# Entwicklungsumgebung mit VS Code, Docker und Dev Containers
|
||||||
|
|
||||||
|
Diese Anleitung beschreibt die Schritte zur Installation von Visual Studio Code, Docker und der Dev-Container-Erweiterung.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Visual Studio Code installieren
|
||||||
|
|
||||||
|
**Download:** [https://code.visualstudio.com/](https://code.visualstudio.com/)
|
||||||
|
|
||||||
|
**Schritte:**
|
||||||
|
1. Webseite öffnen.
|
||||||
|
2. Betriebssystem auswählen.
|
||||||
|
3. Installationsdatei herunterladen.
|
||||||
|
4. Installation ausführen.
|
||||||
|
5. VS Code starten.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Docker installieren
|
||||||
|
|
||||||
|
**Download:** [https://www.docker.com/products/docker-desktop](https://www.docker.com/products/docker-desktop)
|
||||||
|
|
||||||
|
**Schritte:**
|
||||||
|
1. Webseite öffnen.
|
||||||
|
2. Betriebssystem auswählen.
|
||||||
|
3. Docker Desktop herunterladen.
|
||||||
|
4. Installation ausführen.
|
||||||
|
5. Docker starten.
|
||||||
|
6. Überprüfen in Terminal oder Kommandozeile mit:
|
||||||
|
```bash
|
||||||
|
docker --version
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 3. Dev-Container-Erweiterung installieren
|
||||||
|
|
||||||
|
**Schritte:**
|
||||||
|
1. VS Code öffnen.
|
||||||
|
2. Erweiterungsansicht (_Extensions_) öffnen (`Strg+Shift+X`).
|
||||||
|
3. Nach **"Dev Containers"** suchen.
|
||||||
|
4. Erweiterung von Microsoft installieren.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 4. Dev-Container starten
|
||||||
|
|
||||||
|
**Entwicklungsumgebung in Dev-Container öffnen:**
|
||||||
|
1. Repository aus Gitty lokal klonen, z. B. über Terminal oder Git-Client.
|
||||||
|
```bash
|
||||||
|
git clone https://gitty.informatik.hs-mannheim.de/WEB-IB-WS2526/lab-development-ib.git
|
||||||
|
```
|
||||||
|
2. VS Code starten.
|
||||||
|
3. Den geklonten Projektordner über „Datei → Ordner öffnen…“ auswählen.
|
||||||
|
4. Befehlspalette öffnen (`Strg+Shift+P`).
|
||||||
|
5. Folgenden Befehl eingeben:
|
||||||
|
```
|
||||||
|
Dev Containers: Open Folder in Container...
|
||||||
|
```
|
||||||
|
6. Die Container-Umgebung wird automatisch erkannt und gestartet.
|
||||||
|
7. Das Projekt öffnet sich im Container und ist einsatzbereit.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 5. Funktionstest
|
||||||
|
|
||||||
|
1. Wechseln Sie in den Ordner `web/01/demos/``
|
||||||
|
2. Öffnen Sie `HalloWelt.html` im Editor
|
||||||
|
3. Testen Sie die Browser-Preview:
|
||||||
|
1. Klicken Sie auf das Icon rechts oben:
|
||||||
|
```
|
||||||
|
Open Preview
|
||||||
|
```
|
||||||
|
→ es sollte eine Vorschau der geöffneten HTML-Datei erscheinen.
|
||||||
|
4. Testen Sie die Go-Installation:
|
||||||
|
1. Öffnen Sie einen Terminal
|
||||||
|
2. Geben Sie folgenden Befehl ein:
|
||||||
|
```go
|
||||||
|
go version
|
||||||
|
```
|
||||||
|
→ es sollte `go version go1.24.5 linux/arm64` erscheinen
|
||||||
|
|
||||||
|
## Hinweise
|
||||||
|
|
||||||
|
- Docker muss aktiv sein, bevor VS Code mit Containern arbeitet.
|
||||||
|
- Bei Problemen: VS Code und Docker neu starten.
