NiPyApi

Nifi-Python-Api: A rich Apache NiFi Python Client SDK

Features

Three layers of Python support for working with Apache NiFi:

High-level Demos and example scripts
Mid-level Client SDK for typical complex tasks
Low-level Client SDKs for the full API implementation of NiFi and selected sub-projects

Functionality Highlights:

Detailed documentation of the full SDK at all levels
CRUD wrappers for common task areas like Processor Groups, Processors, Templates, Registry Clients, Registry Buckets, Registry Flows, etc.
Convenience functions for inventory tasks, such as recursively retrieving the entire canvas, or a flat list of all Process Groups
Support for scheduling and purging flows, controller services, and connections
Support for fetching and updating Variable Registries
Support for import/export of Versioned Flows from NiFi-Registry
Docker Compose configurations for testing and deployment
A scripted deployment of an interactive environment, and a secured configuration, for testing and demonstration purposes

Please see the issue register for more information on current development.

Quick Start

There are several scripts to produce demo environments in nipyapi.demo.*

The mid-level functionality is in nipyapi.canvas / nipyapi.security / nipyapi.templates / nipyapi.versioning

You can access the entire API using the low-level SDKs in nipyapi.nifi / nipyapi.registry

The easiest way to install NiPyApi is with pip:

# in bash
pip install nipyapi

You can set the config for your endpoints in the central config file:

# in python
import nipyapi
nipyapi.config.nifi_config.host = 'http://localhost:8080/nifi-api'
nipyapi.config.registry_config.host = 'http://localhost:18080/nifi-registry-api'

Then import a module and execute tasks:

nipyapi.canvas.get_root_pg_id()
>'4d5dcf9a-015e-1000-097e-e505ed0f7fd2'

You can use the Docker demos to create a secured interactive console showing many features:

from nipyapi.demo.secured_console import *
from nipyapi.demo.console import *

You can also explore the scripts to get ideas for how NiPyAPi can be used to automate your environment.
