Kevin Veen-Birkenbach 4ae3cee36c web-svc-logout: merge logout domains into CSP connect-src and refactor task flow
• Add tasks/01_core.yml to set applications[application_id].server.csp.whitelist['connect-src'] = LOGOUT_CONNECT_SRC_NEW.

• Switch tasks/main.yml to include 01_core.yml (run-once guard preserved).

• Update templates/env.j2 to emit LOGOUT_DOMAINS as a comma-separated list.

• Rework vars/main.yml: compute LOGOUT_DOMAINS, derive LOGOUT_ORIGINS with WEB_PROTOCOL, read connect-src via the get_app_conf filter, and merge/dedupe (unique).

Rationale: ensure CSP allows cross-domain logout requests for all configured services.

web-svc-logout

This folder contains an Ansible role to deploy and configure the Universal Logout Service.

Description

This role sets up the universal logout proxy service, a Dockerized Python Flask container that coordinates logout requests across multiple OIDC-integrated applications. It also configures the necessary Nginx proxy snippets and environment variables to enable unified logout flows.

It solves the common challenge of logging a user out from all connected apps with a single action, especially in environments where apps live on multiple subdomains and use OIDC authentication.

Overview

  • Deploys the universal logout service container based on the official universal-logout GitHub repository.
  • Configures the logout domains dynamically based on application inventory and features using custom Ansible filters.
  • Provides an Nginx /logout proxy configuration snippet that handles CORS and forwards logout requests to the logout service.
  • Supplies a user-friendly logout conductor UI that requests logout on all configured domains and shows live status.
  • Designed to be used as the Front Channel Logout URL for Keycloak or other OpenID Connect providers, enabling a seamless, service-spanning logout experience.

Features

  • Automatic discovery of logout domains from applications with the features.logout flag enabled.
  • Centralized logout proxy that clears cookies and sessions across all configured subdomains.
  • Status page with live feedback on logout progress for each domain.
  • Built-in support for Docker Compose deployment and integration with the Infinito.Nexus ecosystem.
  • Includes security-conscious headers (CORS, CSP) for smooth cross-domain logout operations.
