Envoy Proxy control-plane written in Python

Project description

sovereign

Mission statement

This project implements a JSON control-plane based on the envoy data-plane-api

The purpose of sovereign is to supply downstream envoy proxies with configuration in near-realtime by responding to discovery requests.

Features

  1. Accepts data from source(s) e.g. file, http, custom
  2. (optional) Applies modifications to the received data
  3. Renders the data into a Jinja2 template (or returns a static response)
  4. Serializes the rendered configuration as JSON and returns it to the Envoy proxy

The idea behind this architecture is to enable high-extensibility.
Users can add their own entry point to the package (todo: documentation) which the control-plane will automatically use to retrieve data to be turned into configuration on the fly.
