> I have a slight improvement to Environment variables that the NiFI docker system uses to bootstrap its nifi.properties files
> There are times, when learning NiFi, that I want to stop and start NiFi with debugging on. If NiFi was running inside a Docker container it was hard.
> What I did was I created a new environment variable within the NiFi bootstrapping system it uses to start itself up inside a docker container. I have documented all NiFI environment variables here.
> [https://github.com/dprophet/nifi/blob/master/nifi-docker/dockerhub/CONFIGURATION.md]
> I just pushed some code for review
> https://github.com/dprophet/nifi/commit/ea31ac6bd8f00944166e3e230af2040636c0505c
> What I did was introduce a new environment variable
> NIFI_DEBUG
> And in file
> https://github.com/apache/nifi/blob/master/nifi-docker/dockerhub/sh/start.sh
> I added
> if [[ -n $NIFI_DEBUG ]] ; then
>  . "${scripts_dir}/update_logback.sh"
> fi
> Basically what it does, if the NIFI_DEBUG is set
> Example:
> NIFI_DEBUG="org.apache.nifi.web.security=TRACE,org.apache.nifi.authorization=DEBUG,org.apache.nifi.web.api.config=TRACE"
> It updates the 
> ${NIFI_HOME}/conf/logback.xml
> File to enable the debugging modes of NiFi
> This is a very fast mechanism to restart NiFi with debugging turned on. Very developer and workflow friendly.
> If of interest I will give a pull request.
> What about the documentation I created?
