- If using cgroups v2, then the cgroup aware OOM killer will be enabled for container cgroups via  `memory.oom.group` .  This causes processes within the cgroup to be treated as a unit and killed simultaneously in the event of an OOM kill on any process in the cgroup.

kube-scheduler and kube-controller manager now use SO_REUSEPORT socket option when listening on address defined by --bind-address and --secure-port flags, when running on Unix systems (Windows is NOT supported). This allows to run multiple instances of those processes on a single host with the same configuration, which allows to update/restart them in a graceful way, without causing downtime.

E também depois que a `response` é gerada, antes de retorná-la.

Por exemplo, você pode adicionar um cabeçalho personalizado `X-Process-Time` contendo o tempo em segundos que levou para processar a solicitação e gerar uma resposta:

Apenas um processo no servidor pode se conectar a uma porta em um endereço IP. Poderiam existir outros processos conectados em outras portas desse mesmo endereço IP, mas apenas um para cada combinação de endereço IP e porta.

TLS (HTTPS) usa a porta `443` por padrão. Então essa é a porta que precisamos.

Como apenas um único processo pode se comunicar com essa porta, o processo que faria isso seria o Proxy de Terminação TLS.
