Docker image doesn't has "/script" folder #2224
Description
Per Dockerfile, it is copied to "/script" folder.
However bash into the docker container, no "/script" folder there.
Impact: new-user can't follow doc to generate RecordIo files.
Workaround: use the one mounted to /work/
Tried add "RUN mkdir /script" and it also can't work. Have no idea on why.
