I am trying to build a docker image from a shell script called "noreward-rl.sh" and a text file "requirements.txt" by running it in the build process. My question is in the last line.
code:
FROM ubuntu
ENV DEBIAN_FRONTEND=noninteractive
ENV TZ=America/St_Johns
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends curl python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb ffmpeg xorg-dev python-opengl libboost-all-dev libsdl2-dev swig python3-dev python3-venv make golang libjpeg-turbo8-dev gcc wget unzip git fceux virtualenv tmux
COPY . /
RUN mkdir n && pwd && ls && bash /noreward-rl.sh n
CMD python n/src/train.py -e mario
output:
l@l-Lenovo-Rescuer-15ISK:/media/l/DATA/i$ sudo docker build .

bash: /noreward-rl.sh: No such file or directory
The command '/bin/sh -c mkdir n && pwd && ls && bash /noreward-rl.sh n' returned a non-zero code: 127
Why is it telling me that noreward-rl.sh doesn't exist while "ls" command shows me that it is in the current directory? Why is there an extra space in the filename in output of ls command?
UPDATE: I changed "noreward-rl.sh" to "n.sh" and it works now. But I still wonder why it did that?
new code:
