Common errors

var ErrStopProcessing = fmt.Errorf("stop processing")

ErrStopProcessing is used to stop processing an oras operation. This error only makes sense in sequential pulling operation.

Functions

func Pull

func Pull(ctx context.Context, resolver remotes.Resolver, ref string, ingester content.Ingester, opts ...PullOpt) (ocispec.Descriptor, []ocispec.Descriptor, error)

Pull pull files from the remote

func Push

func Push(ctx context.Context, resolver remotes.Resolver, ref string, provider content.Provider, descriptors []ocispec.Descriptor, opts ...PushOpt) (ocispec.Descriptor, error)

Push pushes files to the remote

func ValidateNameAsPath

func ValidateNameAsPath(desc ocispec.Descriptor) error

ValidateNameAsPath validates name in the descriptor as file path in order to generate good packages intended to be pulled using the FileStore or the oras cli. For cross-platform considerations, only unix paths are accepted.

func WithPullByBFS

func WithPullByBFS(o *pullOpts) error

WithPullByBFS opt to pull in sequence with breath-first search

Types

type PullOpt

type PullOpt func(o *pullOpts) error

PullOpt allows callers to set options on the oras pull

func WithAdditionalCachedMediaTypes

func WithAdditionalCachedMediaTypes(cachedMediaTypes ...string) PullOpt

WithAdditionalCachedMediaTypes adds media types normally cached in memory when pulling. This does not replace the default media types, but appends to them

func WithAllowedMediaType

func WithAllowedMediaType(allowedMediaTypes ...string) PullOpt

WithAllowedMediaType sets the allowed media types

func WithAllowedMediaTypes

func WithAllowedMediaTypes(allowedMediaTypes []string) PullOpt

WithAllowedMediaTypes sets the allowed media types

func WithCachedMediaTypes

func WithCachedMediaTypes(cachedMediaTypes ...string) PullOpt

WithCachedMediaTypes sets the media types normally cached in memory when pulling.

func WithContentProvideIngester

func WithContentProvideIngester(store orascontent.ProvideIngester) PullOpt

WithContentProvideIngester opt to the provided Provider and Ingester for file system I/O, including caches.

func WithPullBaseHandler

func WithPullBaseHandler(handlers ...images.Handler) PullOpt

WithPullBaseHandler provides base handlers, which will be called before any pull specific handlers.

func WithPullCallbackHandler

func WithPullCallbackHandler(handlers ...images.Handler) PullOpt

WithPullCallbackHandler provides callback handlers, which will be called after any pull specific handlers.

func WithPullEmptyNameAllowed

func WithPullEmptyNameAllowed() PullOpt

WithPullEmptyNameAllowed allows pulling blobs with empty name.

func WithPullStatusTrack

func WithPullStatusTrack(writer io.Writer) PullOpt

WithPullStatusTrack report results to stdout

type PushOpt

type PushOpt func(o *pushOpts) error

PushOpt allows callers to set options on the oras push

func WithManifestAnnotations(annotations map[string]string) PushOpt

WithManifestAnnotations overrides the manifest annotations

func WithNameValidation

func WithNameValidation(validate func(desc ocispec.Descriptor) error) PushOpt

WithNameValidation validates the image title in the descriptor. Pass nil to disable name validation.

func WithPushBaseHandler

func WithPushBaseHandler(handlers ...images.Handler) PushOpt

WithPushBaseHandler provides base handlers, which will be called before any push specific handlers.

func WithPushStatusTrack

func WithPushStatusTrack(writer io.Writer) PushOpt

WithPushStatusTrack report results to a provided writer
