A VPP Configuration Utility

This tool reads a configuration file, checks it for syntax and semantic correctness, and then reconciles a running VPP daemon with its configuration. It is meant to be re-entrant and stateless. The tool connects to the VPP API and creates/removes all of the configuration in a minimally intrusive way.

NOTE This code is under development, and probably won't work well until this note is removed. If you're interested in helping, reach out to <pim at ipng dot ch> to discuss options.

Building

This program expects Python3 and PIP to be installed. It's known to work on Debian Bullseye and Ubuntu Focal/Jammy.

## Install python build dependencies 
$ make install-deps

## Ensure all unittests pass.
$ make test

## Build vppcfg
$ make build

## Install the tool with PIP
$ make install

## To build & install debian packaging
$ make pkg-deb
$ ls -l ../vppcfg_*_amd64.deb
