BuildKit - A Modern Builder Toolkit on Top of containerd

Overview

Explore the capabilities of BuildKit, a modern OCI image builder toolkit based on containerd, in this 35-minute conference talk. Learn how BuildKit can significantly improve application development processes and CI workflows by enhancing Dockerfile performance and enabling remote caching support. Discover how BuildKit leverages containerd manifest list support to build multi-platform images with a single build request and Dockerfile. Gain insights into using BuildKit as part of the Docker platform or as a standalone tool deployed on a Kubernetes cluster, and understand its advantages over previous image building methods. Delve into topics such as BuildKit LLB, extensible syntax, Docker Buildx, multi-platform image building, rootless mode, and deployment strategies for optimizing container image creation.
