## containers-storage-apply-diff 1 "August 2016"
|
|
|
|
## NAME
|
|
containers-storage apply-diff - Apply a layer diff to a layer
|
|
|
|
## SYNOPSIS
|
|
**containers-storage** **apply-diff** [*options* [...]] *layerNameOrID* [*referenceLayerNameOrID*]
|
|
|
|
## DESCRIPTION
|
|
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.
|
|
|
|
## EXAMPLE
|
|
**containers-storage apply-diff -f 71841c97e320d6cde.tar.gz layer1**
