)

func (ErrorType) String 

func (et ErrorType) String() string

type ImagePullError 

type ImagePullError struct {
	Code      ErrorType
	RootCause error
}

func (ImagePullError) Error 

func (ipe ImagePullError) Error() string

func (*ImagePullError) String

type ImagePullStats 

type ImagePullStats struct {
	CreateDuration *time.Duration

	TotalDuration  *time.Duration
	TarFileSizeMBs *int
	Err            *ImagePullError
}

type ImagePuller

}

func NewImagePuller 

func NewImagePuller() *ImagePuller

func (*ImagePuller) PullImage 

func (ip *ImagePuller) PullImage(image common.Image) ImagePullStats

PullImage gives us access to a docker image by:

  1. hitting a docker create endpoint (?)
  2. pulling down the newly created image and saving as a tarball

It does this by accessing the host's docker daemon, locally, over the docker socket. This gives us a window into any images that are local.
