실수로 인한 VM 삭제 방지

---

이 문서에서는 인스턴스 리소스의 deletionProtection 속성을 설정하여 특정 VM 인스턴스가 삭제되지 않도록 보호하는 방법을 설명합니다. VM 인스턴스에 대해 자세히 알아보려면 인스턴스 문서를 읽어보세요.

워크로드 중에는 SQL 서버를 실행하는 인스턴스, 라이선스 관리자로 사용되는 서버 등과 같이 애플리케이션 또는 서비스를 실행하는 데 필수적인 특정 VM 인스턴스가 존재할 수 있습니다. 이러한 VM 인스턴스는 지속적으로 실행되어야 하므로, VM이 삭제되지 않도록 보호할 수 있는 방법이 필요합니다.

deletionProtection 플래그를 설정하면 VM 인스턴스가 실수로 삭제되지 않도록 보호할 수 있습니다. 사용자가 deletionProtection 플래그를 설정한 VM 인스턴스를 삭제하려고 하면 요청이 실패합니다. compute.instances.create 권한이 부여된 사용자만 이 플래그를 재설정하여 리소스 삭제를 허용할 수 있습니다.

시작하기 전에

• 인스턴스 문서를 읽어보세요.
• 아직 인증을 설정하지 않았다면 설정합니다. 인증은 Google Cloud 서비스 및 API에 액세스하기 위해 ID를 확인하는 프로세스입니다. 로컬 개발 환경에서 코드 또는 샘플을 실행하려면 다음과 같이 Compute Engine에 인증하면 됩니다.

  Console

  When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

  gcloud

  1. Install the Google Cloud CLI, then initialize it by running the following command:

     gcloud init

     Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
  2. Set a default region and zone.

  Go

  이 페이지의 Go 샘플을 로컬 개발 환경에서 사용하려면 gcloud CLI를 설치 및 초기화한 다음 사용자 인증 정보로 애플리케이션 기본 사용자 인증 정보를 설정하세요.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

사양

• 삭제 방지를 해도 다음 작업은 방지되지 않습니다.

  • VM 내에서 인스턴스 종료(예: shutdown 명령어 실행)
  • 인스턴스 중지
  • 인스턴스 재설정
  • 인스턴스 정지
  • Google에서 감지된 사기 및 악용 사례로 인한 인스턴스 삭제
  • 프로젝트 종료로 인한 인스턴스 삭제

• 삭제 보호는 일반 VM과 선점형 VM 모두에 적용할 수 있습니다.

• 관리형 인스턴스 그룹에 속하는 VM에는 삭제 보호를 적용할 수 없지만, 비관리형 인스턴스 그룹에 속하는 인스턴스에 적용할 수 있습니다.

• 인스턴스 템플릿에는 삭제 방지를 지정할 수 없습니다.

권한

이 작업을 수행하려면 리소스에 대한 다음 권한 또는 다음 IAM 역할 중 하나를 부여받아야 합니다.

권한

• compute.instances.create

역할

• compute.admin
• compute.instanceAdmin.v1

인스턴스 생성 시 삭제 보호 설정

기본적으로 인스턴스의 삭제 보호는 사용 안함으로 설정됩니다. 아래 안내에 따라 삭제 보호를 사용 설정하세요.

콘솔

1. Google Cloud 콘솔에서 인스턴스 만들기 페이지로 이동합니다.

   인스턴스 만들기로 이동

2. 고급 옵션 섹션을 펼쳐서 다음을 수행합니다.

   1. 관리 섹션을 펼칩니다.
   2. 삭제 보호 사용 설정 체크박스를 선택합니다.

3. VM 만들기 프로세스를 계속 진행합니다.

gcloud

VM 인스턴스를 만들 때 --deletion-protection 또는 no-deletion-protection 플래그를 포함합니다. 삭제 보호는 기본적으로 사용 안함으로 설정되어 있으므로 사용 설정을 해야 합니다.

gcloud compute instances create [INSTANCE_NAME] --deletion-protection

여기에서 [INSTANCE_NAME]은 원하는 인스턴스 이름입니다.

인스턴스 생성 시 삭제 보호를 사용 안함으로 설정하려면 다음을 사용하세요.

gcloud compute instances create [INSTANCE_NAME] --no-deletion-protection

REST

API에서 VM 인스턴스를 만들 때, 요청 본문에 deletionProtection 속성을 포함합니다. 예를 들면 다음과 같습니다.

POST https://compute.googleapis.com/compute/v1/projects/[PROJECT_ID]/zones/[ZONE]/instances

{
  "name": "[INSTANCE_NAME]",
  "deletionProtection": "true",
  ...
}

삭제 보호를 사용하지 않도록 설정하려면 deletionProtection을 false로 설정합니다.

인스턴스에 삭제 보호가 설정되었는지 확인

gcloud tool 또는 API에서 인스턴스에 삭제 보호가 사용 설정되었는지 확인할 수 있습니다.

콘솔

1. VM 인스턴스 페이지로 이동합니다.

   VM 인스턴스로 이동

2. 메시지가 표시되면 프로젝트를 선택하고 계속을 클릭합니다.

3. VM 인스턴스 페이지에서 열 메뉴를 표시하고 삭제 보호를 사용 설정합니다.

   

4. 삭제 보호 아이콘이 표시된 새 열이 나타납니다. VM에 삭제 보호가 설정된 경우 인스턴스 이름 옆에 이 아이콘이 표시됩니다.

gcloud

gcloud CLI에서 instances describe 명령어를 실행하고 삭제 보호 필드를 검색합니다. 예를 들면 다음과 같습니다.

gcloud compute instances describe example-instance | grep "deletionProtection"

도구는 deletionProtection 속성 값을 반환합니다. true 또는 false로 설정하세요.

deletionProtection: false

기존 인스턴스의 삭제 보호 설정 변경

인스턴스의 현재 상태에 관계없이 기존 인스턴스의 삭제 보호를 전환할 수 있습니다. 특히 삭제 보호를 사용 혹은 사용 안함으로 설정하기 위해 인스턴스를 중지할 필요가 없습니다.

콘솔

1. VM 인스턴스 페이지로 이동합니다.

   VM 인스턴스로 이동

2. 메시지가 표시되면 프로젝트를 선택하고 계속을 클릭합니다.

3. 삭제 보호를 전환하려는 인스턴스의 이름을 클릭합니다. 인스턴스 세부정보 페이지가 표시됩니다.

4. 인스턴스 세부정보 페이지에서 다음 단계를 완료합니다.

   1. 페이지 상단에서 수정 버튼을 클릭합니다.

   2. 삭제 보호 아래에서 상자를 선택하여 삭제 보호를 사용 설정하거나 선택 해제하여 중지합니다.

      

   3. 변경사항을 저장합니다.

gcloud

gcloud CLI를 사용하여 --deletion-protection 또는 --no-deletion-protection 플래그를 사용하여 update 명령어를 실행합니다.

gcloud compute instances update [INSTANCE_NAME] \
    [--deletion-protection | --no-deletion-protection]

예를 들어 이름이 example-vm인 인스턴스에 대해 삭제 보호를 사용 설정하려면 다음을 실행합니다.

gcloud compute instances update example-vm --deletion-protection
