/affinity, tolerations, or PDBs. The only replica-related changes are test actions that create or scale MachineSets. The new helper only normalizes SSHKeyName; it does not add scheduling constraints.

Full details: Ote Binary Stdout Contract

Explanation

PASS. The diff changes AWS conversion logic and adds unit/e2e test registration only. No added fmt.Print*, log.Print*, klog output, os.Stdout, or other direct stdout writes appear in the changed files. The e2e setup uses Ginkgo By and test helpers, whose output is framework-intercepted. No main, TestMain, init, BeforeSuite, AfterSuite, SynchronizedBeforeSuite, or RunSpecs setup was changed.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

The added Ginkgo context requires an external AWS API. It creates an AWS template, switches authority, scales the MAPI MachineSet to one replica, and waits for the machine to reach Running. The test comment states that the MAPI actuator calls AWS RunInstances. AWS is outside the cluster, and the test has no disconnected skip marker. The test adds no IPv4-specific address or parsing assumption.

Resolution

IPv6 and disconnected network compatibility notice: This test may contain IPv4 assumptions or external connectivity requirements that will fail in IPv6-only disconnected environments. Please verify your test works on IPv6 by running an additional CI job: /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-ovn-ipv6 If the test is serial, use: /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-serial-ovn-ipv6 If the test cannot run without external AWS connectivity, add [Skipped:Disconnected] to the test name.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request only normalizes an AWS SSH key name pointer and adds unit and end-to-end tests. The changed diff introduces no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB mode, custom cryptography, or secret/token comparisons. The new SSH key handling is configuration conversion, not cryptographic processing.

Full details: Container-Privileges

Explanation

PASS: The pull request changes only three Go files. It adds no YAML, JSON, or other manifest files. No added line contains privileged: true, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation. Privilege-related entries found in the repository are unchanged from the parent revision.

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

Explanation

PASS. The pull request adds no logging calls. Its Ginkgo messages contain only generic test steps, an empty SSH key value, and the non-sensitive test value my-key. The conversion helper only changes KeyName; it does not log credentials, tokens, hostnames, or customer data. The AWS credentials read by existing test helpers are passed to the client and are not written to logs.
