Types

type ImageManager interface {
	// EnsureImageExists ensures that image specified in `container` exists.
	EnsureImageExists(pod *api.Pod, container *api.Container, pullSecrets []api.Secret) (error, string)
}

ImageManager provides an interface to manage the lifecycle of images. Implementations of this interface are expected to deal with pulling (downloading), managing, and deleting container images. Implementations are expected to abstract the underlying runtimes. Implementations are expected to be thread safe.
