I have a slight improvement to Environment variables that the NiFI docker system uses to bootstrap its nifi.properties files
I documented it under https://issues.apache.org/jira/browse/NIFI-6013 The commit is here. https://github.com/dprophet/nifi/commit/ea31ac6bd8f00944166e3e230af2040636c0505c ***** 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. FYI, some of those environment variables are documented here. https://github.com/apache/nifi/blob/master/nifi-docker/dockerhub/README.md 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 create a JIRA, put the code on a fork, and give a pull request. Erik Anderson Bloomberg
