## 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.
**--uidmap**
UID map specified in the format expected by *subuid*. It cannot be specified simultaneously with *--hostuidmap*.
**--gidmap**
GID map specified in the format expected by *subgid*. It cannot be specified simultaneously with *--hostuidmap*.
**--hostuidmap**
Force host UID map. It cannot be specified simultaneously with neither *--uidmap* nor *--subuidmap*.
**--hostgidmap**
Force host GID map. It cannot be specified simultaneously with neither *--gidmap* nor *--subgidmap*.
**--subuidmap** *username*
Create UID map for username using the data from /etc/subuid. It cannot be specified simultaneously with *--hostuidmap*.
**--subgidmap** *group-name*
Create GID map for group-name using the data from /etc/subgid. It cannot be specified simultaneously with *--hostuidmap*.
