Types ¶
type Fetcher ¶
type Fetcher interface { // Fetch the resource identified by the descriptor. Fetch(ctx context.Context, desc ocispec.Descriptor) (io.ReadCloser, error) }
Fetcher fetches content.
type PushRequest ¶
type PushRequest interface { // Commit commits the blob (but no roll-back is guaranteed on an error). // size and expected can be zero-value when unknown. // Commit always closes the writer, even on error. // ErrAlreadyExists aborts the writer. Commit(ctx context.Context, size int64, expected digest.Digest, opts ...content.Opt) error // Status returns the current state of write Status() (content.Status, error) }
PushRequest handles the result of a push request replaces containerd content.Writer.
type Pusher ¶
type Pusher interface { // Push returns a push request for the given resource identified // by the descriptor and the given data source. Push(ctx context.Context, d ocispec.Descriptor, src Source) (PushRequest, error) }
Pusher pushes content don't use write interface of containerd remotes.Pusher.
type Resolver ¶
type Resolver interface { // Resolve attempts to resolve the reference into a name and descriptor. // // The argument `ref` should be a scheme-less URI representing the remote. // Structurally, it has a host and path. The "host" can be used to directly // reference a specific host or be matched against a specific handler. // // The returned name should be used to identify the referenced entity. // Dependending on the remote namespace, this may be immutable or mutable. // While the name may differ from ref, it should itself be a valid ref. // // If the resolution fails, an error will be returned. Resolve(ctx context.Context, ref string) (name string, desc ocispec.Descriptor, err error) // Fetcher returns a new fetcher for the provided reference. // All content fetched from the returned fetcher will be // from the namespace referred to by ref. Fetcher(ctx context.Context, ref string) (Fetcher, error) // Pusher returns a new pusher for the provided reference // The returned Pusher should satisfy content.Ingester and concurrent attempts // to push the same blob using the Ingester API should result in ErrUnavailable. Pusher(ctx context.Context, ref string) (Pusher, error) Lister(ctx context.Context, ref string) (Lister, error) }
Resolver provides remotes based on a locator.
type Source ¶
type Source interface {
Reader() (io.ReadCloser, error)
}
