exposing a nifi property as env variable

manishg — Fri, 12 Jan 2024 07:32:05 GMT

Is this the correct way of exposing a nifi property as env variable(in start.sh):

prop_replace 'nifi.web.http.port'      "${NIFI_WEB_HTTP_PORT:-8080}"

I expect it to expose nifi.web.http.port as NIFI_WEB_HTTP_PORT, and also setting it to default value of 8080.

I am not clear on what you are trying to accomplish here.
What is the use case?
What is your NiFi version?
What is your OS?

NiFi does not have a "start.sh" script. Are you talking about the "nifi.sh" script.

Perhaps there are just some important details I am missing here.
also not sure why you would want to change the nifi..web.http.port configuration property in the nifi.properties file to a variable. These properties are all read during startup of NiFi and evaluating NiFi variables is does not happen during NiFi startup. Nor does NiFi support defining NiFi variables in the nifi.properties file.
