2장. RHACM을 사용하여 OpenShift Data Foundation Logical Volume Manager Operator 설치

절차

1. OpenShift 인증 정보를 사용하여 RHACM CLI에 로그인합니다.

   자세한 내용은 Kubernetes용 Red Hat Advanced Cluster Management 설치를 참조하십시오.

2. 네임스페이스를 생성합니다.

   # oc create ns lvm-policy-ns

3. 네임스페이스에 정책 YAML을 생성합니다.

   # This policy verifies the installation of the official version of the OpenShift Data Foundation
   # Logical Volume Manager Operator on the managed clusters.
   # If set to "enforce" it installs the operator.
   # Used APIs: OLM, ODF-LVMO #https://github.com/operator-framework/operator-lifecycle-manager
   # https://github.com/red-hat-storage/lvm-operator

4. 다음 명령을 실행합니다.

   이렇게 하면 정책, 배치 규칙 및 Placement Binding 이 생성됩니다. 정책은 네임스페이스 , OperatorGroup ,Subscription, LVMCluster 리소스를 생성합니다. 이렇게 하면 선택 기준과 일치하는 SNO 클러스터에 Operator가 배포되고 스토리지를 프로비저닝하기 위해 필요한 리소스를 설정하도록 구성해야 합니다. Operator는 설치 후 사용되지 않은 모든 디스크를 사용합니다.
