Functions

func NewContainerdSnapshotter

func NewContainerdSnapshotter(s Snapshotter) (snapshots.Snapshotter, func() error)

NewContainerdSnapshotter converts snapshotter to containerd snapshotter

Types

type Blobmapper

type Blobmapper interface {
	GetBlob(ctx context.Context, key string) (digest.Digest, digest.Digest, error)
	SetBlob(ctx context.Context, key string, diffID, blob digest.Digest) error
}

type Mountable

type Mountable interface {
	// ID() string
	Mount() ([]mount.Mount, error)
	Release() error
	IdentityMapping() *idtools.IdentityMapping
}

type Mounter

type Mounter interface {
	Mount() (string, error)
	Unmount() error
}

func LocalMounter

func LocalMounter(mountable Mountable) Mounter

LocalMounter is a helper for mounting mountfactory to temporary path. In addition it can mount binds without privileges

func LocalMounterWithMounts

func LocalMounterWithMounts(mounts []mount.Mount) Mounter

LocalMounterWithMounts is a helper for mounting to temporary path. In addition it can mount binds without privileges

type Snapshotter

type Snapshotter interface {
