## containers-storage-import-layer 1 "April 2019"
|
|
|
|
## NAME
|
|
containers-storage import-layer - Import files to a new layer
|
|
|
|
## SYNOPSIS
|
|
**containers-storage** **import-layer** [*options* [...]] [*parentLayerNameOrID*]
|
|
|
|
## DESCRIPTION
|
|
This subcommand is a combination of *containers-storage create-layer* and
|
|
*containers-storage apply-diff*.
|
|
|
|
When a layer is first created with *containers-storage create-layer*, 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
|
|
by running *containers-storage apply-diff*.
|
|
|
|
## OPTIONS
|
|
**-n** *name*
|
|
|
|
Sets an optional name for the layer. If a name is already in use, an error is
|
|
returned.
|
|
|
|
**-i | --id** *ID*
|
|
|
|
Sets the ID for the layer. If none is specified, one is generated.
|
|
|
|
**-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.
|
|
|
|
**-l | --label** *mount-label*
|
|
|
|
Sets the label which should be assigned as an SELinux context when mounting the
|
|
layer.
|
|
|
|
**-r | --readonly**
|
|
|
|
Mark the layer as readonly.
|
|
|
|
**-j | --json**
|
|
|
|
Prefer JSON output.
|
|
|
|

|
|
|
|
**--gidmap**
|
|
|

|
|
|
|
**--hostuidmap**
|
|
|
|

|
|
|
|

|
|
