Answer 1

In your Dockerfile, add a line to copy a custom startup script into the container. For example:

COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

Create a file named entrypoint.sh and add the following content:

#!/bin/bash
python manage.py runserver 0.0.0.0:8443 &

python consumer.py

tail -f /dev/null

In your Dockerfile, use the following CMD instruction:

CMD ["/entrypoint.sh"]
