2.5. AdminNetworkPolicy 문제 해결

2.5.1. ANP 생성 확인
링크 복사

AdminNetworkPolicy (ANP)와 BaselineAdminNetworkPolicy (BANP)가 올바르게 생성되었는지 확인하려면 다음 명령의 상태 출력을 확인하세요. oc describe anp 또는 oc describe banp .

좋은 상태는 OVN DB 플러밍이 성공적이고 SetupSucceeded 임을 나타냅니다.

실패한 정책의 문제를 해결하는 데 도움이 되는 nbctl 명령에 대한 자세한 내용은 다음 섹션을 참조하세요.

2.5.1.1. ANP 및 BANP에 nbctl 명령 사용
링크 복사

실패한 설정에 대한 문제를 해결하려면 ACL , AdressSet , Port_Group을 포함한 OVN Northbound 데이터베이스(nbdb) 객체를 살펴보는 것부터 시작하세요. nbdb를 보려면 해당 노드의 포드 내부에 있어야 해당 노드의 데이터베이스에 있는 객체를 볼 수 있습니다.

사전 요구 사항

  • cluster-admin 역할의 사용자로 클러스터에 액세스할 수 있어야 합니다.
  • OpenShift CLI(oc)가 설치되어 있습니다.
참고

클러스터에서 ovn nbctl 명령을 실행하려면 해당 노드의 `nbdb`에서 원격 셸을 열어야 합니다.

다음 정책은 출력을 생성하는 데 사용되었습니다.

    참고

    수신 및 송신 출력은 ACL의 정책 논리를 보여줍니다. 예를 들어, 패킷이 제공된 일치 항목 과 일치할 때마다 작업이 수행됩니다.

    1. 다음 명령을 실행하여 규칙에 대한 특정 ACL을 조사합니다. 

      $ ovn-nbctl find ACL 'external_ids{>=}{"k8s.ovn.org/owner-type"=AdminNetworkPolicy,direction=Ingress,"k8s.ovn.org/name"=cluster-control,gress-index="1"}'
