Types

type BlobCache

type BlobCache struct {
	// contains filtered or unexported fields
}

BlobCache is an object which saves copies of blobs that are written to it while passing them through to some real destination, and which can be queried directly in order to read them back.

Implements types.ImageReference.

func NewBlobCache

func NewBlobCache(ref types.ImageReference, directory string, compress types.LayerCompression) (*BlobCache, error)

NewBlobCache creates a new blob cache that wraps an image reference. Any blobs which are written to the destination image created from the resulting reference will also be stored as-is to the specified directory or a temporary directory. The compress argument controls whether or not the cache will try to substitute a compressed or different version of a blob when preparing the list of layers when reading an image.
