FROM: Define the base image, such as ubuntu or debian, used to start the build process. BUILDPLATFORM is part of a set of automatically defined (global scope) build arguments that you can use. Whereas people, those don’t know about Docker, it is a platform to create and run the virtual container to install the various application using the Docker Images. The answer is no, and instead of writing a constant platform value into our Dockerfile we should use a variable instead, FROM -platformBUILDPLATFORM debian.
