Proposed Changes

  • SettingsFlow (list of named, prioritized setting groups) replacing the flat SettingsMap on BMCSettings/BIOSSettings
  • BMCSettingsRefs/BIOSSettingsRefs (slice) replacing the single BMCSettingRef/BIOSSettingsRef on BMC/Server
  • DriftPolicy field (Observe/Suspend) added to BMCSettings and BIOSSettings
  • Controller migration logic (deprecated field → new field, fall-through behavior for ref patching)
  • Webhook duplicate check now requires both ServerRef/BMCRef AND Version to match due to spec changes
  • Test updates throughout

Fixes #944
Fixes #814

Summary by CodeRabbit

  • New Features
    • Added driftPolicy (enum Observe/Suspend) to BIOS/BMC settings and versions.
    • Added multi-reference support: biosSettingsRefs on Servers and bmcSettingsRefs on BMCs.
    • Introduced settingsFlow for BMC settings as the priority-ordered replacement for flat settings.
  • Deprecations
    • Deprecated single reference fields (biosSettingsRef, bmcSettingsRef) in favor of the new lists.
    • Deprecated flat settings in favor of settingsFlow.
  • Validation & Behavior
    • Tightened CRD/webhook validation (required fields, settings vs settingsFlow exclusivity, duplicate checks) and automatic migration from deprecated fields.

📝 Walkthrough

Walkthrough

Introduces a DriftPolicy enum (Observe/Suspend) across BIOS and BMC Settings/Version specs. Migrates single settings-reference fields (BMCSettingRef, BIOSSettingsRef) to list fields and replaces flat SettingsMap with priority-ordered SettingsFlow. Controllers, webhooks, CRD schemas, and apply-configuration code are updated accordingly, with backward-compatible migration on first reconcile.

Changes

DriftPolicy, SettingsFlow, and Multi-Ref Migration

Layer / File(s) Summary
API types: DriftPolicy, SettingsFlow, multi-ref fields, and deepcopy
api/v1alpha1/common_types.go, api/v1alpha1/biossettings_types.go, api/v1alpha1/biosversion_types.go, api/v1alpha1/bmcsettings_types.go, api/v1alpha1/bmcversion_types.go, api/v1alpha1/bmc_types.go, api/v1alpha1/server_types.go, api/v1alpha1/zz_generated.deepcopy.go
Defines DriftPolicy string enum with Observe/Suspend constants. Adds DriftPolicy, SettingsFlow []SettingsFlowItem, and multi-ref list fields (BMCSettingsRefs, BIOSSettingsRefs) to all relevant specs. Marks deprecated single-ref fields. Adds CEL/XValidation rules enforcing serverRef/bmcRef presence, non-empty version, and mutual exclusivity between settings and settingsFlow. Updates generated deepcopy for new slice fields.
Apply-configuration and embedded schema regeneration
api/v1alpha1/applyconfiguration/api/v1alpha1/biossettingsspec.go, api/v1alpha1/applyconfiguration/api/v1alpha1/biosversionspec.go, api/v1alpha1/applyconfiguration/api/v1alpha1/bmcsettingsspec.go, api/v1alpha1/applyconfiguration/api/v1alpha1/bmcsettingstemplate.go, api/v1alpha1/applyconfiguration/api/v1alpha1/bmcspec.go, api/v1alpha1/applyconfiguration/api/v1alpha1/bmcversionspec.go, api/v1alpha1/applyconfiguration/api/v1alpha1/serverspec.go, api/v1alpha1/applyconfiguration/internal/internal.go
Regenerates all apply-configuration structs and fluent builder methods (WithDriftPolicy, WithSettingsFlow, WithBMCSettingsRefs, WithBIOSSettingsRefs) for modified spec types. Updates the embedded structured-merge-diff schema YAML to register new field types including the DriftPolicy scalar and atomic list fields.
CRD YAML schema updates
config/crd/bases/metal.ironcore.dev_biossettings.yaml, config/crd/bases/metal.ironcore.dev_biossettingssets.yaml, config/crd/bases/metal.ironcore.dev_biosversions.yaml, config/crd/bases/metal.ironcore.dev_bmcs.yaml, config/crd/bases/metal.ironcore.dev_bmcsettings.yaml, config/crd/bases/metal.ironcore.dev_bmcsettingssets.yaml, config/crd/bases/metal.ironcore.dev_bmcversions.yaml, config/crd/bases/metal.ironcore.dev_servers.yaml, docs/api-reference/api.md
Adds driftPolicy enum fields, settingsFlow array schemas, and multi-ref list fields to all affected CRDs. Marks deprecated singular reference fields with notices and extends x-kubernetes-validations for required fields and mutual exclusivity between settings and settingsFlow. Updates API reference documentation.
Controller helper utilities
internal/controller/helper.go
Adds containsRef and removeRef helpers for operating on []LocalObjectReference by name. Adds flattenSettingsFlow to sort SettingsFlowItems by ascending priority and merge their Settings maps for effective configuration computation.
Controller reconcile migration
internal/controller/biossettings_controller.go, internal/controller/bmcsettings_controller.go, internal/controller/bmcsettingsset_controller.go, internal/controller/biossettingsset_controller.go, internal/controller/bmc_controller.go, internal/controller/server_controller.go
Updates all controllers to use BMCSettingsRefs/BIOSSettingsRefs list fields and SettingsFlow instead of SettingsMap. Adds migration paths that move legacy BMCSettingRef/BIOSSettingsRef into the list and clear the deprecated field on first reconcile. Replaces direct SettingsMap usage with flattenSettingsFlow. Switches set-controller duplicate-avoidance to cluster-wide (name, version) scan. Updates watch predicates and enqueueing to use plural ref fields.
Webhook validation: DriftPolicy and new duplicate-detection helpers
internal/webhook/v1alpha1/helper.go, internal/webhook/v1alpha1/biossettings_webhook.go, internal/webhook/v1alpha1/biosversion_webhook.go, internal/webhook/v1alpha1/bmcsettings_webhook.go, internal/webhook/v1alpha1/bmcversion_webhook.go
Adds validateDriftPolicy rejecting driftPolicy on objects without owner references. Adds four duplicate-detection helpers matching on (serverRef/bmcRef, version) pairs. Updates all four webhook validators to call these on create and update, removing old single-field duplicate checkers.
Controller and webhook test updates
internal/controller/biossettings_controller_test.go, internal/controller/bmcsettings_controller_test.go, internal/controller/bmcsettingsset_controller_test.go, internal/controller/biossettingsset_controller_test.go, internal/controller/bmc_controller_test.go, internal/controller/server_controller_test.go, internal/webhook/v1alpha1/biossettings_webhook_test.go, internal/webhook/v1alpha1/biosversion_webhook_test.go, internal/webhook/v1alpha1/bmcsettings_webhook_test.go, internal/webhook/v1alpha1/bmcversion_webhook_test.go
Updates all controller and webhook tests to assert Spec.BIOSSettingsRefs/BMCSettingsRefs (list) and SettingsFlow instead of deprecated singular fields and flat maps. Adds two new migration tests verifying SettingsMap→SettingsFlow and BMCSettingRef→BMCSettingsRefs migration on first reconcile.

122-150: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Enforce unique settingsFlow.priority to keep precedence deterministic.

settingsFlow is order-defining, but the schema doesn’t prevent duplicate priorities. With priority-based flatten/merge, equal priorities make effective override order ambiguous. Add a CEL uniqueness rule for priority (optionally name too).

Suggested schema rule
 x-kubernetes-validations:
 - message: version is required on BIOSSettings
   rule: size(self.version) > 0
 - message: serverRef is required
   rule: has(self.serverRef)
+ - message: settingsFlow priorities must be unique
+   rule: '!has(self.settingsFlow) || self.settingsFlow.all(i, self.settingsFlow.filter(j, j.priority == i.priority).size() == 1)'

bmcSettingsRefsList and deprecation guidance are inconsistent.

The deprecated field instructs users to migrate to bmcSettingsRefs, but the actual new schema property is bmcSettingsRefsList. This creates an API contract mismatch for clients/manifests. Pick one canonical field name and align API types, CRD schema, and migration guidance consistently.

As per coding guidelines, this CRD is generated; fix the source API field/markers and regenerate manifests.

Inline comments:
In `@api/v1alpha1/biosversion_types.go`:
- Around line 70-73: The ServerRef field in the BiosVersion type has a
conflicting +optional marker that contradicts its required nature enforced by
the XValidation rule and the absence of omitempty in the JSON tag. Remove the
+optional marker comment from the ServerRef field definition to align the API
schema markers with the actual field requirements.

In `@api/v1alpha1/bmc_types.go`:
- Around line 59-67: The deprecation comment for the BMCSettingRef field
instructs users to use "bmcSettingsRefs" as the replacement, but the actual JSON
serialization tag for the BMCSettingsRefs field is "bmcSettingsRefsList". Update
the deprecation comment for BMCSettingRef to reference the correct serialized
field name "bmcSettingsRefsList" instead of "bmcSettingsRefs" so that YAML
authors receive accurate migration guidance.

In `@config/crd/bases/metal.ironcore.dev_bmcsettings.yaml`:
- Around line 126-130: The deprecation description for the settings field states
that settingsFlow takes precedence when both fields are set, but the CEL
validation rules currently reject any configuration where both settings and
settingsFlow are provided simultaneously. To fix this, either update the
deprecation description to accurately reflect that both fields cannot be set
together (align documentation with actual validation), or modify the CEL
validation rules to allow both fields to be present and ensure that the
settingsFlow field actually takes precedence during processing when both are
specified. Apply the same fix to all similar occurrences of this pattern in the
file (referenced at lines 302-304).

In `@internal/controller/bmc_controller.go`:
- Around line 102-110: When r.Get returns NotFound for a BMCSettings object, the
code ignores the error but proceeds to call r.Delete on the unpopulated
bmcSettings struct, which will fail because the object metadata is not
populated. Wrap the r.Delete call with client.IgnoreNotFound to handle the case
where the BMCSettings object no longer exists. Apply this fix to both the main
loop block (the for loop iterating over bmcObj.Spec.BMCSettingsRefs) and the
legacy block that handles deletion of old BMCSettings objects, ensuring that
Delete failures due to missing objects are safely ignored.

In `@internal/controller/helper.go`:
- Around line 630-648: The flattenSettingsFlow function has inverted priority
merge semantics. The comment states that higher-priority items (lower numbers)
should win on conflicts, but the current code sorts in ascending order and
applies items sequentially with maps.Copy, causing later items to overwrite
earlier ones. This means lower-priority items (higher numbers) actually win,
contradicting the documented behavior. Fix this by modifying the SortFunc
comparison to sort in descending order instead, so that higher-priority items
with lower priority numbers are applied last and thus overwrite lower-priority
items, aligning the implementation with the documented intent.

In `@internal/webhook/v1alpha1/helper.go`:
- Around line 59-61: The field path casing in the Child method call is
inconsistent with the JSON tag definition. Locate the line in helper.go that
contains field.NewPath("spec").Child("BMCRef") and change the string "BMCRef" to
"bmcRef" (lowercase) to match the JSON tag casing. This will ensure consistency
with the correct field path casing used elsewhere in the file (such as on line
102) and ensure validation error messages display the correct field names as
defined in the CRD schema.

In `@docs/api-reference/api.md` around lines 1820 - 1821, Fix the typo in the
biosSettingsRefsList field description in the ServerSpec documentation. In the
description text where it currently reads "the BIOS configuration for t1his
server", change "t1his" to "this" so it reads "the BIOS configuration for this
server".

  1. Stale biosSettingsRef after deletion — cleanupReferences replaced the old BIOSSettingsRef.Name == settings.Name check with containsRef(BIOSSettingsRefs, ...). For any Server that hasn't been migrated yet, deletion of the BIOSSettings leaves the deprecated pointer set permanently. Data is silently inconsistent with no error surfaced.

  2. Same bug on BMC side — identical regression in cleanupReferences for BMCSettings. The old code explicitly checked bmcObj.Spec.BMCSettingRef.Name == settings.Name; the new code only checks containsRef(BMCSettingsRefs, ...). Same permanent stale-pointer outcome.

  3. Finalizer gap in SettingsMap migration — the migration patch returns before PatchEnsureFinalizer runs. If the object is deleted in that window, shouldDelete routes to delete() but no finalizer is present, so cleanup is skipped entirely and the BMC keeps a stale entry in bmcSettingsRefsList.

  4. bmcSettingsRefsList JSON tag — Go field BMCSettingsRefs serializes as bmcSettingsRefsList. Any field-selector query, index registration, or tool that derives the path from the Go struct name silently finds nothing. Worth fixing before the field becomes load-bearing in production tooling.
