Supercharged Docker Build with BuildKit

Explore the latest advancements in Docker build enabled by the BuildKit project in this 44-minute talk. Discover new additions to the Dockerfile syntax introduced in version 18.09, including techniques for enabling fast incremental builds with cache mounts, securely exposing secrets during the build process, and forwarding SSH to access private repositories. Dive deep into the implementation of these features in external BuildKit frontends running sandboxed in regular containers. Learn how BuildKit's flexibility allows for the addition of new features to the Dockerfile syntax and enables building projects without a Dockerfile through custom frontends. Compare the old builder with BuildKit, understand the internal flow of BuildKit, and explore concepts such as LLB, sources, KPA Gateway, and multiplatform results. Gain practical knowledge through demonstrations and examples of running custom frontends and utilizing the Dockerfile frontend.
