The Production block never set one. inventory provision writes only
ansible_connection for a local host, so DOMAIN_PRIMARY stayed at the
group_vars default of infinito.localhost and the deployment served a zone its
own resolver knows nothing about. CoreDNS templates answers for
INFINITO_DOMAIN_RE and nothing else, so every lookup of the deployment's own
name came back NXDOMAIN.
Mastodon is where that surfaced. tootctl accounts create validates the address
through EmailMxValidator, which resolves MX and then, for the domain itself,
A and AAAA. All six queries returned NXDOMAIN in run 33574056480, the
validator recorded email :unreachable, and the admin account was never created.
Only the guide rows were affected: the matrix rows write
DOMAIN_PRIMARY: "{{ lookup('env', 'INFINITO_DOMAIN') }}" into their host_vars
and resolve fine.
The template now carries DOMAIN=<your-domain> in both the host and the
container form and threads it into --vars, with the container form passing it
through the docker run boundary as well. The two guide runners substitute it
the way they already substitute the SSH key, so the replay deploys under
INFINITO_DOMAIN like every other CI deploy. compose_deploy.sh moves its env
load ahead of the substitutions to have the value; host_deploy.sh had no env
load at all.
A production reader is asked for a domain now instead of silently inheriting
infinito.localhost, which no real deployment wants either. The shipped default
keeps its value: sys-svc-nss documents that *.localhost resolves through the
myhostname NSS module without any zone, and host-side tasks lean on it.

Universal 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
/logoutproxy 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.
Cosmos
The diagram places Universal Logout 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
- Automatic discovery of logout domains from applications with the
features.logoutflag 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.
Quick Setup
Development
Clone, set up the workstation, and deploy Universal Logout onto the local stack:
git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-svc-logout full_cycle=false
Production
Run the published image to provision the inventory and deploy Universal Logout to a managed server (the mounted volume persists the inventory):
APP=web-svc-logout
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
docker run --rm -it \
-v "$PWD/inventories:/etc/infinito.nexus/inventories" \
-e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
ghcr.io/infinito-nexus/core/debian bash -c '
INVENTORY=/etc/infinito.nexus/inventories/production
infinito administration inventory provision "$INVENTORY" \
--inventory-file "$INVENTORY/devices.yml" \
--host "$HOST" \
--include "$APP" \
--vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
--password-file "$INVENTORY/.password" \
--diff -vv'

Persona contract opt-outs
meta/services.yml declares no sso service, so this role is never registered as a Keycloak client. Its only HTTP surface is the anonymous logout conductor and the /logout endpoints proxied by templates/logout-proxy.conf.j2 — there is no login form, no account and no session to end.
templates/playwright.env.j2 therefore declares PERSONA_BIBER_BLOCKED=true and PERSONA_ADMINISTRATOR_BLOCKED=true. The service's real coverage is per consumer: files/playwright/playwright.spec.js parameterises the injected logout JS over roles_with_service('logout').
