Creating parameter context for flow definitions

When you build data flows in your NiFi development environment, you create parameter contexts to store configurable values that can vary between environments. Assigning a parameter context to your process group helps you deploy the same flow with different connection strings, credentials, or other settings.

As you are building your data flow in your NiFi development environment, follow these steps to create a parameter context, add parameters to it, and assign the new context to your process group:

Select Parameter Contexts from the Global menu of the NiFi UI.
In the NiFi Parameter Contexts dialog, click the (+) button to create a new parameter context.
Add a name for your parameter context.
Select the Parameters tab to add the parameters you need for configuring your data flow components.
Click Apply to save the parameter context.
To assign the parameter context to your process group, click Configure from the process group context menu and select the parameter context in the Process Group Parameter Context drop-down menu.

note
To add parameters to an existing parameter context, open the Parameter Contexts dialog from the Global menu and click the (Pencil) button in the row of the chosen parameter context. You can also add new parameters to the parameter context when you are configuring the components in your data flow. For more information about parameters and parameter contexts, see the Apache NiFi User Guide.
