VM 목록 가져오기

Linux Windows

프로젝트에서 실행 중인 VM 요약을 보려면 VM 목록을 가져옵니다. 이 문서에서는 모든 영역 또는 특정 영역에서 VM 목록을 가져오는 방법을 보여줍니다.

시작하기 전에

아직 인증을 설정하지 않았다면 설정합니다. 인증은 Google Cloud 서비스 및 API에 액세스하기 위해 ID를 확인하는 프로세스입니다. 로컬 개발 환경에서 코드 또는 샘플을 실행하려면 다음 옵션 중 하나를 선택하여 Compute Engine에 인증하면 됩니다.

Select the tab for how you plan to use the samples on this page:
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.

VM 목록 가져오기

콘솔

Google Cloud 콘솔에서 VM 인스턴스 페이지로 이동합니다.

VM 인스턴스로 이동

gcloud

gcloud compute instances list 명령어를 사용하여 프로젝트에 대해 모든 영역에 있는 모든 VM 집계 목록을 가져옵니다.

gcloud compute instances list

VM 목록 범위를 특정 영역으로 제한하려면 이전 명령어에 --zones 플래그를 사용합니다.

Go

다음 예에서는 프로젝트의 모든 영역에서 인스턴스 목록을 가져옵니다.

이 샘플을 사용해 보기 전에 Compute Engine 빠른 시작: 클라이언트 라이브러리 사용의 Go 설정 안내를 따르세요. 자세한 내용은 Compute Engine Go API 참고 문서를 확인하세요.

Compute Engine에 인증하려면 애플리케이션 기본 사용자 인증 정보를 설정합니다. 자세한 내용은 로컬 개발 환경의 인증 설정을 참조하세요.
