How can you ensure that some files will be ignored by a build process and won't be copied as part of COPY instruction that is defined in a Dockerfile?

Answer
To exclude files not relevant to the build (without restructuring your source repository) use a .dockerignore file. This file supports exclusion patterns similar to .gitignore files. For information on creating one, see the .dockerignore file.
