I’ve figure it out.
just export the NEW_RELIC_CONFIG_FILE as enviroment variable via dokku, and do not add it to the Procfile. In may case ticker is the name of the app
dokku config:set ticker NEW_RELIC_CONFIG_FILE=newrelic.ini
and then procfile is
newrelic-admin run-program gunicorn config.wsgi:application
