Project description

Summary

An application framework with built-in drivers (Controllers), data holders (Sources) and config parsers (Rules). Also includes a web interface for configuration and troubleshooting.

Features

  • Abstract base classes for creating custom controllers, sources and rules
  • The configuration is done using configparser with extended interpolation
  • Start a new netdef project with cookiecutter or make-project. Templates available at https://bitbucket.org/fholmer/cookiecutter-netdef.
  • Built-in Controllers:
    • OpcUa server / client (freeopcua)
    • TcpModbus server / client (pymodbus)
    • icmp ping / url ping
    • XmlRpc client
    • trigger events by using crontab format (crontab)
    • disk, memory and CPU monitoring (psutil)
    • MQTT client (using a simple messaging format called DataAccess) (paho-mqtt)
    • Simple RESTJson client
  • Built-in Rules:
    • Generic CSV config parser
    • Generic INI config parser
    • Generic Yaml config parser
  • Built-in application engines:
    • threaded engine with stdout/stderr only
    • threaded engine with web-interface (webadmin)
    • serve webadmin behind nginx reverse proxy

Use Cases

Netdef is useful if you want to create a middleware that can translate a protocol into a completely different protocol or data format into a completely different data format.

Getting started

First install make-project:

$ python3 -m pip --user install make

Create your first application:

$ python3 -m make project gl:fholmer/cookiecutter-netdef/cookiecutter-minimal-app First-App

Setup your application:

$ cd your-application
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -r requirements-dev.txt
$ pip install -r requirements.txt
