COPY [--chown=<user>:<group>] <src>... <dest>
The <src> path must be inside the context of the build; you cannot COPY ../something /something,
because the first step of a docker build is to send the context directory (and subdirectories)
to the docker daemon.
If <src> is a directory, the entire contents of the directory are copied, including filesystem metadata.
!!!!The directory itself is not copied, just its contents.!!!!
