Jakub Czaplicki created BEAM-12910:
--------------------------------------
Summary: A ready docker image for running Beam with Kafka
Key: BEAM-12910
URL: https://issues.apache.org/jira/browse/BEAM-12910
Project: Beam
Issue Type: Wish
Components: examples-python
Environment: slim python docker image
Reporter: Jakub Czaplicki
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 beamfrom apache_beam.options.pipeline_options import
PipelineOptionsdef 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
INFO:root:Missing pipeline option (runner). Executing pipeline using the
default runner: DirectRunner.

See 'docker run --help'.
So I then tried the ```{{apache/beam_python3.8_sdk:latest``` image, but this
led me to even more problems:

{{My wish is to put a simple HOWTO instructions somewhere together with a
