AWS SDK를 사용하여 AWS STS에서 역할 수임

다음 코드 예제는 AWS STS에서 역할을 수임하는 방법을 보여줍니다.

작업 예시는 대규모 프로그램에서 발췌한 코드이며 컨텍스트에 맞춰 실행해야 합니다. 다음 코드 예제에서는 컨텍스트 내에서 이 작업을 확인할 수 있습니다.

다음 assume-role 명령은 IAM 역할 s3-access-example에 대한 일련의 단기 보안 인증 정보를 검색합니다.

aws sts assume-role \ --role-arn arn:aws:iam::123456789012:role/xaccounts3access \ --role-session-name s3-access-example

출력:

AWS CLI를 사용하는 경우 역할과 연결된 이름이 지정된 프로파일을 설정할 수 있습니다. 프로파일을 사용하면 AWS CLI에서 assume-role을 호출하고 대신 보안 인증 정보를 관리합니다. 자세한 내용은 AWS CLI 사용 설명서의 AWS CLI에서 IAM 역할 사용을 참조하세요.
