     3  ## NAME
     4  containers-storage apply-diff - Apply a layer diff to a layer
     5  
     6  ## SYNOPSIS
     7  **containers-storage** **apply-diff** [*options* [...]] *layerNameOrID* [*referenceLayerNameOrID*]
     8  
     9  ## DESCRIPTION
    10  When a layer is first created, it contains no changes relative to its parent
    11  layer.  The layer can either be mounted read-write and its contents modified
    12  directly, or contents can be added (or removed) by applying a layer diff.  A
    13  layer diff takes the form of a (possibly compressed) tar archive with
    14  additional information present in its headers, and can be produced by running
    15  *containers-storage diff* or an equivalent.
    16  
    17  Layer diffs are not typically applied manually.  More often they are applied by
    18  a tool which is being used to import an entire image, such as **skopeo**.
    19  
    20  ## OPTIONS
    21  **-f | --file** *filename*
    22  
    23  Specifies the name of a file from which the diff should be read.  If this
    24  option is not used, the diff is read from standard input.
