Functions

func GenericImageFromSource

func GenericImageFromSource(src types.ImageSource) types.Image

GenericImageFromSource returns a types.Image implementation for source. NOTE: This is currently an internal testing helper, do not rely on this as a stable API. There might be an ImageFromSource eventually, but it would not be in the skopeo/docker package.

func NewDockerImage

func NewDockerImage(img, certPath string, tlsVerify bool) (types.Image, error)

NewDockerImage returns a new Image interface type after setting up a client to the registry hosting the given image.

func NewDockerImageDestination

func NewDockerImageDestination(img, certPath string, tlsVerify bool) (types.ImageDestination, error)

NewDockerImageDestination creates a new ImageDestination for the specified image and connection specification.

func NewDockerImageSource

func NewDockerImageSource(img, certPath string, tlsVerify bool) (types.ImageSource, error)

NewDockerImageSource creates a new ImageSource for the specified image and connection specification.

Types

type Image

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

Image is a Docker-specific implementation of types.Image with a few extra methods which are specific to Docker.

func (*Image) DockerTar

func (i *Image) DockerTar() ([]byte, error)

TODO(runcom)

func (*Image) GetRepositoryTags

func (i *Image) GetRepositoryTags() ([]string, error)

GetRepositoryTags list all tags available in the repository. Note that this has no connection with the tag(s) used for this specific image, if any.

func (*Image) Inspect

func (i *Image) Inspect() (*types.ImageInspectInfo, error)

func (*Image) IntendedDockerReference

func (i *Image) IntendedDockerReference() string

IntendedDockerReference returns the full, unambiguous, Docker reference for this image, _as specified by the user_ (not as the image itself, or its underlying storage, claims). This can be used e.g. to determine which public keys are trusted for this image. May be "" if unknown.

func (*Image) Layers

func (i *Image) Layers(layers ...string) error

func (*Image) Manifest

func (i *Image) Manifest() ([]byte, error)

Manifest is like ImageSource.GetManifest, but the result is cached; it is OK to call this however often you need.

func (*Image) Signatures

func (i *Image) Signatures() ([][]byte, error)

Signatures is like ImageSource.GetSignatures, but the result is cached; it is OK to call this however often you need.

func (*Image) SourceRefFullName

func (i *Image) SourceRefFullName() (string, error)

SourceRefFullName returns a fully expanded name for the repository this image is in.
