14장. director Operator를 사용하여 spine-leaf 구성으로 노드 배포
스파인-리프형 네트워킹 아키텍처를 사용하여 노드를 배포하여 사용자 환경 내에서 광범위한 네트워크 토폴로지를 복제합니다. 현재 제한으로 Metal3 에 대한 하나의 프로비저닝 네트워크만 허용됩니다.
14.1. 모든 서브넷을 정의하도록 OpenStackNetConfig 사용자 지정 리소스 생성 또는 업데이트
OpenStackNetConfig 사용자 지정 리소스를 정의하고 오버클라우드 네트워크의 서브넷을 지정합니다. 그러면 director Operator가 구성을 렌더링하고 네트워크 토폴로지를 업데이트하거나 업데이트합니다.
사전 요구 사항
- OpenShift Container Platform 클러스터가 작동하고 director Operator를 올바르게 설치했습니다.
