package loader

import "k8s.io/apiserver/pkg/admission/plugin/policy/manifest/loader"

Package loader provides generic functionality to load policy and binding configurations from manifest files. It handles file reading, YAML/JSON decoding, manifest name validation (suffix + uniqueness), policy-specific manifest constraints, and binding-reference checking. Type-specific defaulting and validation (e.g., scheme-based defaulting via internal types) are injected by callers through the AcceptObjectFunc callbacks.

Index ¶

• Variables
• func LoadPolicyManifests[P, B metav1.Object]( dir string, decoder runtime.Decoder, acceptPolicy AcceptObjectFunc[P], acceptBinding AcceptObjectFunc[B], getBindingPolicyName func(B) string, ) ([]P, []B, string, error)
• type AcceptObjectFunc

Variables ¶

var ErrUnrecognizedType = fmt.Errorf("unrecognized resource type")

ErrUnrecognizedType is returned by AcceptObjectFunc when the object type is not handled. This allows callers with multiple accept functions to try the next one.

Functions ¶

func LoadPolicyManifests ¶

func LoadPolicyManifests[P, B metav1.Object](
	dir string,
	decoder runtime.Decoder,
	acceptPolicy AcceptObjectFunc[P],
	acceptBinding AcceptObjectFunc[B],
	getBindingPolicyName func(B) string,
) ([]P, []B, string, error)

LoadPolicyManifests is a generic helper that loads policy and binding manifests from a directory. It handles file I/O, decoding, v1.List unwrapping, manifest name validation, policy-specific manifest constraints, binding-reference checking, and deterministic sorting by name. The decoder should be created by the caller with whatever scheme is appropriate (e.g., with full internal type install for kube-apiserver, or a minimal v1-only scheme for other consumers).

Types ¶

type AcceptObjectFunc ¶

type AcceptObjectFunc[T metav1.Object] func(obj runtime.Object) ([]T, error)

AcceptObjectFunc extracts typed items from a decoded runtime.Object, applying defaulting and validation. Returns ErrUnrecognizedType if the object type is not handled by this function.
