Is there a way to configure the app while running it as a docker image?

Using Streamlit
1

Hi all,

I have built an application with streamlit, which requires downloading zipped files of large outputs (500MB-1GB). I tried changing the attribute maxMessageSize to 1000 in config.toml.

The structure of the app is as follows:

├── data/ 
├── Dockerfile 
├── README.md
├── requirements.txt 
├── src/
└──streamlit
    └── config.toml

After spending some time browsing the discussions, this was the docker file I created:

FROM python:3.8.5 
WORKDIR /app
COPY requirements.txt . 

RUN pip install --upgrade pip 
RUN pip install --no-cache-dir -r requirements.txt  
RUN bash -c 'echo -e "\
[server]\n\
enableCORS = false\n\
" > .streamlit/config.toml'
 
EXPOSE 8501 
ENV LC_ALL=C.UTF-8
ENV LANG=C.UTF-8 

COPY /data/ ./data/
ENTRYPOINT ["streamlit", "run"]
CMD ["/app/src/app.py"]

However, if the zipped file size is more than 200 MB, It throws off an error maxMessageSize exceeds 200 MB. Could anyone help me out with this?

Thanks in advance,
Apologies if this question has been previously asked, as I could not find any workaround to this.

The folder name should be .streamlit and not streamlit without a dot.

Hi,
Thank you for replying back.
I changed the name of the folder to .streamlit. However, I am facing another error.
