running two separate Python-Flask api via a single docker file

Question

I want to run two different python api files running on different ports via a single container.

My docker file looks like:

FROM python:3.7-slim-buster

RUN apt-get update && apt-get install -y libgtk2.0-dev cmake libpoppler-cpp-dev poppler-utils tesseract-ocr

WORKDIR /app

COPY requirements.txt ./

RUN pip install --no-cache-dir -r requirements.txt 



COPY . .

RUN chmod a+x run.sh

CMD ["./run.sh"]

And the .sh file looks like:

#!/bin/bash

exec python3 /app1/numberToWord.py &
exec python3 /app2/dollarToGbp.py &

While the docker build is a success without any error, the docker run doesn't throw any error and exits the command line. I'm curios to know where is it failing, any insight is highly appreciated.

Answer 1

Try using nohup to ignore hangup signal

Ex:

#!/bin/bash

nohup python3 /app1/numberToWord.py &
nohup python3 /app2/dollarToGbp.py &
