Она проектировалась таким образом, чтобы быть простой в использовании и облегчить любому разработчику интеграцию других компонентов с **FastAPI**.

## Что такое "Dependency Injection" (инъекция зависимости)

  istioctl x check-inject deployment/details-v1

  # Check the injection status of a pod under a deployment in namespace test
  istioctl x check-inject deployment/details-v1 -n test

  # Check the injection status of label pairs in a specific namespace before actual injection 
  istioctl x check-inject -n test -l app=helloworld,version=v1

Es ist so konzipiert, sehr einfach zu verwenden zu sein und es jedem Entwickler sehr leicht zu machen, andere Komponenten mit **FastAPI** zu integrieren.
