MAIL_PROVIDER moved to web-app-stalwart without a make docs run, so every generated README still drew Mailu as the email dependency. This is the generator output for the current tree: the root role table and each role cosmos now name Stalwart, Mailu loses its dependents, and Stalwart gains its swarm marker, the Tor dependencies and the 0..0 edges. The hand-written cosmos of svc-net-tor-smtp gives way to the generated one, which no longer shows the SOCKS5 hop through svc-net-tor because the role does not declare that dependency.

Prometheus
Description
Prometheus is an open-source systems monitoring and alerting toolkit that collects and stores time-series metrics and provides a powerful query language (PromQL).
Overview
This role deploys Prometheus as part of the Infinito.Nexus stack using Docker Compose. It exposes the Prometheus web UI at prometheus.<domain> and protects it with SSO via Keycloak using oauth2-proxy. Universal logout is integrated for session termination.
Cosmos
The diagram places Prometheus 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
- Time-series metrics: Collects and stores time-series data from configured targets.
- PromQL interface: Query and explore metrics via the Prometheus web UI.
- SSO authentication: Access is protected by Keycloak via oauth2-proxy.
- Universal logout: Integrated session termination across the stack.
Quick Setup
Development
Clone, set up the workstation, and deploy Prometheus onto the local stack:
git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-app-prometheus full_cycle=false
Production
Run the published image to provision the inventory and deploy Prometheus to a managed server (the mounted volume persists the inventory):
APP=web-app-prometheus
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 admits only the Prometheus administrator RBAC group through the oauth2-proxy gate, so the biber persona is denied before it ever reaches a Prometheus page: templates/playwright.env.j2 declares PERSONA_BIBER_BLOCKED=true. That denial is not lost coverage — this role's own spec asserts it for every consumer, together with the admin reach and scrape-target parity checks.
The administrator persona is blocked only when services.sso.enabled is false: without the co-deployed Keycloak there is no proxy in front of Prometheus, hence no login round-trip and no logout control to drive. The guest persona and the baseline reachability assertions run unconditionally.
