12.7. 보안 컨텍스트 제약 조건 명령 참조
OpenShift CLI(oc)를 사용하여 인스턴스의 SCC(보안 컨텍스트 제약 조건)를 일반 API 오브젝트로 관리할 수 있습니다.
12.7.1. 보안 컨텍스트 제약 조건 나열
현재 SCC 목록을 가져오려면 다음을 실행합니다.
$ oc get scc

12.7.2. 보안 컨텍스트 제약 조건 검사
SCC가 적용되는 사용자, 서비스 계정 및 그룹을 포함하여 특정 SCC에 대한 정보를 볼 수 있습니다.
예를 들어 restricted SCC를 검사하려면 다음을 실행합니다.
$ oc describe scc restricted
출력 예
