 # Урок 3.3 — Продвинутые техники мутации и переменные
 
+## Источники переменных
+
+Kyverno поддерживает несколько источников переменных:
+
+1. **Данные запроса** — `request.object`, `request.operation`, `request.userInfo`
+2. **Данные из API** — через `context.apiCall`
+3. **Данные из ConfigMap** — через `context.configMap`
+4. **Глобальные переменные** — через `context.globalReference`
+5. **Генерируемые данные** — `{{ random('[0-9]{6}') }}`, `{{ time_now() }}`
+
