Re: Regarding Nifi packaging and deployment
The NiFi Expression language (EL) can also use system user environment variables as well as NiFI JVM properties as input. So you could create templates that have EL statements that reference these environment variables which would allow each system running the same dataflow to pull in different values. NiFI JVM properties would be added to the bootstrap.conf file in your NiFi installation. While system environment variables are set at the OS level. There is an order of preference is NiFi will first search for FlowFIle Attributes matching the defined subject/key name, then system environment variables, and last JVM environment variables.

Re: Regarding Nifi packaging and deployment
Shweta, The primary mechanism is flow templates [1]. They do have some important limitations today though that you'll want to understand. First, some properties are sensitive, like passwords, and thus are not included in the templates so you'll have to reenter them when you apply the template in the new environment. Second, there are at times properties you'd want to have different values for in different environments. We need to provide a property/env variable mapping mechanism. Both of these we intend to address but neither are presently actively being worked as far as I'm aware of.

Regarding Nifi packaging and deployment
Hi all, I'm new to Nifi. I have created some sample flows. I want to know how can I package and deploy the same from development environment to testing environment or do I need to recreate the entire data flow again in different environment.
