사용법:
|
||||
bash scripts/validate/k3s-secret-encryption-restore-evidence.sh \
|
||||
--emit-result --bundle-metadata FILE --output FILE
|
||||
bash scripts/validate/k3s-secret-encryption-restore-evidence.sh \
|
||||
--record --bundle-metadata FILE --result-file FILE
|
||||
bash scripts/validate/k3s-secret-encryption-restore-evidence.sh --check
|
||||
|
||||
--emit-result는 격리 복구 host의 live 상태를 검사한 뒤 결과 파일을 만듭니다.
|
||||
--record는 복구 환경과 bundle 복사본 파기 확인 뒤 운영 host에 증거를 등록합니다.
|
||||
--check는 권위 post bundle, live 암호화 상태와 등록된 증거를 읽기 전용 검사합니다.
