This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints.

Mas esse exemplo ainda é valido e mostra como interagir com os componentes internos.

Também podemos usar essa mesma abordagem para acessar o corpo da requisição em um manipulador de exceção.

Tudo que precisamos fazer é manipular a requisição dentro de um bloco `try`/`except`:
