### 3. Tekton Dashboard zichtbaar maken (UI)

De pipeline moet kunnen pushen naar jouw fork. Maak een GitHub PAT aan met `repo`-scope en voer dan uit:
|
||||
Maak een aparte Tekton Dashboard app, met Ingress zodat je PipelineRuns in de browser ziet.

### 4. Git-credentials instellen
|
||||
|
||||
Dit is een verplichte stap vóór je de PipelineRun triggert.
|
||||
Zonder `git-credentials` secret faalt de `clone` task direct.
|
||||
|
||||
De pipeline moet kunnen pushen naar jouw fork.
|
||||
Maak een GitHub PAT aan met `repo`-scope en voer dan uit:
|
||||
|
||||
```bash
|
||||
./scripts/vm/set-git-credentials.sh <jouw-github-gebruikersnaam> <jouw-pat>
