Types

type CopyOptions

type CopyOptions struct {
	SigstorePrivateKey string
	SigstorePassphrase []byte
	RemoveSignatures   bool
	CopyProvenance     bool

	Destination *destination.Destination
	Set         types.FilterSet
	Policy      *signaturev5.Policy
}

type Option

type Option struct {
	// Image Type.
	Type types.ImageType
	// Directory, need to provide if Type is dir / oci / docker-archive
	Directory string
	// Registry, need to provide if Type is docker, docker-daemon, docker-archive
	Registry string
	// Project (also called namespace on some public cloud providers),
	// need to provide if Type is docker / docker-daemon / docker-archive
	Project string
	// Image name, need to provide if Type is docker / docker-daemon / docker-archive
	Name string
	// Image tag, need to provide if Type is docker / docker-daemon / docker-archive
	Tag string
	// Digest is used to identify the Digest of the image to be copied,
	// only available when Type is docker.
	Digest digest.Digest

	SystemContext *typesv5.SystemContext
}

Option is used for create the Source object.

type ScanOptions

type ScanOptions struct {
	Set types.FilterSet
}

type SignOptions

type SignOptions struct {
	SigstorePrivateKey string
	SigstorePassphrase []byte
	Set                types.FilterSet
	Policy             *signaturev5.Policy
}

type Source

type Source struct {
	// contains filtered or unexported fields
}

Source represents the source image to be copied or sign. The type of the source image can be: docker, docker-daemon, docker-archive, oci or dir

func NewSource

func NewSource(o *Option) (*Source, error)

NewSource is the constructor to create a Source object. Need to call Init method after creating the Source object before use.

func (*Source) Copy

	ctx context.Context,
	opts *CopyOptions,
) error

func (*Source) Directory

func (s *Source) Directory() string

func (*Source) GetCopiedImage

func (s *Source) GetCopiedImage() *archive.Image

func (*Source) ImageBySet

func (s *Source) ImageBySet(
	set types.FilterSet, copyProvenance bool,
) *archive.Image

func (*Source) Init

func (s *Source) Init(ctx context.Context) error

Init initialize the source image manifest.

func (*Source) InspectRAW

func (s *Source) InspectRAW(ctx context.Context) ([]byte, string, error)

func (*Source) IsSigstoreSignature

func (s *Source) IsSigstoreSignature() bool

IsSigstoreSignature detects whether the source image is a sigstore signature
