Overview
When a layer is first created, it contains no changes relative to its parent layer. The layer can either be mounted read-write and its contents modified directly, or contents can be added (or removed) by applying a layer diff. A layer diff takes the form of a (possibly compressed) tar archive with additional information present in its headers, and can be produced by running containers-storage diff or an equivalent.
Layer diffs are not typically applied manually. More often they are applied by a tool which is being used to import an entire image, such as skopeo.
Options
-f | --file filename
Specifies the name of a file from which the diff should be read. If this option is not used, the diff is read from standard input.
Examples
containers-storage apply-diff -f 71841c97e320d6cde.tar.gz layer1
