containers-storage-import-layer1

Usage

Overview

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

--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.
