 You can use the following Dockerfile to build the accumulator:
 
-```
-FROM debian:stable
-RUN apt-get update -y
-RUN apt-get install -y python3
-RUN apt-get install -y python3-pip
-RUN pip install Flask==2.0.2
-RUN pip install paho-mqtt==1.6.1
-COPY . /app
-WORKDIR /app
-ENTRYPOINT [ "python3", "./accumulator-server.py"]
-CMD ["--port", "1028", "--url", "/accumulate", "--host", "0.0.0.0", "-v"]
