📝 Walkthrough

Walkthrough

Removed the KMSEncryptionProvider feature gate and its test YAML and feature-gate registration entries. Replaced AWS-specific KMS configuration with a Vault-based provider: added spec.encryption.kms.type: "Vault" and spec.encryption.kms.vault (fields include vaultAddress, kmsPluginImage, approleSecretRef, transitKey, optional tls and transitMount/vaultNamespace). Updated Go API annotations and CRD validations to reference the KMSEncryption feature gate and adjusted payload feature-gate manifests to remove KMSEncryptionProvider entries.

67-73: ⚠️ Potential issue | 🟠 Major

Add the length validators promised by the API contract.

The documentation states bounds for vaultNamespace (1-256), transitMount (1-128), and transitKey (1-128), but the kubebuilder markers are missing. This allows empty strings and arbitrarily long values to pass schema validation, causing runtime failures instead of admission-time rejection.

Suggested fix for vaultNamespace (lines 67-73)
 	// vaultNamespace specifies the Vault namespace where the Transit secrets engine is mounted.
 	// This is only applicable for Vault Enterprise installations.
 	// The value can be between 1 and 256 characters.
 	// When this field is not set, no namespace is used.
 	//
+	// +kubebuilder:validation:MinLength=1
+	// +kubebuilder:validation:MaxLength=256
 	// +optional
 	VaultNamespace string `json:"vaultNamespace,omitempty"`
Suggested fix for transitMount (lines 128-134)
 	// transitMount specifies the mount path of the Vault Transit engine.
 	// The value can be between 1 and 128 characters.
 	// When this field is not set, it defaults to "transit".
 	//
+	// +kubebuilder:validation:MinLength=1
+	// +kubebuilder:validation:MaxLength=128
 	// +kubebuilder:default="transit"
 	// +optional
 	TransitMount string `json:"transitMount,omitempty"`
Suggested fix for transitKey (lines 136-141)
 	// transitKey specifies the name of the encryption key in Vault's Transit engine.
 	// This key is used to encrypt and decrypt data.
 	// The value must be between 1 and 128 characters.
 	//
+	// +kubebuilder:validation:MinLength=1

Require HTTPS for the Vault endpoint.

Allowing http:// enables cleartext transmission of AppRole credentials and KMS traffic. The tlsVerify: SkipVerify option already covers insecure testing scenarios without disabling transport encryption entirely.

342-346: Validation message references KMSEncryption feature gate but rule doesn't enforce it.

The message says "kms config is required when encryption type is KMS and KMSEncryption feature gate is enabled" but the CEL rule itself doesn't check the feature gate state—it just validates kms presence based on type == 'KMS'. This is likely correct behavior (the feature gate controls schema presence, not this runtime rule), but the message is potentially misleading.

Consider simplifying the message to match the actual rule behavior:

-- message: kms config is required when encryption type is KMS and
-    KMSEncryption feature gate is enabled, and forbidden otherwise

Preserve an upgrade path for existing aws KMS configs.

This change removes aws from the public kms union and provider enum without a deprecated member or any migration path in the API surface. Clusters that already persisted spec.encryption.kms.aws under the previous gate will be rejected on upgrade once this validation becomes authoritative.

AWS provider (e.g. add an Aws *AWSKMSConfig `json:"aws,omitempty"` with
appropriate +optional and +deprecated markers or a FeatureGate-aware validation
exception) and keep the union discriminator Type KMSProviderType accepting the
old "aws" enum value (or add a deprecated enum entry) so existing persisted
KMSConfig objects with Type == "AWS" and the Aws member continue to validate
during upgrade while new API users are prevented from creating new AWS configs.

In `@config/v1/types_kmsencryption.go`:
- Around line 37-79: The CRD manifests are out of sync with the VaultKMSConfig
Go type: the Go struct now uses kmsPluginImage and a nested TLS struct
(VaultTLSConfig with caBundle and serverName) but the published CRDs still
expose vaultKMSPluginImage, flat tlsCA/tlsServerName/tlsVerify and old
http:///length validations; update the CRD schema to match the Go API by
renaming fields (vaultKMSPluginImage -> kmsPluginImage), nesting TLS under tls
with caBundle and serverName fields, removing the old http:// rule and
correcting MinLength/MaxLength rules to match KMSPluginImage and VaultAddress,
then regenerate the CRD manifests (e.g., run your controller-gen/CRD generation
or project make target) so the published YAML matches VaultKMSConfig,
KMSPluginImage, VaultAddress and TLS/VaultTLSConfig definitions.

- Around line 5-24: The KMS union removed the previously allowed "aws" provider
with no migration or deprecated field, which will reject clusters that already
have spec.encryption.kms.aws; restore backward compatibility by reintroducing a
deprecated/hidden union member for the AWS provider (e.g. add an Aws
*AWSKMSConfig `json:"aws,omitempty"` with appropriate +optional and +deprecated
markers or a FeatureGate-aware validation exception) and keep the union
discriminator Type KMSProviderType accepting the old "aws" enum value (or add a
deprecated enum entry) so existing persisted KMSConfig objects with Type ==
"AWS" and the Aws member continue to validate during upgrade while new API users
are prevented from creating new AWS configs.

In `@config/v1/types_kmsencryption.go`:
- Around line 56-60: The XValidation on vaultAddress (self.matches('^https://'))
only enforces the prefix and allows invalid values like "https://"; update the
validation to either enforce a full URL shape (replace the XValidation rule with
a stronger regex/pattern that requires a host and optional port/path, e.g.
require at least "https://<host>" semantics) or, if you prefer the lighter
check, change the documentation/message to state "must start with 'https://'" to
match the current rule; update the kubebuilder:XValidation rule and the
vaultAddress comment/message accordingly so they are consistent (referencing the
vaultAddress field and its XValidation rule).
- Line 50: The XValidation message still references the old field name
vaultKMSPluginImage; update the validation annotation on the kmsPluginImage
field so the message uses the new field name (kmsPluginImage) and keep the rest
of the guidance unchanged. Locate the kubebuilder XValidation tag shown and
replace "vaultKMSPluginImage" in the message with "kmsPluginImage" so admission
errors point to the correct field.
