Description
Added VEX walkthrough guide for Docker Hardened Images
The existing DHI documentation covers VEX concepts and scanner integration, but as separate reference topics. Users who want to understand VEX in practice have to piece together the workflow themselves.
This guide shows the full workflow end-to-end against a real image (
dhi.io/python:3.13): scan without VEX to get the raw CVE baseline, fetch the attestation, scan again with VEX applied, then inspect every suppression and the reasoning behind it. Each step shows actual command output so readers can compare what they see against a known reference.The guide covers:
--show-suppressedflag to surface per-CVE justification codesjqqueries against the raw VEX file to read Docker's human-readable reasoning and filter by status (not_affected,under_investigation,affected)The goal is to give readers a working mental model of what VEX does and how to audit it — something a walkthrough can do that reference docs can't.
