What is it?
Dragonfly is a CNCF-graduated project that distributes large files, container images, OCI artifacts, AI/ML models, caches, logs and dependencies using peer-to-peer transfer. Instead of every node pulling the same data from a central origin, nodes share pieces with each other, which reduces load on registries and object storage at large scale.
The project is aimed at cloud-native architectures and is built around standards-based interfaces. It also offers an optional content-addressable filesystem that is used to speed up the launch of OCI containers.
The repository is written in Go and is licensed under Apache-2.0. Documentation is hosted at d7y.io, and the project has undergone a third-party security audit by Trail of Bits.
