A ready docker image for running Beam with Kafka

I have hit an issue that either shows that I am doing something wrong, or I haven't found a good docker image.

I am trying to run such a piece of Python 3.8 code:

import apache_beam as beam

from apache_beam.options.pipeline_options{{ import PipelineOptions}}

def run():
    options = PipelineOptions(["--runner=DirectRunner"])

    with beam.Pipeline(options=options) as p:
        p | beam.Create([1, 2, 3]) | beam.Map(lambda x: x-1) | beam.Map(print)

if _name_ == "_main_":
    run()}}

Running it locally works fine. However I noticed that on runtime the beam part downloads and runs a docker container. So running Beam with Kafka in Docker container requires adding Java and Docker (running docker inside docker container) :

Dockerfile (simplified): 

FROM python:3.8.12-slim
{{ RUN apt update}}
{{ RUN apt install -y wget curl unzip git}}COPY ./ /root/data_collector/
{{ WORKDIR /root/data_collector}}
{{ RUN python3 -m pip install --upgrade pip}}
{{ RUN python3 -m pip install -r beam/requirements/requirements.txt}}
{{ CMD python3 beam/data_aggregation.py}}

Running docker:

% docker run --network=kafka --name=beam beam

So I then tried the  apache/beam_python3.8_sdk:latest image, but this led me to even more problems: https://stackoverflow.com/questions/69195731/dockerized-apache-beam-returns-no-id-provided

My wish is to put a simple HOWTO instructions somewhere together with a docker image for running Beam with Kafka.
