# Alpine RDP with Openbox & Firefox
|
||||
|
||||
Minimaler Docker-Container basierend auf Alpine Linux mit xrdp, Openbox und Firefox.
|
||||
|
||||
## Voraussetzungen
|
||||
|
||||
- Docker
|
||||
- Docker Compose
|
||||
|
||||
## Konfiguration
|
||||
|
||||
`.env`-Datei anlegen (siehe `.env.example`):
|
||||
|
||||
```env
|
||||
RDP_PASSWORD=Start1234!
|
||||
FIREFOX_URL=https://www.google.de
|
||||
```
|
||||
|
||||
| Variable | Beschreibung |
|
||||
|---|---|
|
||||
| `RDP_PASSWORD` | Passwort fuer den RDP-Benutzer `rdpuser` |
|
||||
| `FIREFOX_URL` | Startseite, die Firefox beim Oeffnen laedt |
|
||||
|
||||
## Starten
|
||||
|
||||
```bash
|
||||
docker compose up -d --build
|
||||
```
|
||||
|
||||
## Verbinden
|
||||
|
||||
Per RDP-Client (z.B. Remmina, mstsc) verbinden:
|
||||
|
||||
- **Host:** `localhost`
|
||||
- **Port:** `3389`
|
||||
- **Benutzer:** `rdpuser`
|
||||
- **Passwort:** wie in `.env` gesetzt
|
||||
|
||||
## Openbox-Menue
|
||||
|
||||
Rechtsklick auf den Desktop oeffnet das Menue:
|
||||
|
||||
- **Firefox** - Browser mit konfigurierter Startseite
|
||||
- **Logoff** - Sitzung beenden
|
||||
|
||||
## Persistenz
|
||||
|
||||
Firefox-Profildaten werden im Ordner `./firefox-data` gespeichert und bleiben bei Container-Neustarts erhalten.
|
||||
|
||||
## Stoppen
|
||||
|
||||
```bash
|
||||
docker compose down
|
||||
```
