+## Problemstellung
+### Keine Reproduzierbarkeit beim Base Image
+- Base Image ist nicht reproduzierbar
+- Base Image ist nicht verifizierbar
+
+#### Lösung
+- Base Image selbst bauen
+- Base Image verifizieren
+- Base Image Version pinning
+
+### Keine Reproduzierbarkeit beim Build
+- Build ist nicht reproduzierbar
+- Build ist nicht verifizierbar
+
+#### Lösung
+- Build verifizieren
+- Build Version pinning (package-lock.json, Gemfile.lock, requirements.txt)
+
+### Layering
+- Falsche Reihenfolge der Layer
+
+#### Lösung
+- Dateien mit häufigen Änderungen nach unten
+
+### Root User
