Nydus-localdisk

Nydus localdisk is a new backend implementation of Nydus. This repo mainly contains tools and libraries related to localdisk image generation

Overview

The localdisk backend can store nydus images to local raw disk. In this backend, each Nydus mirror corresponds to a block device, each layer of the mirror is mapped to a partition of the block device, and the partition is located through the GPT partition table.

Building

cd cmd/nydus-localdisk go build

Usage

Nydus localdisk generator converts a Nydus image from the source registry to a gpt disk image file in localdisk format.

nydus-localdisk $IMAGE_PATH $TARGET_DIR

If you only have an OCI image, you can use Nydusify to convert it to a Nydus image first, and then use this tool to generate a Nydus localdisk image file.

Import Library
