Kubernetes Misconfiguration: NamespaceLifecycle Enforcement Disabled

Abstract
O controlador de admissão NamespaceLifecycle em um servidor da API Kubernetes está desativado.
Explanation
A exclusão do namespace Kubernetes remove todos os objetos desse namespace, incluindo pods e serviços. O controlador de admissão NamespaceLifecycle mantém a integridade dos sistemas Kubernetes de duas maneiras. Primeiro, ele evita que objetos sejam criados em namespaces inexistentes ou em namespaces que estão sendo encerrados. Em segundo lugar, evita que os namespaces reservados do sistema, que contêm serviços essenciais do Kubernetes, sejam excluídos.

O controlador de admissão NamespaceLifecycle é ativado por padrão, mas o comando para iniciar o servidor da API Kubernetes o desativou com o sinalizador --disable-admission-plugin.

Exemplo 1: A configuração a seguir inicia um servidor da API Kubernetes. A presença do NamespaceLifecycle incluído no sinalizador --disable-admission-plugins desativa o controlador de admissão NamespaceLifecycle.
