The COPY instruction will copy new files or directories from <source path> and add them to the file system of the container at the path <destination path>.
It's very similar to the ADD instruction, even the syntax is no different:
COPY <source path or URL> <destination path >
The same rules from ADD apply to COPY: all source paths must be relative to the context of the build. Again the presence of the trailing slash at the end of the source and destination path is important: if it's present, the path will be considered a file; otherwise, it will be treated as a directory.
Of course, as in ADD, you can have multiple source paths. If source or destination paths contain spaces, you will need to wrap them in square brackets:
COPY ["<source ...
