Mendapatkan, Mencantumkan, dan Menghapus Template Instance

Halaman ini menjelaskan cara mendapatkan, mencantumkan, dan menghapus template instance.

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 informasi tentang template instance

Konsol

Di konsol Google Cloud, buka halaman Instance Templates.
Buka halaman Instance templates
Klik nama template instance untuk melihat detail template tersebut.

gcloud

Untuk mendapatkan informasi tentang template instance regional atau global, gunakan instance-templates describe command.

Untuk template instance regional, gunakan perintah berikut:

gcloud compute instance-templates describe INSTANCE_TEMPLATE_NAME \
    --region=REGION

Untuk template instance global, gunakan perintah berikut:

gcloud compute instance-templates describe INSTANCE_TEMPLATE_NAME

Go

import (

// getInstanceTemplate retrieves an instance template, which you can use to create virtual machine
// (VM) instances and managed instance groups (MIGs).
func getInstanceTemplate(projectID, templateName string) (*computepb.InstanceTemplate, error) {
	// projectID := "your_project_id"
	// templateName := "your_template_name"

	ctx := context.Background()
	instanceTemplatesClient, err := compute.NewInstanceTemplatesRESTClient(ctx)
	if err != nil {
		return nil, fmt.Errorf("NewInstanceTemplatesRESTClient: %w", err)
	}
	defer instanceTemplatesClient.Close()

	req := &computepb.GetInstanceTemplateRequest{
		Project:          projectID,
		InstanceTemplate: templateName,
	}

	return instanceTemplatesClient.Get(ctx, req)

REST

Untuk mendapatkan informasi tentang template instance regional, gunakan metode regionInstanceTemplates.get seperti berikut:

GET https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/regions/REGION/instanceTemplates/INSTANCE_TEMPLATE_NAME

Untuk mendapatkan informasi tentang template instance global, gunakan instanceTemplates.get sebagai berikut:

GET https://compute.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/instanceTemplates/[INSTANCE_TEMPLATE]

Membuat daftar template instance

Untuk mendapatkan daftar template instance yang Anda buat:

Konsol

Halaman Template Instance mencantumkan semua template instance dalam project Anda.

Buka halaman Instance Templates

gcloud

Untuk mendapatkan daftar semua template instance regional, gunakan perintah berikut:

gcloud compute instance-templates list \
    --regions

Untuk mendapatkan daftar template instance regional di region tertentu, gunakan perintah berikut:

gcloud compute instance-templates list \
    --filter="region:(REGION)"

Untuk mendapatkan daftar template instance global, gunakan perintah berikut:

gcloud compute instance-templates list \
    --global

Untuk mendapatkan daftar semua template instance, termasuk template regional dan global, gunakan perintah berikut:

Menghapus template instance

Menghapus template instance akan menyingkirkannya dari daftar template. Anda tidak dapat menghapus template instance jika grup instance terkelola mereferensikannya.

Konsol

Di konsol Google Cloud, buka halaman Instance Templates.
Buka halaman Instance Templates
Pilih instance tempate yang ingin dihapus.
Klik Delete.

gcloud

Dengan menggunakan Google Cloud CLI, jalankan:

gcloud compute instance-templates delete INSTANCE_TEMPLATE_NAME

Untuk template instance regional, INSTANCE_TEMPLATE_NAME harus berisi URL template yang lengkap. Contoh, https://www.googleapis.com/compute/v1/projects/example-project/regions/us-central1/instanceTemplates/example-regional-instance-template.

REST

Untuk menghapus template instance regional, buat permintaan regionInstanceTemplates.delete:

DELETE https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/regions/REGION/instanceTemplates/INSTANCE_TEMPLATE_NAME

Untuk menghapus template instance global, buat permintaan instanceTemplates.delete:

DELETE https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/global/instanceTemplates/INSTANCE_TEMPLATE_NAME

Terkadang VM dalam grup instance terkelola tidak sinkron dengan grup lainnya, dan menggunakan template instance lain dari grup lainnya. Jika VM dalam grup instance terkelola menggunakan template lain dari yang ditentukan pada grup, VM tersebut akan terus menggunakan templatenya untuk perbaikan meskipun template tersebut dihapus. Untuk informasi selengkapnya tentang cara menerapkan template instance baru, baca Menerapkan konfigurasi baru ke VM di MIG.
