1. Q1: Check your .dockerignore file in build path, the files or dir you want to copy may be in the ignore file list!
2. Q2: The COPY directive is based on the context in which you are building the image, so be aware of any problems with the directory where you are currently building the image! See: https://docs.docker.com/engine/reference/builder/#copy
