- When a CNI plugin returns dual-stack pod IPs, kubelet will now try to respect the
  "primary IP family" of the cluster by picking a primary pod IP of the same family
  as the (primary) node IP, rather than assuming that the CNI plugin returned the IPs
  in the order the administrator wanted (since some CNI plugins don't allow

   *  * The second race is between plan2 and plan3, with a 250 ms head start for plan2.
   *
   * We get plan0 and plan1 from the route planner.
   * We get plan2 as a follow-up to plan1, typically retry the same IP but different TLS.
   * We get plan3 as a retry of plan0, which was canceled when it lost the race.
   *
   * This test confirms that we prefer to do the TLS follow-up (plan2) before the TCP retry (plan3).

하지만 구니콘은 **프로세스 관리자**역할을 하고 사용자에게 특정 **워커 프로세스 클래스**를 알려줍니다. 그런 다음 구니콘은 해당 클래스를 사용하여 하나 이상의 **워커 프로세스**를 시작합니다.

그리고 **유비콘**은 **구니콘과 호환되는 워커 클래스**가 있습니다.

이 조합을 사용하여 구니콘은 **프로세스 관리자** 역할을 하며 **포트**와 **IP**를 관찰하고, **유비콘 클래스**를 실행하는 워커 프로세스로 통신 정보를 **전송**합니다.

그리고 나서 구니콘과 호환되는 **유비콘 워커** 클래스는 구니콘이 보낸 데이터를 FastAPI에서 사용하기 위한 ASGI 표준으로 변환하는 일을 담당합니다.
