Menghentikan atau memulai ulang instance Compute Engine

Dokumen ini menjelaskan cara menghentikan atau memulai ulang instance Compute Engine. Untuk mempelajari lebih lanjut efek penghentian instance, serta perbedaan antara menangguhkan, menghentikan, atau mereset instance, lihat Menangguhkan, menghentikan, atau mereset instance Compute Engine.

Menghentikan instance berguna jika Anda tidak lagi menggunakannya, atau untuk mengubah propertinya—misalnya, untuk mengubah jenis mesinnya, atau menghapus disk yang terpasang dan di-mount. Setelah menghentikan instance, Anda dapat melakukan hal berikut:

  • Mulai ulang untuk melanjutkan beban kerja Anda.

  • Hapus jika Anda tidak lagi memerlukannya.

Untuk mengotomatiskan penghentian atau mulai ulang instance, lihat hal berikut:

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:

Peran yang diperlukan

Untuk mendapatkan izin yang diperlukan untuk menghentikan dan memulai ulang instance komputasi, minta administrator untuk memberi Anda peran IAM Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1) di project. Untuk mengetahui informasi selengkapnya tentang cara memberikan peran, lihat Mengelola akses ke project, folder, dan organisasi.

Peran bawaan ini berisi izin yang diperlukan untuk menghentikan dan memulai ulang instance komputasi. Untuk melihat izin yang benar-benar diperlukan, luaskan bagian Izin yang diperlukan:

Izin yang diperlukan

Izin berikut diperlukan untuk menghentikan dan memulai ulang instance komputasi:

  • Untuk menghentikan instance: compute.instances.stop pada instance
  • Untuk menghentikan instance dari dalam OS tamu: compute.instances.setMetadata pada instance jika menggunakan kunci SSH publik level instance.
  • Untuk memulai ulang instance: compute.instances.start pada instance
  • Untuk memulai ulang instance yang menggunakan kunci enkripsi: compute.instances.startWithEncryptionKey di instance

Anda mungkin juga bisa mendapatkan izin ini dengan peran khusus atau peran bawaan lainnya.

Menghentikan instance

Saat Anda menghentikan instance komputasi dan Compute Engine mengubah statusnya menjadi TERMINATED, instance akan mempertahankan resource yang terpasang, setelan konfigurasi, alamat IP internal, alamat MAC, dan metadata. Namun, instance kehilangan data dalam memori dan status aplikasinya. Jika Anda perlu mempertahankannya, tangguhkan instance.

Anda dapat menghentikan instance menggunakan metode berikut. Metode yang Anda pilih bergantung pada apakah instance memiliki disk SSD Lokal yang terpasang, dan cara Anda ingin menangani skrip shutdown:

  • Menghentikan instance tanpa disk SSD Lokal

    Anda dapat menghentikan satu atau beberapa instance secara bersamaan yang tidak memiliki disk SSD Lokal.

  • Menghentikan instance dengan disk SSD Lokal

    Saat menghentikan satu atau beberapa instance yang memiliki disk SSD Lokal yang terpasang, Anda dapat memilih untuk menghapus atau mempertahankan (Pratinjau) data di disk tersebut.

  • Menghentikan instance dari OS tamu

    Anda dapat menghentikan instance dari dalam OS tamunya. Hal ini berguna jika Anda terhubung ke instance atau memiliki skrip shutdown yang perlu dijalankan sebelum instance berhenti. Namun, kecuali jika Anda mencadangkan data dari disk SSD Lokal ke volume penyimpanan persisten secara manual, menghentikan instance dari dalam OS tamu akan menghapus semua data di disk SSD Lokal yang terpasang.

Setelah menghentikan instance, Anda dapat memulai ulang instance jika diperlukan, atau menghapus instance jika Anda tidak lagi membutuhkannya.

Menghentikan instance tanpa disk SSD Lokal

Anda dapat menghentikan beberapa instance komputasi secara bersamaan atau instance individual. Untuk beberapa instance, gunakan konsol Google Cloud atau, untuk instance yang berada di zona yang sama, Google Cloud CLI. Untuk setiap instance, pilih salah satu opsi berikut:

Konsol

  1. Di konsol Google Cloud, buka halaman Instance VM.

    Buka instance VM

  2. Pilih instance yang sedang berjalan untuk dihentikan.

  3. Klik Berhenti, lalu klik Berhenti untuk mengonfirmasi.

gcloud

Untuk menghentikan satu atau beberapa instance dalam satu zona, gunakan perintah gcloud compute instances stop:

gcloud compute instances stop INSTANCE_NAMES \
    --zone=ZONE

Ganti kode berikut:

  • INSTANCE_NAMES: daftar nama instance yang dipisahkan spasi—misalnya, instance-01 instance-02 instance-03.

  • ZONE: zona tempat instance berada.

Go 

import (
	"context"
	"fmt"
	"io"

	compute "cloud.google.com/go/compute/apiv1"
	computepb "cloud.google.com/go/compute/apiv1/computepb"

// stopInstance stops a started Google Compute Engine instance
func stopInstance(w io.Writer, projectID, zone, instanceName string) error {
	// projectID := "your_project_id"
	// zone := "europe-central2-b"
	// instanceName := "your_instance_name"

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

	req := &computepb.StopInstanceRequest{
		Project:  projectID,
		Zone:     zone,
		Instance: instanceName,
	}

	op, err := instancesClient.Stop(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to stop instance: %w", err)
	}

	if err = op.Wait(ctx); err != nil {
		return fmt.Errorf("unable to wait for the operation: %w", err)
	}

	fmt.Fprintf(w, "Instance stopped\n")

	return nil

Ganti kode berikut:

  • INSTANCE_NAME: nama instance.

  • PROJECT_ID: ID project tempat instance berada.

  • ZONE: zona tempat instance berada.

Menghentikan instance dengan disk SSD Lokal

Berdasarkan jumlah instance komputasi yang ingin Anda hentikan secara bersamaan dan apakah Anda perlu mempertahankan data disk SSD Lokal yang terpasang, lakukan hal berikut:

  • Untuk mempertahankan data disk SSD Lokal yang terpasang ke instance, hentikan instance menggunakan gcloud CLI atau REST API.

  • Untuk menghentikan beberapa instance secara bersamaan, gunakan konsol Google Cloud atau, untuk instance yang berada di zona yang sama, gcloud CLI.

Untuk menghentikan satu atau beberapa instance yang memiliki disk SSD Lokal terpasang, pilih salah satu opsi berikut:

Konsol

  1. Di konsol Google Cloud, buka halaman Instance VM.

    Buka instance VM

  2. Pilih instance yang sedang berjalan untuk dihentikan.

  3. Klik Berhenti, lalu klik Berhenti untuk mengonfirmasi.

gcloud

Saat menghentikan satu atau beberapa instance dalam satu zona yang memiliki disk SSD Lokal yang terpasang, tentukan apakah akan menghapus atau mempertahankan data SSD Lokal sebagai berikut:

  • Untuk menghapus data SSD Lokal, gunakan perintah gcloud compute instances stop dengan flag --discard-local-ssd=true:

    gcloud compute instances stop INSTANCE_NAMES \
    --discard-local-ssd=true \
    --zone=ZONE

  • Untuk mempertahankan data SSD Lokal, gunakan perintah gcloud beta compute instances stop dengan flag --discard-local-ssd=false:

    gcloud beta compute instances stop INSTANCE_NAMES \
    --discard-local-ssd=false \
    --zone=ZONE

Ganti kode berikut:

  • INSTANCE_NAMES: daftar nama instance yang dipisahkan spasi—misalnya, instance-01 instance-02 instance-03.

  • ZONE: zona tempat instance berada.

REST

Saat menghentikan instance yang memiliki disk SSD Lokal yang terpasang, tentukan apakah data SSD Lokal akan dihapus atau dipertahankan sebagai berikut:

  • Untuk menghapus data SSD Lokal, buat permintaan POST ke metode instances.stop. Di URL permintaan, sertakan parameter kueri discardLocalSsd yang ditetapkan ke true:

    POST https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/INSTANCE_NAME/stop?discardLocalSsd=true

  • Untuk mempertahankan data SSD Lokal, buat permintaan POST ke metode beta.instances.stop. Di URL permintaan, sertakan parameter kueri discardLocalSsd yang ditetapkan ke false:

    POST https://compute.googleapis.com/compute/beta/projects/PROJECT_ID/zones/ZONE/instances/INSTANCE_NAME/stop?discardLocalSsd=false

Ganti kode berikut:

  • PROJECT_ID: ID project tempat instance berada.

  • ZONE: zona tempat instance berada.

  • INSTANCE_NAME: nama instance.

Menghentikan instance dari OS tamu

Jika Anda menghentikan instance komputasi yang memiliki disk SSD Lokal yang terpasang, menghentikan instance dari dalam OS tamu akan menghapus data SSD Lokal. Jika ingin mempertahankan data SSD Lokal, sebelum menghentikan instance, Anda harus menyalin data secara manual ke opsi penyimpanan persisten, seperti volume Hyperdisk atau Persistent Disk Google Cloud yang terpasang, atau bahkan Cloud Storage.

Untuk menghentikan instance dari dalam OS tamu, pilih salah satu opsi berikut:

Linux

  1. Jika Anda belum melakukannya, hubungkan ke instance.

  2. Untuk menghentikan instance, pilih salah satu metode berikut:

    • Untuk penonaktifan bersih yang memungkinkan instance menjalankan skrip penonaktifan sebelum mematikan OS tamu, jalankan perintah berikut:

      sudo shutdown -h now

    • Jika tidak, untuk memaksa penonaktifan, jalankan perintah berikut:

      sudo poweroff

Windows

  1. Jika Anda belum melakukannya, hubungkan ke instance menggunakan salah satu metode berikut:

  2. Untuk menghentikan instance, pilih salah satu metode berikut:

    • Untuk penonaktifan bersih yang memungkinkan instance menjalankan skrip penonaktifan sebelum mematikan OS tamu, jalankan perintah berikut:

      shutdown /s

    • Jika tidak, untuk memaksa penonaktifan, jalankan perintah berikut:

      shutdown /f

Memulai ulang instance

Anda dapat memulai ulang instance komputasi yang telah dihentikan sepenuhnya, yaitu saat status instance adalah TERMINATED.

Jika Anda memilih untuk mempertahankan data disk SSD Lokal saat menghentikan instance, Anda mungkin perlu memasang ulang disk SSD Lokal setelah memulai ulang instance. Untuk mengetahui informasi selengkapnya tentang cara memasang disk SSD Lokal, lihat Memformat dan memasang perangkat SSD Lokal.

Untuk memulai ulang instance, gunakan salah satu metode berikut berdasarkan apakah instance memiliki disk terenkripsi yang terpasang:

Memulai ulang instance tanpa disk terenkripsi

Anda dapat memulai ulang beberapa instance komputasi secara bersamaan atau instance individual. Untuk beberapa instance, gunakan konsol Google Cloud atau, untuk instance yang berada di zona yang sama, gcloud CLI. Untuk setiap instance, pilih salah satu opsi berikut:

Konsol

  1. Di konsol Google Cloud, buka halaman Instance VM.

    Buka instance VM

  2. Pilih satu atau beberapa instance.

  3. Klik Start / Resume.

gcloud

Untuk memulai ulang satu atau beberapa instance dalam satu zona, gunakan perintah gcloud compute instances start:

gcloud compute instances start INSTANCE_NAMES \
    --zone=ZONE

Ganti kode berikut:

  • INSTANCE_NAMES: daftar nama instance yang dipisahkan spasi—misalnya, instance-01 instance-02 instance-03.

  • ZONE: zona tempat instance berada.

REST

Untuk memulai ulang instance, buat permintaan POST ke metode instances.start:

 POST https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/INSTANCE_NAME/start

Ganti kode berikut:

  • INSTANCE_NAME: nama instance yang akan dimulai ulang.

  • PROJECT_ID: ID project tempat instance berada.

  • ZONE: zona tempat instance berada.

Memulai ulang instance dengan disk terenkripsi

Saat memulai ulang instance komputasi yang dihentikan yang memiliki disk terpasang yang dienkripsi menggunakan kunci enkripsi yang disediakan pelanggan, Anda harus memberikan informasi kunci enkripsi.

Untuk memulai ulang beberapa instance secara bersamaan, gunakan konsol Google Cloud atau, untuk instance yang berada di zona yang sama, gcloud CLI. Jika tidak, untuk memulai ulang satu instance, pilih salah satu opsi berikut:

Konsol

  1. Di konsol Google Cloud, buka halaman Instance VM.

    Buka instance VM

  2. Pilih instance yang akan dimulai ulang.

  3. Klik Start / Resume.

  4. Tentukan kunci enkripsi untuk setiap disk terenkripsi yang terpasang ke instance, lalu klik Mulai.

gcloud

Untuk memulai ulang satu atau beberapa instance dalam satu zona yang menggunakan disk terenkripsi, gunakan perintah gcloud compute instances start dengan flag --csek-key-file. Jika Anda menggunakan kunci yang digabungkan RSA, gunakan perintah gcloud beta compute instances start dengan flag --csek-key-file:

gcloud compute instances start INSTANCE_NAMES \
    --csek-key-file=ENCRYPTION_KEY_FILE \
    --zone=ZONE

Ganti kode berikut:

  • INSTANCE_NAMES: daftar nama instance yang dipisahkan spasi—misalnya, instance-01 instance-02 instance-03.

  • ENCRYPTION_KEY_FILE: jalur relatif ke file JSON yang berisi kunci enkripsi yang disediakan pelanggan. Anda hanya dapat memulai ulang beberapa instance secara bersamaan jika instance menggunakan kunci enkripsi yang sama yang disediakan pelanggan.

  • ZONE: zona tempat instance berada.
