What

Add x-ui-field and x-ui-options XRD vendor extensions that are converted to Backstage ui:field and ui:options in generated scaffolder templates.

When an XRD defines these extensions on spec.owner, the generated Resource Metadata Owner field inherits them as well. This lets each XRD constrain its owner picker independently while retaining the existing Group-only default for XRDs without the extensions.

Why

x-ui-advanced controls visibility only and cannot select a Backstage field extension or configure its catalog filter. Native ui keys are also not Kubernetes vendor extensions. The new x-ui extensions provide a Kubernetes-safe, declarative source of truth in the XRD.

Validation

  • Focused EntityProvider suite: 153 tests passed
  • Kubernetes ingestor lint and type checks passed
  • git diff --check passed

Documentation and an OwnerPicker example are included.

Summary by CodeRabbit

  • New Features

    • Added support for configuring generated Backstage forms with XRD x-ui-field and x-ui-options extensions.
    • Custom form settings now apply to top-level, nested, and array-item fields.
    • Owner picker settings can be customized while retaining sensible defaults when no configuration is provided.
  • Documentation

    • Added guidance and examples for custom XRD form fields, including picker configuration.
    • Added the new documentation page to the Kubernetes Ingestor navigation.

Walkthrough

The Kubernetes ingestor now converts XRD x-ui-field and x-ui-options extensions into Backstage form configuration, including nested schemas and owner fields. Tests cover customization and defaults. Documentation describes the extensions and adds them to navigation.

Changes

XRD form field configuration

Layer / File(s) Summary
Schema UI-extension normalization
plugins/kubernetes-ingestor/src/providers/EntityProvider.ts, plugins/kubernetes-ingestor/src/providers/EntityProvider.test.ts
x-ui-field and x-ui-options become ui:field and ui:options. The source extensions are removed. Recursive processing covers nested objects and array items, with tests for the generated configuration.
Owner fields and validation
plugins/kubernetes-ingestor/src/providers/EntityProvider.ts, plugins/kubernetes-ingestor/src/providers/EntityProvider.test.ts, site/docs/plugins/kubernetes-ingestor/backend/xrd-ui-field-options.md, site/mkdocs.yml
Owner fields inherit XRD UI settings when provided. The default OwnerPicker and Group catalog filter remain when settings are absent. Tests and documentation cover the behavior, and the documentation page is added to navigation.

Custom UI options are ignored for preserved-unknown fields. This is a narrow form-configuration defect that should be fixed before users rely on the new extension there.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve supplied x-ui-options for unknown-field schemas.

When both extensions are present, applyUiExtensions stores x-ui-options in typedValue['ui:options']. The preserved-unknown branch then replaces it with { rows: 10 } before placing the field in the generated Resource Spec parameters.

Merge the textarea default with the existing options, with the supplied values taking precedence.

Proposed fix
             'ui:widget': 'textarea',
             'ui:options': {
               rows: 10,
+              ...typedValue['ui:options'],
             },
