8.2. 로그 전달 사용자 정의 리소스 업데이트

OpenShift Container Platform Log Forward API는 기술 프리뷰에서 OpenShift Container Platform 4.6에서 일반적으로 사용 가능으로 승격되었습니다. GA 릴리스에는 ClusterLogging 사용자 정의 리소스(CR)를 변경하고 LogForwarding 사용자 정의 리소스(CR)를 ClusterLogForwarder CR로 교체해야 하는 몇 가지 개선 사항 및 향상된 사항이 포함되어 있습니다.

프로세스

4.5의 ClusterLogForwarder CR을 4.6용 ClusterLogForwarding CR로 업데이트하려면 다음과 같이 수정합니다.

ClusterLogging 사용자 정의 리소스(CR)를 편집하여 logforwardingtechpreview 주석을 제거합니다.

샘플 ClusterLogging CR

1: logforwardingtechpreview 주석을 제거합니다.

ClusterLogForwarder CR을 내보내 ClusterLogForwarder 인스턴스의 YAML 파일을 생성합니다.

oc get LogForwarding instance -n openshift-logging -o yaml| tee ClusterLogForwarder.yaml

$ oc get LogForwarding instance -n openshift-logging -o yaml| tee ClusterLogForwarder.yaml
