Functions

func NewSnapshotter

func NewSnapshotter(opt Opt) snapshot.Snapshotter

Types

type DiffPair

type DiffPair struct {
	Blobsum digest.Digest
	DiffID  digest.Digest
}

type Info

type Info struct {
	snapshots.Info
	Blob string
}

type Opt

type Opt struct {
	Content       content.Store
	Snapshotter   snapshot.SnapshotterBase
	MetadataStore *metadata.Store
}

type Snapshotter

type Snapshotter struct {
	snapshot.SnapshotterBase
	// contains filtered or unexported fields
}

func (*Snapshotter) GetBlob

func (s *Snapshotter) GetBlob(ctx context.Context, key string) (digest.Digest, digest.Digest, error)

func (*Snapshotter) Remove

func (s *Snapshotter) Remove(ctx context.Context, key string) error

Remove also removes a reference to a blob. If it is a last reference then it deletes it the blob as well Remove is not safe to be called concurrently

func (*Snapshotter) SetBlob

func (s *Snapshotter) SetBlob(ctx context.Context, key string, diffID, blobsum digest.Digest) error

Validates that there is no blob associated with the snapshot. Checks that there is a blob in the content store. If same blob has already been set then this is a noop.

func (*Snapshotter) Usage

func (s *Snapshotter) Usage(ctx context.Context, key string) (snapshots.Usage, error)
