-----------------------------------
Summary: NiFi Docker Environment Variable for enabling debugging
of NiFi inside a Docker container
Key: NIFI-6013
URL: https://issues.apache.org/jira/browse/NIFI-6013
Project: Apache NiFi
Issue Type: Improvement
Components: Docker
Reporter: Erik Anderson
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?
