Each instruction forms a new image layer, optimizing build efficiency through automatic caching. This integration works seamlessly with source control systems, ensuring progressive changes can be efficiently managed. By utilizing <code>ARG</code> instructions—akin to <code>ENV</code> but specified at build-time—you can create highly adaptable builds.</p> <p>For most developers, standard Dockerfile usage is sufficient. However, maintaining base images across multiple environments presents a significant challenge.</p>
