Manish, Maybe not available as a variable necessarily (this will come later), but you can apply properties when you deploy your template. Basically, set them directly as part of the deployment. Take a look https://github.com/aperepel/nifi-api-deploy

From “Expression Language Guide”, I know one can use environment variable or JVM system property. Or specify the value for one flow using an update attribute processor near the top of the flow. But is there a way I can have a single property / xml file to have my all the configurations available and each property be available in nifi as a variable? Thanks, Manish
