I met a problem after I run the docker container, it dockerize the streamlit (python) app. It looks the json file cannot load due to permission issue.

PermissionError: [Errno 13] Permission denied: 'inference_data/1234_photo_group.json' Traceback: File "/usr/local/lib/python3.9/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 541, in _run_script exec(code, module.__dict__) File "/app/app.py", line 128, in <module> gen_photo_group(report1_images, map_image_cap_1, "1234") File "/app/utils.py", line 188, in gen_photo_group with open("inference_data/" + report_id + "_photo_group.json", "w") as outfile:

Here is my docker file:

`FROM python:3.9-slim
EXPOSE 8080
RUN apt-get update && apt-get install -y 
    build-essential 
    curl 
    && rm -rf /var/lib/apt/lists/*
WORKDIR /app
COPY requirements.txt ./requirements.txt
COPY ./key.json /secret/key.json
RUN pip3 install -r requirements.txt
COPY . .
CMD streamlit run app.py --server.port=8080 --server.address=0.0.0.0`

Does it mean I need to grant permission in docker file? or other reason cause the permission issue. Thanks.

I tried to change the dockerfile, but it did not work. I need to know how to change the dockerfile to grant the permission or use other method to resolve this issue. Thanks.
