What

Remove image URL for kmsPlugin.

Why

Plugin images are sourced by the platform: the OLM-managed KMS plugin
provider ConfigMap or the release payload delivers the plugin image
(ref openshift/enhancements#2082). Users must not choose plugin images
themselves, so the field is removed while the API is still TechPreview
behind the KMSEncryption feature gate. The field name is tombstoned in
VaultKMSPluginConfig to reserve it and prevent reuse.

📝 Walkthrough

Walkthrough

The Vault KMS API type no longer defines the configurable KMSPluginImage field. Its image validation was removed, and the field name is reserved in tombstone comments. APIServer CRD schemas no longer expose or require kmsPluginImage. Validation fixtures were updated to remove the field and its dedicated validation cases.

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 1 files.

Full details: Stable And Deterministic Test Names

Explanation

PASS. The PR adds no Ginkgo title constructs and changes no test name: titles. It only removes kmsPluginImage data and its related test cases from YAML fixtures, plus API and generated schema definitions. The remaining Vault KMS test names are static descriptive strings. No changed test title contains a run-dependent value.

Full details: Test Structure And Quality

Explanation

PASS: The PR does not add or modify Ginkgo test code. The two changed test files are declarative API-validation YAML fixtures with onCreate, initial, expected, and expectedError entries, not It blocks or cluster-operation code. The diff removes obsolete kmsPluginImage fixture fields and related cases; it adds no tests, resource creation, waits, or assertions that could violate the listed requirements. The remaining cases use the repository's existing declarative test format.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request adds no Ginkgo e2e tests. The changed test files are YAML fixtures, and their diff only removes existing kmsPluginImage cases and values. The remaining changes update the Go API type and generated schemas. Therefore, the MicroShift test-compatibility conditions do not apply.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

The pull request adds no Ginkgo e2e tests. The changed YAML files are declarative API validation fixtures, and the diff only removes existing kmsPluginImage cases. No multi-node or HA assumption is introduced.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only the Vault KMS API type, validation fixtures, OpenAPI/Swagger output, and CRD schemas. The diff adds or modifies no deployment manifests, operator controllers, workload resources, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. Therefore, the topology-aware scheduling check is not applicable.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The pull request changes only API types, declarative YAML fixtures, and generated schema/OpenAPI files. The only added Go lines are tombstone comments and generated required-field data. No changed process-level code contains stdout writes, klog output, or logging setup changes. The OTE Binary Stdout Contract is therefore not violated.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request adds no Ginkgo e2e tests. Against origin/master, the two modified test fixture files contain only deletions (0 additions; 223 deletions), and the remaining changes are API comments and generated schemas. No changed-line additions introduce IPv4 assumptions or external connectivity requirements.

Full details: No-Weak-Crypto

Explanation

PASS: The cumulative PR diff from 38053d3 to HEAD only removes kmsPluginImage configuration and validation, adds a tombstone comment, and updates generated schemas. No changed line introduces MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto code, or secret comparisons. The retained references use SHA256 only, which is not listed as a failure condition. Existing DES-CBC3-SHA references are outside the PR diff and are pre-existing.

Full details: Container-Privileges

Explanation

PASS. The PR changes API types, test fixtures, generated schemas, and CRD manifests. The diff only removes kmsPluginImage and related validation or adds a tombstone comment. No changed manifest adds privileged: true, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation: true, or root execution settings.

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

Explanation

PASS. The pull request removes the kmsPluginImage field, validation rules, fixtures, and generated schema entries. The only added content is a tombstone comment and regenerated metadata. The diff adds no logging calls, log messages, or sensitive data output. Existing references to secrets, tokens, and hostnames are unchanged schema documentation, not logging.

Align the tombstone with the platform-managed image source.

The tombstone correctly preserves the former validation requirements, but Lines 259-263 still instruct users to obtain, mirror, and reference an image digest through kmsPluginImage. That field no longer exists. Update this text to mark the requirements as historical and document both supported platform sources: the KMS plugin provider ConfigMap and the release payload.

Proposed documentation update
- // Image sourcing has moved to the platform, which resolves the plugin image from the
- // KMS plugin provider ConfigMap rather than from this resource (openshift/enhancements#2082).
+ // Image sourcing is managed by the platform through the KMS plugin provider ConfigMap
+ // or the release payload. This resource does not accept an image reference.
...
- // Consult the OpenShift documentation for compatible plugin versions with your cluster version,
- // then obtain the image digest for that version from HashiCorp's container registry.

+ // The following image requirements are retained as historical documentation only.
+ // Follow the platform documentation for image sourcing in connected and disconnected clusters.
