The post explains how to structure Dockerfile instructions from least to most frequently changed to maximize cache reuse, and how to use multi-stage builds to produce lean final images that exclude source code and build tools. Concrete examples are provided for both .NET and Node.js applications, covering dependency installation, compilation, and artifact packaging steps. ## Full article daily.dev links to this article rather than hosting it.
