oci-image-tool-create1

Usage

OCI Community JULY 2016

Overview

oci-image-tool create validates an application/vnd.oci.image.manifest.v1+json and unpacks its layered filesystem to dest/rootfs, although the target directory is configurable with --rootfs. See oci-image-tool unpack(1) for more details on this process.

Also translates the referenced config from application/vnd.oci.image.config.v1+json to a runtime-spec-compatible dest/config.json.

Options

--rootfs=""
A directory representing the root filesystem of the container in the OCI runtime bundle. It is strongly recommended to keep the default value. (default "rootfs")
