Mendapatkan daftar VM

Linux Windows

Untuk melihat ringkasan VM yang berjalan di project Anda, dapatkan daftar VM. Dokumen ini menunjukkan cara mendapatkan daftar VM di semua zona atau di zona tertentu.

Sebelum memulai

Jika Anda belum melakukannya, siapkan autentikasi. Autentikasi adalah proses verifikasi identitas Anda untuk mengakses layanan dan API Google Cloud. Untuk menjalankan kode atau contoh dari lingkungan pengembangan lokal, Anda dapat mengautentikasi ke Compute Engine dengan memilih salah satu opsi berikut:

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.

Mendapatkan daftar VM

Konsol

Di Konsol Google Cloud, buka halaman Instance VM:

Buka instance VM

gcloud

Dapatkan daftar gabungan semua VM di semua zona untuk project menggunakan perintah gcloud compute instances list:

gcloud compute instances list

Untuk mempersempit daftar VM ke zona tertentu, gunakan perintah sebelumnya dengan flag --zones.

Go

Contoh berikut ini memberikan daftar instance di semua zona dalam project Anda:

Sebelum mencoba contoh ini, ikuti petunjuk penyiapan Go yang berada di dalam Panduan memulai Compute Engine menggunakan library klien. Untuk informasi selengkapnya, lihat dokumentasi referensi API Go Compute Engine.

Untuk melakukan autentikasi ke Compute Engine, siapkan Kredensial Default Aplikasi. Untuk mengetahui informasi selengkapnya, baca Menyiapkan autentikasi untuk lingkungan pengembangan lokal.

REST

Dapatkan daftar gabungan semua VM di semua zona dalam project menggunakan metode instances.aggregatedList:

GET https://compute.googleapis.com/compute/v1/projects/PROJECT/aggregated/instances

Ganti PROJECT dengan nama project tempat daftar VM diperoleh.

Untuk mempersempit daftar VM ke zona tertentu, gunakan metode instances.list:

GET https://compute.googleapis.com/compute/v1/projects/PROJECT/zones/ZONE/instances

Ganti kode berikut:

PROJECT: nama project tempat daftar VM diambil
ZONE: zona tempat daftar VM diambil
