Functions

func New

func New(config *Config,
	generator kubecontainer.RunContainerOptionsGenerator,
	recorder record.EventRecorder,
	containerRefManager *kubecontainer.RefManager,
	readinessManager *kubecontainer.ReadinessManager,
	volumeGetter volumeGetter) (kubecontainer.Runtime, error)

New creates the rkt container runtime which implements the container runtime interface. It will test if the rkt binary is in the $PATH, and whether we can get the version of it. If so, creates the rkt container runtime, otherwise returns an error.

Types

type Config

type Config struct {
	// The debug flag for rkt.
	Debug bool
	// The rkt data directory.
	Dir string
	// This flag controls whether we skip image or key verification.
	InsecureSkipVerify bool
	// The local config directory.
	LocalConfigDir string
}

Config stores the global configuration for the rkt runtime. Run 'rkt' for more details.

type ImageManager

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

ImageManager manages and garbage collects the container images for rkt.

func NewImageManager

func NewImageManager(r *runtime) *ImageManager

func (*ImageManager) GarbageCollect

func (im *ImageManager) GarbageCollect() error

GarbageCollect collects the images. It is not implemented by rkt yet.
