# A VPP Configuration Utility
This tool reads a configuration file, checks it for syntax and semantic correctness, and then
reconciles a running [VPP](https://fd.io/) 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 OpenBSD and Debian.
```
sudo pip3 install argparse
sudo pip3 install yamale
sudo pip3 install pyyaml
sudo pip3 install netaddr
sudo pip3 install ipaddress
sudo pip3 install pyinstaller
sudo pip3 install black
sudo pip3 install pylint
## Ensure all unittests pass.
./tests.py -d -t unittest/yaml/*.yaml
## Build the tool
pyinstaller vppcfg.spec --onefile
dist/vppcfg -h
```
## Running
```
usage: vppcfg [-h] [-d] [-q] [-f] {check,dump,plan,apply} ...
positional arguments:
{check,dump,plan,apply}
check check given YAML config for validity (no VPP)
dump dump current running VPP configuration (VPP readonly)
plan plan changes from current VPP dataplane to target config (VPP readonly)
apply apply changes from current VPP dataplane to target config
optional arguments:
-h, --help show this help message and exit
-d, --debug enable debug logging, default False
-q, --quiet be quiet (only warnings/errors), default False
-f, --force force progress despite warnings, default False
Please see vppcfg <command> -h for per-command arguments
```
