BlueSkySight

A client to gather vulnerability-related information from Bluesky. The collected data is then sent to the Vulnerability-Lookup API as sightings.

Installation

pipx is an easy way to install and run Python applications in isolated environments. It's easy to install.

$ pipx install BlueSkySight
$ export BLUESKYSIGHT_CONFIG=~/.BlueSkySight/conf.py

The configuration should be defined in a Python file (e.g., ~/.BlueSkySight/conf.py). You must then set an environment variable (BLUESKYSIGHT_CONFIG) with the full path to this file.

You can have a look at this example of configuration.

With Docker

git clone https://github.com/vulnerability-lookup/BlueSkySight
cd BlueSkySight

# Make sure conf.py exists in the project root before running
docker compose up --build
