Welcome to the image-service wiki!

Dragonfly image-service (Nydus) is a container image acceleration tool. It is written in rust. It was developed at Alibaba Cloud and Ant Group. The project designs and implements user space filesystem on top of a container image format that improves over the current OCI image specification.

Features

• Container images are downloaded on demand
• Chunk level data duplication
• Flatten image metadata and data to remove all intermediate layers
• Only usable image data is saved when building a container image
• Only usable image data is downloaded when running a container
• End-to-end image data integrity
• Compactible with the OCI artifacts spec and distribution spec
• Integrated with existing CNCF project dragonfly to support image distribution in large clusters
• Different container image storage backends are supported
