+\title{Service-Portal Architektur}
+\author{schooltech.ch}
+\date{\today}
+
+\begin{document}
+\maketitle
+
+\section{Zielsetzung}
+Ziel ist der Aufbau eines zentralen Login- und Navigations-Portals für mehrere unabhängige Web-Services,
+die in Docker-Containern betrieben werden.  
+Benutzer authentifizieren sich einmal zentral und können anschließend zwischen Services wechseln,
+die jeweils unter eigenen Subdomains bereitgestellt werden.
+
+\section{Architekturübersicht (final)}
+
+\subsection{Domänenstruktur}
+\begin{itemize}
+  \item \texttt{server.schooltech.ch} – Login- und Navigations-Portal (SPA)
+  \item \texttt{<service>.server.schooltech.ch} – einzelne Services (Docker Container)
+\end{itemize}
+
+\subsection{High-Level Architektur}
+\begin{verbatim}
+Internet
+  |
+  | HTTPS (*.server.schooltech.ch)
+  v
+---------------------+
+|  Nginx ReverseProxy |
+|  TLS, Auth, Routing |
+---------------------+
+   |           |
+   |           +--> Service Container (abc)
+   |                abc.server.schooltech.ch
+   |
+   +--> Portal / Auth Service
+        server.schooltech.ch
+\end{verbatim}
+
+\subsection{Zentrale Prinzipien}
+\begin{itemize}
+  \item Ein Einstiegspunkt (Nginx)
+  \item Zentrale Authentifikation (auth\_request)
+  \item Services kennen kein Login
+  \item Keine iFrames, kein Subpath-Rewrite
+  \item Services laufen auf Root-Pfad (\texttt{/})
+\end{itemize}
+
+\section{Authentifikation (Variante A: auth\_request)}
+
+\subsection{Prinzip}
+Nginx prüft jeden Request zu einem Service mittels \texttt{auth\_request} gegen den Auth-Service.
+Der Auth-Service entscheidet ausschließlich anhand der Session (Cookie).
+
+\subsection{Ablauf}
+\begin{enumerate}
+  \item Benutzer loggt sich am Portal ein
+  \item Portal setzt Session-Cookie:
+  \begin{verbatim}
+  Domain=.server.schooltech.ch
+  Secure; HttpOnly; SameSite=None
+  \end{verbatim}
+  \item Benutzer ruft Service-Subdomain auf
+  \item Nginx fragt \texttt{/internal/auth} beim Auth-Service an
+  \item Bei Erfolg: Request wird an Service weitergeleitet
+\end{enumerate}
+
+\subsection{Header-Weitergabe}
+Optional injiziert Nginx folgende Header:
+\begin{itemize}
+  \item \texttt{X-Remote-User}
+  \item \texttt{X-User-Roles}
+\end{itemize}
+
+\section{Nginx Konfiguration}
+
+\subsection{Wildcard Server Block}
+\begin{verbatim}
+server {
+  listen 443 ssl;
+  server_name *.server.schooltech.ch;
+
+  ssl_certificate     /etc/letsencrypt/live/server.schooltech.ch/fullchain.pem;
+  ssl_certificate_key /etc/letsencrypt/live/server.schooltech.ch/privkey.pem;
+
+  location / {
+    auth_request /internal/auth;
+    proxy_pass http://$upstream;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+  }
+
+  location = /internal/auth {
+    proxy_pass http://auth:3000/internal/auth;
+    proxy_pass_request_body off;
+    proxy_set_header Content-Length "";
+    proxy_set_header X-Original-URI $request_uri;
+  }
+}
+\end{verbatim}
+
+\subsection{Upstream Mapping}
+\begin{verbatim}
+map $host $upstream {
+  default                 portal:3000;
+  abc.server.schooltech.ch abc:8080;
+  xyz.server.schooltech.ch xyz:8080;
+}

+\end{verbatim}
+
+\subsection{Portal als Docker Container}
+Das Portal wird als eigener Container betrieben und statisch oder via Node.js ausgeliefert.
+Es besitzt keine direkte Kopplung zu den Services außer über URLs.
+
+\section{Zusammenfassung}
+Diese Architektur ermöglicht:
+\begin{itemize}
+  \item saubere Trennung von Portal und Services
+  \item zentrale Sicherheit
+  \item einfache Erweiterbarkeit
+  \item wartbare Reverse-Proxy-Konfiguration
+\end{itemize}

+Ich habe eine WEbPage hinter einer Firewall. Die besteht aus mehreren Services die in Docker Containern mit jeweils eine Einstiegs-Seite (an einem offenem Port) breitstehen.
+
+Jetzt will ich für Kunden eine Login-Page aufbauen. Auf der Login-Page soll in der Kopfzeile ein transparenter Balken sein, mit User- und Passwort Authentifikation. Wenn der User angemeldet ist sollen in der Kopf-Zeile verschiedene Buttons (für verschiedene Services) erscheinen. Jeder dieser Services soll auf einen Container zeigen, so dass die Kopfzeile als Navigation der Services möglich ist. 
+
+Wenn auf eine der Services gedrückt wird, soll die Kopfzeile zur "kollabieren" und nur noch als "offnebares-bookmark" oder so bereitstehen. Die Haupt-Page soll eben auf diesen Service zeigen.
+
+Ich gehe davon aus, dass dafür 1) eine Login-Site (eventuell mit NodeJS, da ich das kenne) mit Navigation nötig ist, 2) Nginx im Hintergrund die Pages weiterleitet. 
+
+Skizziere erst mal einen Aufbau, bevor ich über Implementationen nachdenke.
