https://wicaksonodiaz.medium.com/setup-pyflink-development-environment-76d8491a9ad7 I would like to set up Flink locally and then build some test applications using PyFlink. I looked at this link but I am not sure how current it is. Any useful links for me to look at? • I wish to run Flink with PyFlink locally in a Docker container. • Ideally, I'd like to have a Python script running that is generating data in real time. I will process that data as an input stream and also create an output stream in PyFlink. I also see this Dockerfile, but it does not use the latest version on Flink? https://apache.googlesource.com/flink-playgrounds/+/HEAD/pyflink-walkthrough/Dockerfile
