nerdctl is a Docker-compatible CLI of containerd, developed as a subproject of containerd. nerdctl recently added support of P2P image distribution on IPFS. This enables to share container images among hosts without hosting or relying on the registry.

In this session, Kohei, one of the maintainers of nerdctl, will introduce IPFS-based P2P image distribution with containerd and nerdctl. This session will also show the combination of IPFS-based distribution with the existing image distribution techniques, focusing on lazy pulling (eStargz) and image encryption (OCIcrypt). The status of integration work with other tools including Kubernetes will also be shared.
