Types ¶
type ImagePuller ¶
type ImagePuller interface {
ImagePull(ctx context.Context, image string, pushOptions dockerTypes.ImagePullOptions) (io.ReadCloser, error)
}
type ImagePusher ¶
type ImagePusher interface {
ImagePush(ctx context.Context, image string, pushOptions dockerTypes.ImagePushOptions) (io.ReadCloser, error)
}
type PullOrPush ¶
type PullOrPush struct {
// contains filtered or unexported fields
}
func NewPull ¶
func NewPull(r io.Reader) *PullOrPush
func NewPush ¶

func (*PullOrPush) Progress ¶
func (d *PullOrPush) Progress() float64
func (*PullOrPush) Wait ¶
func (d *PullOrPush) Wait(onUpdate func(*PullOrPush)) (string, error)
Wait processes a JSON stream (the body of an image pull docker HTTP response) and returns an error as soon as an error is encountered in the stream, or the digest could not be parsd aftere processing the entire stream. Otherwise, it returns the digest string and a no error. onUpdate is called whenever d.Progress() may return a different value from the previous call.
