Faster Container Image Distribution on a Variety of Tools with Lazy Pulling

Explore cutting-edge techniques for faster container image distribution in this conference talk from KubeCon + CloudNativeCon Europe 2022. Dive into the world of lazy pulling, a method that allows container runtimes to start containers without waiting for the entire image to download. Learn about state-of-the-art OCI-alternative image formats, focusing on eStargz and nydus, and their implementation across various container-related tools such as Kubernetes, containerd, CRI-O, Podman, and BuildKit. Discover the benchmarking results, conversion processes, and ongoing discussions surrounding OCI Image Specification extensions. Gain insights into the FUSE/virtiofs unified architecture, registry acceleration file systems, and the community's requirements for V2 Image Spec. By the end of this talk, understand how these innovative approaches can significantly reduce pull times and improve container lifecycle efficiency in your cloud-native environments.
