hpfeeds is a lightweight authenticated publish-subscribe protocol. It has a simple wire-format so that everyone is able to subscribe to the feeds with their favorite language in almost no time. Different feeds are separated by channels and support arbitrary binary payloads. This means that the channel users decide the structure of data. It is common to pass JSON over hpfeeds.
This project aims to deliver a modern python 3 compatible broker written on top of asyncio as well as a python 3 compatible client.
To use the client you need to install it in your python environment with
pip install hpfeeds3
The core client does not have any dependencies. You can install the broker dependencies with pip too:
pip install hpfeeds3[broker]
You can also run a broker with Docker:
docker run -p "0.0.0.0:20000:20000" -p "0.0.0.0:9431:9431" jc2k/hpfeeds3-broker:latest
It will store access keys in an sqlite database in
sqlite client installed in the container for managing access. You should make sure
/app/var is a volume. Your clients can connect to port
20000, and prometheus can connect on port
