I thought about porting the script, but instead i put it in a docker container.

Here's the Dockerfile

FROM ubuntu
ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Europe/Berlin
RUN apt-get update && apt-get install -y software-properties-common curl build-essential libleveldb-dev && add-apt-repository universe
RUN apt-get update && apt-get install -y python2 python-dev
RUN curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output /get-pip.py
RUN python2 /get-pip.py
RUN pip2 install plyvel base58

CMD ["python2", "/data/btcposbal2csv.py", "/chainstate", "/data/btcbal.csv"

mount chainstate and script directory according to last line in dockerfile. output goes to the directory of the python script in the example.

Hello, yes, the script does not work in python3. It is clearly stated, that it needs python2.

The docker is good idea.
