시작하기 전에

Google Cloud 프로젝트 만들기

이 빠른 시작을 진행하려면 새 Google Cloud 프로젝트가 필요합니다.

경고: 기존 프로젝트를 사용하는 경우 이 빠른 시작을 완료하면 일부 사용자가 해당 프로젝트의 리소스에 액세스할 수 있습니다.

1. Google Cloud 계정에 로그인합니다. Google Cloud를 처음 사용하는 경우 계정을 만들고 Google 제품의 실제 성능을 평가해 보세요. 신규 고객에게는 워크로드를 실행, 테스트, 배포하는 데 사용할 수 있는 $300의 무료 크레딧이 제공됩니다.
2. Google Cloud CLI를 설치합니다.

3. gcloud CLI를 초기화하려면 다음 명령어를 실행합니다.

   gcloud init

4. Create or select a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   • Create a Google Cloud project:

     gcloud projects create PROJECT_ID

     Replace PROJECT_ID with a name for the Google Cloud project you are creating.

   • Select the Google Cloud project that you created:

     gcloud config set project PROJECT_ID

     Replace PROJECT_ID with your Google Cloud project name.

5. Resource Manager API를 사용 설정합니다.

   gcloud services enable cloudresourcemanager.googleapis.com

6. Google 계정의 로컬 인증 사용자 인증 정보를 만듭니다.

   gcloud auth application-default login

7. Google 계정에 역할을 부여합니다. 다음 각 IAM 역할에 대해 다음 명령어를 한 번씩 실행합니다. roles/resourcemanager.projectIamAdmin

   gcloud projects add-iam-policy-binding PROJECT_ID --member="user:EMAIL_ADDRESS" --role=ROLE

   • PROJECT_ID를 프로젝트 ID로 바꿉니다.
   • EMAIL_ADDRESS를 이메일 주소로 바꿉니다.
   • ROLE을 각 개별 역할로 바꿉니다.
8. Google Cloud CLI를 설치합니다.

9. gcloud CLI를 초기화하려면 다음 명령어를 실행합니다.

   gcloud init

10. Create or select a Google Cloud project.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

11. Resource Manager API를 사용 설정합니다.

    gcloud services enable cloudresourcemanager.googleapis.com

12. Google 계정의 로컬 인증 사용자 인증 정보를 만듭니다.

    gcloud auth application-default login

13. Google 계정에 역할을 부여합니다. 다음 각 IAM 역할에 대해 다음 명령어를 한 번씩 실행합니다. roles/resourcemanager.projectIamAdmin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:EMAIL_ADDRESS" --role=ROLE

    • PROJECT_ID를 프로젝트 ID로 바꿉니다.
    • EMAIL_ADDRESS를 이메일 주소로 바꿉니다.
    • ROLE을 각 개별 역할로 바꿉니다.

허용 정책 읽기, 수정, 쓰기

이 빠른 시작의 코드 스니펫은 다음 작업을 수행합니다.

• Google Cloud 프로젝트를 관리하는 Resource Manager 서비스를 초기화합니다.
• 프로젝트의 허용 정책을 읽습니다.
• Google 계정에 로그 작성자 역할(roles/logging.logWriter)을 부여하여 허용 정책을 수정합니다.
• 업데이트된 허용 정책을 작성합니다.
• 프로젝트 수준에서 로그 작성자 역할(roles/logging.logWriter)이 있는 모든 주 구성원을 출력합니다.
• 로그 작성자 역할을 취소합니다.

코드 스니펫을 실행하기 전에 다음 값을 바꿉니다.

• your-project: 프로젝트의 ID입니다.
• your-member: Google 계정의 이메일 주소(프리픽스 user:)입니다. 예를 들면 user:[e-mail]입니다.

참고: 다음 스니펫은 프로젝트의 허용 정책을 가져오고, 수정하고, 설정하여 액세스 권한을 수정합니다. 허용 정책에 대한 자세한 내용은 IAM 개요를 참조하세요.

수고하셨습니다 Resource Manager API의 IAM 메서드를 사용하여 프로젝트의 액세스 권한을 수정했습니다.

어땠나요?

완료

축하합니다. 빠른 시작에서 마음에 들었던 점은 무엇인가요? 어떤 점을 개선해야 한다고 생각하시나요? Google에 알려주세요..

문제 발생

불편을 끼쳐드려 죄송합니다. 어떤 문제가 발생했는지 알려주세요. 빠른 시작을 수정하겠습니다.

삭제

1. 선택사항: 만든 사용자 인증 정보를 취소하고 로컬 사용자 인증 정보 파일을 삭제합니다.

   gcloud auth application-default revoke

2. 선택사항: gcloud CLI에서 사용자 인증 정보를 취소합니다.

   gcloud auth revoke

다음 단계

• IAM의 작동 원리 읽어보기
• 액세스 권한 부여, 변경, 취소 자세히 알아보기
• Policy Troubleshooter를 사용하여 액세스 문제 해결하기
