* Proper syncing and shutdown logic. Checking for when an informer has fully started can be quite tricky; `kclient` automatically handles it.

Under the `kclient` package, `clienttest` also provides similar interfaces meant for writing unit tests.

*All Istio informer usage should use this library and not operate on Kubernetes informers directly.*

**`krt`** is a very high level wrapper around Kubernetes informers, building on top of `kclient`.

# Webhooks OpenAPI

Existem situações onde você deseja informar os **usuários** da sua API que a sua aplicação pode chamar a aplicação *deles* (enviando uma requisição) com alguns dados, normalmente para **notificar** algum tipo de **evento**.

Isso significa que no lugar do processo normal de seus usuários enviarem requisições para a sua API, é a **sua API** (ou sua aplicação) que poderia **enviar requisições para o sistema deles** (para a API deles, a aplicação deles).
