Docker 映像构建失败。 Jupyter 命令“nbconvert”找不到 ipython notebook

Question

I have created a Dockerfile with the purpose of executing a Jupyter notebook inside Docker. It looks like the following

FROM ubuntu:latest

RUN apt-get update && apt-get install -y python3 \
    python3-pip

RUN pip3 install jupyter

WORKDIR /home/me/JupyterOneClick/
RUN pwd

RUN jupyter nbconvert --to python Hello.ipynb
RUN python Hello.py
#CMD ["python","Hello.py"]

But, i am given an error when building this image (docker build -t jupyter:latest .)

Step 6 converts the jupyter notebook to a python file, and step 7 executes that python file.

Step 6/7 : RUN jupyter nbconvert --to python Hello.ipynb ---> Running in 8516a27588f6 [NbConvertApp] WARNING | pattern 'Hello.ipynb' matched no files This application is used to convert notebook files (*.ipynb) to various other formats.

The jupyter notebook is stored in /home/me/JupyterOneClick.

At this point, the build process stops.

I also tried to move step 6 and 7 into a shell script, and run the script from Dockerfile, through which i am able to build the image, but cannot run it, as it cannot find the shell script.

The command '/bin/sh -c chmod +x ./script.sh' returned a non-zero code: 1

Can anyone tell me how do i fix this? I am a beginner, but from what i can understand, RUN creates a new temporary container because of which it is not able to find the file.

For anyone who is wondering, i am not using kubeflow or JupyterHub as they allow for a new development enviromnment, and i have to deploy an existing notebook.

Im not an expert but it seems like you forgot the copy statement. Use COPY ./Hello.ipynb /Hello.ipynb and instead of -- to python you should use -- to script
