With more and more applications being containerized with Docker, creating efficient and secure images is crucial. Multi-stage builds in Docker provide a powerful way to optimize container images for performance, security, and efficiency. In this talk, we'll explore the benefits of multi-stage builds and learn how developers can use them to reduce the size and complexity of their images by separating the built environment from the runtime environment.

We'll cover best practices for organizing your Dockerfile, optimizing the build process with caching and parallelism, and using multi-stage builds for language-specific applications. Finally, we'll showcase real-world examples of multi-stage builds, including creating custom images for Go.
