.SH NAME
.PP
containers\-storage apply\-diff \- Apply a layer diff to a layer

.SH SYNOPSIS
.PP
\fBcontainers\-storage\fP \fBapply\-diff\fP [\fIoptions\fP [...]] \fIlayerNameOrID\fP [\fIreferenceLayerNameOrID\fP]

.SH DESCRIPTION
.PP
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
\fIcontainers\-storage diff\fP or an equivalent.

.PP
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 \fBskopeo\fP\&.

.SH OPTIONS
.PP
\fB\-f | \-\-file\fP \fIfilename\fP

.PP
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.
