示例1: pushV2Layer
func (p *v2Pusher) pushV2Layer(bs distribution.BlobService, l layer.Layer) (digest.Digest, error) {
out := p.config.OutStream
displayID := stringid.TruncateID(string(l.DiffID()))
out.Write(p.sf.FormatProgress(displayID, "Preparing", nil))
arch, err := l.TarStream()
if err != nil {
return "", err
}
// Send the layer
layerUpload, err := bs.Create(context.Background())
if err != nil {
return "", err
}
defer layerUpload.Close()
// don't care if this fails; best effort
size, _ := l.DiffSize()
reader := progressreader.New(progressreader.Config{
In: ioutil.NopCloser(arch), // we'll take care of close here.
Out: out,
