var ErrSkipChildren = errors.New("skip child entities")

ErrSkipChildren is a special error that may be returned from a Mutator to skip processing of an index's child entities.

Functions

func AppendManifests 

func AppendManifests(base v1.ImageIndex, adds ...IndexAddendum) oci.SignedImageIndex

AppendManifests is a form of mutate.AppendManifests that produces an oci.SignedImageIndex. The index itself will contain no signatures, but allows access to the contained signed entities.

func AppendSignatures 

func AppendSignatures(base oci.Signatures, sigs ...oci.Signature) (oci.Signatures, error)

AppendSignatures produces a new oci.Signatures with the provided signatures appended to the provided base signatures.

func AttachAttestationToEntity 

func AttachAttestationToEntity(se oci.SignedEntity, att oci.Signature, opts ...SignOption) (oci.SignedEntity, error)

AttachAttestationToEntity attaches the provided attestation to the provided entity.

func AttachAttestationToImage 

func AttachAttestationToImage(si oci.SignedImage, att oci.Signature, opts ...SignOption) (oci.SignedImage, error)

AttachAttestationToImage attaches the provided attestation to the provided image.

func AttachAttestationToImageIndex 

func AttachAttestationToImageIndex(sii oci.SignedImageIndex, att oci.Signature, opts ...SignOption) (oci.SignedImageIndex, error)

AttachAttestationToImageIndex attaches the provided attestation to the provided image index.

func AttachFileToEntity added in v1.4.0 

func AttachFileToEntity(se oci.SignedEntity, name string, f oci.File, opts ...SignOption) (oci.SignedEntity, error)

AttachFileToEntity attaches the provided file to the provided entity.

func AttachFileToImage added in v1.4.0 

func AttachFileToImage(si oci.SignedImage, name string, f oci.File, opts ...SignOption) (oci.SignedImage, error)

AttachFileToImage attaches the provided file to the provided image.

func AttachFileToImageIndex added in v1.4.0 

func AttachFileToImageIndex(sii oci.SignedImageIndex, name string, f oci.File, opts ...SignOption) (oci.SignedImageIndex, error)

AttachFileToImageIndex attaches the provided file to the provided image index.

func AttachSignatureToEntity 

func AttachSignatureToEntity(se oci.SignedEntity, sig oci.Signature, opts ...SignOption) (oci.SignedEntity, error)

AttachSignatureToEntity attaches the provided signature to the provided entity.

func AttachSignatureToImage 

func AttachSignatureToImage(si oci.SignedImage, sig oci.Signature, opts ...SignOption) (oci.SignedImage, error)

AttachSignatureToImage attaches the provided signature to the provided image.

func AttachSignatureToImageIndex 

func AttachSignatureToImageIndex(sii oci.SignedImageIndex, sig oci.Signature, opts ...SignOption) (oci.SignedImageIndex, error)

AttachSignatureToImageIndex attaches the provided signature to the provided image index.

func IsAfterChildren 

func IsAfterChildren(ctx context.Context) bool

IsAfterChildren is true within a Mutator when it is called after the children have been processed; however, this call is only made if the set of children changes since the Before call.

func IsBeforeChildren 

func IsBeforeChildren(ctx context.Context) bool

IsBeforeChildren is true within a Mutator when it is called before the children have been processed.

func Map 

func Map(ctx context.Context, parent oci.SignedEntity, fn Fn) (oci.SignedEntity, error)

Map calls `fn` on the signed entity and each of its constituent entities (`SignedImageIndex` or `SignedImage`) transitively. Any errors returned by an `fn` are returned by `Map`.

func ReplaceSignatures added in v1.4.0 

func ReplaceSignatures(base oci.Signatures) (oci.Signatures, error)

ReplaceSignatures produces a new oci.Signatures provided by the base signatures replaced with the new oci.Signatures.

func Signature added in v1.5.0 

func Signature(original oci.Signature, opts ...SignatureOption) (oci.Signature, error)

Signature returns a new oci.Signature based on the provided original, plus the requested mutations.

Types

type Appendable 

type Appendable interface {
	oci.SignedEntity
	mutate.Appendable
}

Appendable is our signed version of mutate.Appendable

type DupeDetector 

type DupeDetector interface {
	Find(oci.Signatures, oci.Signature) (oci.Signature, error)
}

DupeDetector scans a list of signatures looking for a duplicate.

type Fn 

type Fn func(context.Context, oci.SignedEntity) (oci.SignedEntity, error)

Fn is the signature of the callback supplied to Map. The oci.SignedEntity is either an oci.SignedImageIndex or an oci.SignedImage. This callback is called on oci.SignedImageIndex *before* its children are processed with a context that returns IsBeforeChildren(ctx) == true. If the images within the SignedImageIndex change after the Before pass, then the Fn will be invoked again on the new SignedImageIndex with a context that returns IsAfterChildren(ctx) == true. If the returned entity is nil, it is filtered from the result of Map.

type IndexAddendum 

type IndexAddendum struct {
	Add Appendable
	v1.Descriptor
}

IndexAddendum is our signed version of mutate.IndexAddendum

type ReplaceOp added in v1.4.0 

type ReplaceOp interface {
	Replace(oci.Signatures, oci.Signature) (oci.Signatures, error)
}

type SignOption 

type SignOption func(*signOpts)

func WithDupeDetector 

func WithDupeDetector(dd DupeDetector) SignOption

WithDupeDetector configures Sign* to use the following DupeDetector to avoid attaching duplicate signatures.

func WithReplaceOp added in v1.4.0 

func WithReplaceOp(ro ReplaceOp) SignOption

type SignatureOption added in v1.5.0 

type SignatureOption func(*signatureOpts)

func WithAnnotations added in v1.5.0 

func WithAnnotations(annotations map[string]string) SignatureOption

WithAnnotations specifies the annotations the Signature should have.

func WithBundle added in v1.5.0 

func WithBundle(b *bundle.RekorBundle) SignatureOption

WithBundle specifies the new Bundle the Signature should have.

func WithCertChain added in v1.5.0 

func WithCertChain(cert, chain []byte) SignatureOption

WithCertChain specifies the new cert and chain the Signature should have.

func WithMediaType added in v1.5.0 

func WithMediaType(mediaType types.MediaType) SignatureOption

WithMediaType specifies the new MediaType the Signature should have.
