Two Q's regarding the docker container; 1. Why the Debian version instead of Alpine? Was it compatibility with external stuff? I can confirm 2.0.0-M1 works fine with the alpine version of liberica-jdk on at least basic flows, with python enabled. It'll save disk space. I love Debian but Alpine is king of containers!
2. If we shift the repository folders out of NIFI_HOME per the regular best practice doco, then a persistent docker volume could easily be used to house these, making upgrades painless. I guess the flow.json, keystores and configs could move too. Kind regards, Matt
