# Authentik — zentraler Homelab-IdP (nexus ADR-0003)
|
||||
#
|
||||
# Creates an unprivileged Debian 12 LXC with nesting enabled that runs the
|
||||
# official Authentik docker-compose stack (server, worker, postgres, redis).
|
||||
#
|
||||
# Automation-friendly by design (nexus-hub K-102):
|
||||
# - bootstrap admin password AND API token are generated headlessly
|
||||
# (-> /root/authentik.credentials) so an agent can apply blueprints via
|
||||
# API without ever touching the UI
|
||||
# - optional dedicated SSH public key for agent access (Claude Code)
|
||||
# - blueprints dir mounted at /opt/authentik/blueprints (compose override)
|
||||
#
|
||||
# Manual steps that remain AFTER this script (by design):
|
||||
# 1. NPMplus: proxy host auth.<domain> -> http://<LXC-IP>:9000
|
||||
# (WebSockets ON; the auth domain is PERMANENT — WebAuthn RP-ID!)
|
||||
# 2. Passkey enrollment of the human admin account
|
||||
#
|
||||

|

# Allgemeiner Gitea-Actions-Runner — instanzweit, OHNE Deploy-Rechte
|
||||
#
|
||||
# Motivation (nexus K-114-Blocker): Der nexus-Runner läuft auf dem
|
||||
# Produktions-LXC und besitzt sudoers-Deploy-Rechte — er darf deshalb NICHT
|
||||
# instanzweit registriert werden (jedes Repo könnte sonst Workflows auf der
|
||||
# Produktionsmaschine ausführen). Dieser LXC ist die saubere Trennung:
|
||||
# - instanzweite Registrierung (Site Administration → Actions → Runners)
|
||||
# - Label "homelab:host" (Deploy-Jobs bleiben auf "nexus")
|
||||
# - KEINE sudoers-Regeln, kein Zugriff auf Produktions-Verzeichnisse
|
||||
# - Docker via Nesting für Wegwerf-Test-Container (z. B. pgvector in CI)
|
||||
#
|
||||
# Sicherheitsmodell: siehe Kopfkommentar in install/runner-install.sh —
|
||||
# instanzweit + docker-Gruppe heißt: jedes Repo der Instanz kann diesen LXC
|
||||
# kontrollieren. Akzeptiert, WEIL er nichts besitzt. Nicht auf privilegierte
|
||||
# LXCs übertragen.
