Where do we get the list of environment variable for NiFi Docker

I’m a beginner in NiFi setup. I’m planning to start a NiFi cluster on Kubernetes. In normal installation, I saw that, we can change the NiFi configurations under the file ‘nifi.properties’. But, when it comes to docker image, I also saw that we can change that by using environment variables. In most of the cases, the properties mentioned in the nifi.properties file can be easily converted into its equivalent environment variable.

Eg:
nifi.web.http.host <=> NIFI_WEB_HTTP_HOST

But in some cases, the environment variable is different. Eg:

nifi.zookeeper.connect.string != NIFI_ZK_CONNECT_STRING

From where do we get the full list of NiFi environment variable for Docker image. Any help like links or directions is very much appreciated.

    You need to look into the documentation (or the source code) of the NiFi docker images your are using. For example agturley/nifi and apache/nifi.

    When you enter the docker container you can see secure.sh and start.sh under the path /opt/nifi/scripts. These are the scripts that make all prop_replace
