VPC 환경에서 이용 가능합니다.
클러스터 생성시 부트스트랩 클러스터 관리자 허용을 선택하거나, [클러스터 상세] - [인증] 탭에서 AccessEntry를 추가하여 접근 가능한 보안주체를 등록합니다
클러스터를 생성한 액세스 항목을 클러스터 관리자로 추가
- 클러스터 생성 화면의 부트스트랩 클러스터 관리자 액세스 항목에서 클러스터 관리자 액세스 허용을 선택 합니다.
- 클러스터 생성을 요청한 사용자가 액세스 > AccessEntry에 IAM 액세스 항목 NRN에 등록됩니다.
참고
액세스 항목 방식의 클러스터는 SubAccount로 클러스터를 생성 할 때, 메인 계정이 클러스터 관리자로 자동 추가되지 않습니다.
액세스 항목을 클러스터에 추가
- 클러스터 상세화면 > 액세스 탭 > AccessEntry > [생성하기] 버튼을 클릭합니다.
- 추가할 액세스 항목의 정보를 입력합니다.
- IAM 보안 주체 : 정책을 적용할 액세스 항목의 NRN
- 그룹(선택사항) : 클러스터에서 인증되는 사용자 그룹. (최대 30개)
- 정책 : 보안주체에 적용될 클러스터 접근 정책의 목록.
- Scope: 정책의 적용 범위 (Cluster / Namespace)
- Namespaces(선택사항): Scope이 Namespace인 경우 정책이 적용될 Namespace 목록. '*-ns'로 패턴 지정 가능. (최대 50개)
- Policy: 적용될 정책
- NKSClusterAdminPolicy: 클러스터의 모든 권한 보유
- NKSAdminPolicy : 리소스의 대부분 권한 보유
- NKSEditPolicy: 쓰기 권한 보유
- NKSViewPolicy: 읽기 권한 보유
- [생성] 버튼을 눌러 정책을 등록합니다.
- 등록된 보안 주체의 AccessKey로 권한이 부여되었는지 확인합니다.
액세스 정책
Ncloud Kubernetes Service 클러스터의 IAM 인증 액세스 항목에 적용 가능한 정책은 NKSClusterAdminPolicy, NKSAdminPolicy, NKSEditPolicy, NKSViewPolicy이 있습니다.
주의
- Managed NKS의 경우 아래 권한에서 노드, 시스템 Namespace등의 리소스 사용 및 사용자가장 등이 제한됩니다.
- 액세스 정책을 통해 적용된 권한은 kubectl auth can-i --list 명령으로 확인이 불가능합니다.
- 사용자/그룹 가장하여 kubectl 명령을 사용하는 경우 액세스 항목에 적용된 액세스 정책이 적용되지 않습니다.
