DeletePolicy 사용하기

DeletePolicy 사용하기 (SDK/CLI)

DeletePolicy(정책 삭제) API를 활용하는 방법을 코드 예시로 정리했어요. 각 예시는 어떤 동작을 하는지, 어떤 파라미터를 쓰는지 순서대로 살펴볼 수 있어요.

다음 코드 예시들은 DeletePolicy 를 어떻게 사용하는지 보여줘요.

.NET

    /// <summary>
    /// Delete an IAM policy.
    /// </summary>
    /// <param name="policyArn">The Amazon Resource Name (ARN) of the policy to
    /// delete.</param>
    /// <returns>A Boolean value indicating the success of the action.</returns>
    public async Task<bool> DeletePolicyAsync(string policyArn)
    {
        var response = await _IAMService.DeletePolicyAsync(new DeletePolicyRequest { PolicyArn = policyArn });
        return response.HttpStatusCode == System.Net.HttpStatusCode.OK;
    }

PowerShell Tools (V4)

예시 1: ARN이 arn:aws:iam::123456789012:policy/MySamplePolicy인 정책을 삭제해요. 정책을 삭제하기 전에 Remove-IAMPolicyVersion을 실행해 기본 버전을 제외한 모든 버전을 먼저 삭제해야 해요. 또한 IAM 사용자·그룹·역할에서 정책을 분리해야 해요.

Remove-IAMPolicy -PolicyArn arn:aws:iam::123456789012:policy/MySamplePolicy

예시 2: 먼저 기본이 아닌 모든 정책 버전을 삭제하고, 연결된 모든 IAM 엔터티에서 분리한 뒤, 마지막으로 정책 자체를 삭제해요. 첫 번째 줄은 정책 객체를 가져와요. 두 번째 줄은 기본 버전으로 표시되지 않은 모든 정책 버전을 컬렉션으로 가져온 뒤 각 정책을 삭제해요. 세 번째 줄은 정책이 연결된 모든 IAM 사용자·그룹·역할을 가져와요. 네 번째부터 여섯 번째 줄은 각 연결 엔터티에서 정책을 분리해요. 마지막 줄은 이 명령으로 관리형 정책과 남아 있는 기본 버전을 제거해요. 이 예시는 확인 프롬프트를 막기 위해 필요한 줄에 -Force 스위치 파라미터를 포함하고 있어요.
