For the client, you could do something like:

docker run -v .:/var/www/html -d -p 8889:80 ubuntu/apache2

For the server, you could create a Dockerfile like:

FROM python:3
EXPOSE 8080
RUN pip install flask
COPY . /
CMD [ "python3", "-m" , "flask", "run", "--host=0.0.0.0", "--port=8080"]

Then you build it. And run it.
docker build -t exam_review_py .

docker run -p 8080:8080 -d  exam_review_py
