Health CSP Crawler

Description

This Ansible role automates the validation of Content Security Policy (CSP) enforcement for all configured domains by crawling them using a CSP Checker.

Overview

Designed for Archlinux systems, this role periodically checks whether web resources (JavaScript, fonts, images, etc.) are blocked by CSP headers. It integrates Python and Node.js tooling and installs a systemd service with timer support.

Cosmos

The diagram places Health CSP Crawler in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Features

  • CSP Resource Validation: Uses Puppeteer to simulate browser requests and detect blocked resources.

  • Domain Extraction: Parses all .conf files in the NGINX config folder to determine the list of domains to check.

  • Automated Execution: Registers a systemd service and timer for recurring health checks.

  • Error Notification: Integrates with sys-ctl-alm-compose for alerting on failure.

  • Ignore List Support: Optional variable to suppress network block reports from specific external domains.

Configuration

Variables

  • HEALTH_CSP_IGNORE_NETWORK_BLOCKS_FROM (list, default: [])
    Optional list of domains whose network block failures (e.g., ORB) should be ignored during CSP checks.

Example:

HEALTH_CSP_IGNORE_NETWORK_BLOCKS_FROM:
  - pxscdn.com
  - cdn.example.org

This will run the CSP checker with:

checkcsp start --short --ignore-network-blocks-from pxscdn.com -- cdn.example.org <domains...>

Systemd Integration

The role configures a systemd service and timer which executes the CSP crawler periodically against all NGINX domains.
