Types

type ImageCache

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

ImageCache wraps caching.Cache such that we don't need to do any casting inside the engine and sandbox implementations

func New

func New(d *docker.Client, tracker gc.ResourceTracker, monitor runtime.Monitor) *ImageCache

New creates a new ImageCache object

func (*ImageCache) ImageSchema

func (ic *ImageCache) ImageSchema() schematypes.Schema

ImageSchema returns the JSON schema by which images can be specified when ImageCache.Require is called

func (*ImageCache) Require

func (ic *ImageCache) Require(ctx *runtime.TaskContext, imagePayload interface{}) (*ImageHandle, error)

Require that an image is loaded or returned from cache. The imagePayload given must satisfy ImageCache.ImageSchema()

type ImageHandle

type ImageHandle struct {
	*caching.Handle
	ImageName string
}

ImageHandle wraps caching.Handle such that we don't need to do any casting to access the ImageName
