Functions ¶

func Apply ¶

func Apply(ctx context.Context, root string, r io.Reader, opts ...ApplyOpt) (int64, error)

Apply applies a tar stream of an OCI style diff tar. See https://github.com/opencontainers/image-spec/blob/master/layer.md#applying-changesets

Diff returns a tar stream of the computed filesystem difference between the provided directories.

Produces a tar using OCI style file markers for deletions. Deleted files will be prepended with the prefix ".wh.". This style is based off AUFS whiteouts. See https://github.com/opencontainers/image-spec/blob/master/layer.md

func WriteDiff ¶

func WriteDiff(ctx context.Context, w io.Writer, a, b string) error

WriteDiff writes a tar stream of the computed difference between the provided directories.

Produces a tar using OCI style file markers for deletions. Deleted files will be prepended with the prefix ".wh.". This style is based off AUFS whiteouts. See https://github.com/opencontainers/image-spec/blob/master/layer.md
