Mencegah penghapusan VM secara tidak sengaja

Dokumen ini menjelaskan cara melindungi instance VM tertentu dari penghapusan dengan menetapkan properti deletionProtection pada resource Instance. Untuk mempelajari instance VM lebih lanjut, baca dokumentasi Instance.

Sebagai bagian dari workload Anda, mungkin ada instance VM tertentu yang sangat penting untuk menjalankan aplikasi atau layanan Anda, seperti instance yang menjalankan server SQL, server yang digunakan sebagai pengelola lisensi, dan sebagainya. Instance VM ini mungkin perlu tetap berjalan tanpa batas waktu, sehingga Anda memerlukan cara untuk melindungi VM ini agar tidak dihapus.

Dengan menetapkan flag deletionProtection, instance VM dapat dilindungi dari penghapusan yang tidak disengaja. Jika pengguna mencoba menghapus instance VM yang telah Anda tetapkan flag deletionProtection-nya, permintaan akan gagal. Hanya pengguna yang telah diberi peran dengan izin compute.instances.create yang dapat mereset flag untuk mengizinkan resource dihapus.

Sebelum memulai

• Baca dokumentasi Instance.
• Siapkan autentikasi jika Anda belum melakukannya. Autentikasi memverifikasi identitas Anda untuk mengakses layanan Google Cloud dan API. Untuk menjalankan kode atau sampel dari lingkungan pengembangan lokal, Anda dapat melakukan autentikasi ke Compute Engine dengan memilih salah satu opsi berikut:

  Pilih tab untuk melihat bagaimana Anda berencana menggunakan contoh di halaman ini:

  Konsol

  Saat menggunakan konsol Google Cloud untuk mengakses layanan Google Cloud dan API, Anda tidak perlu menyiapkan autentikasi.

  gcloud

  1. Instal Google Cloud CLI. Setelah penginstalan, inisialisasi Google Cloud CLI dengan menjalankan perintah berikut:

     gcloud init

     Jika Anda menggunakan penyedia identitas (IdP) eksternal, Anda harus login ke gcloud CLI dengan identitas gabungan Anda terlebih dahulu.

     Catatan: Jika Anda telah menginstal gcloud CLI sebelumnya, pastikan Anda memiliki versi terbaru dengan menjalankan gcloud components update.
• Tetapkan region dan zona default.

Go

Untuk menggunakan contoh Go di halaman ini dalam lingkungan pengembangan lokal, instal dan lakukan inisialisasi gcloud CLI, lalu siapkan Kredensial Default Aplikasi dengan kredensial pengguna Anda.

1. Instal Google Cloud CLI.

2. Jika Anda menggunakan penyedia identitas (IdP) eksternal, Anda harus login ke gcloud CLI dengan identitas gabungan Anda terlebih dahulu.

3. Jika Anda menggunakan shell lokal, buat kredensial autentikasi lokal untuk akun pengguna Anda:

   gcloud auth application-default login

   Anda tidak perlu melakukan langkah ini jika menggunakan Cloud Shell.

   Jika error autentikasi ditampilkan, dan Anda menggunakan penyedia identitas (IdP) eksternal, konfirmasi bahwa Anda telah login ke gcloud CLI dengan identitas gabungan Anda.

Spesifikasi

• Pencegahan penghapusan tidak mencegah tindakan berikut:

  • Menghentikan instance dari dalam VM (seperti menjalankan perintah shutdown)
  • Menghentikan instance
  • Mereset instance
  • Menangguhkan instance
  • Instance dihapus karena penipuan dan penyalahgunaan setelah terdeteksi oleh Google
  • Instance dihapus karena penghentian project

• Perlindungan penghapusan dapat diterapkan pada VM reguler dan preemptible VM.

• Perlindungan penghapusan tidak dapat diterapkan pada VM yang merupakan bagian dari grup instance terkelola, tetapi dapat diterapkan pada instance yang merupakan bagian dari grup instance yang tidak terkelola.

• Pencegahan penghapusan tidak dapat ditentukan dalam template instance.

Izin

Untuk melakukan tugas ini, Anda harus telah diberi izin berikut ATAU salah satu dari peran IAM berikut di resource ini.

Izin

• compute.instances.create

Peran

• compute.admin
• compute.instanceAdmin.v1

Menetapkan perlindungan penghapusan selama pembuatan instance

Secara default, perlindungan penghapusan dinonaktifkan untuk instance Anda. Aktifkan perlindungan penghapusan menggunakan petunjuk di bawah.

Konsol

1. Di konsol Google Cloud , buka halaman Create an instance.

   Buka halaman Buat instance

2. Luaskan bagian Advanced options dan lakukan hal berikut:

   1. Luaskan bagian Management.
   2. Centang kotak Aktifkan perlindungan penghapusan.

3. Lanjutkan dengan proses pembuatan VM.

gcloud

Saat membuat instance VM, sertakan flag --deletion-protection atau no-deletion-protection. Perlindungan penghapusan dinonaktifkan secara default sehingga Anda dapat mengaktifkan perlindungan penghapusan:

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

dengan [INSTANCE_NAME] adalah nama instance yang diinginkan.

Untuk menonaktifkan perlindungan penghapusan selama pembuatan:

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

Di API, saat membuat instance VM, sertakan properti deletionProtection dalam isi permintaan Anda. Contoh:

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

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

Untuk menonaktifkan perlindungan penghapusan, tetapkan deletionProtection ke false.

Menentukan apakah instance mengaktifkan perlindungan penghapusan atau tidak

Anda dapat menentukan apakah instance memiliki perlindungan penghapusan yang diaktifkan di gcloud tool atau di API.

Konsol

1. Buka halaman VM instances.

   Buka instance VM

2. Jika diminta, pilih project Anda lalu klik Continue.

3. Di halaman VM instances, tarik ke bawah menu Columns dan aktifkan Deletion protection.

   

4. Kolom baru akan muncul dengan ikon perlindungan penghapusan. Jika VM mengaktifkan perlindungan penghapusan, ikon akan muncul di samping nama instance.

gcloud

Di gcloud CLI, jalankan perintah instances describe dan telusuri kolom perlindungan penghapusan. Contoh:

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

Alat ini menampilkan nilai properti deletionProtection, baik yang ditetapkan ke true maupun false:

deletionProtection: false

Mengaktifkan/menonaktifkan perlindungan penghapusan untuk instance yang ada

Anda dapat mengaktifkan/menonaktifkan perlindungan penghapusan untuk instance yang ada, terlepas dari status instance saat ini. Secara khusus, Anda tidak perlu menghentikan instance sebelum dapat mengaktifkan atau menonaktifkan perlindungan penghapusan.

Konsol

1. Buka halaman VM instances.

   Buka instance VM

2. Jika diminta, pilih project Anda lalu klik Continue.

3. Klik nama instance yang perlindungan penghapusannya ingin Anda aktifkan/nonaktifkan. Halaman detail instance akan ditampilkan.

4. Dari halaman detail instance, selesaikan langkah-langkah berikut:

   1. Klik tombol Edit di bagian atas halaman.

   2. Di bagian Deletion Protection, centang kotak untuk mengaktifkan atau hapus centang pada kotak untuk menonaktifkan perlindungan penghapusan.

      

   3. Simpan perubahan Anda.

gcloud

Dengan gcloud CLI, jalankan perintah update dengan flag --deletion-protection atau --no-deletion-protection:

gcloud compute instances update [INSTANCE_NAME] \

Misalnya, untuk mengaktifkan perlindungan penghapusan untuk instance bernama example-vm:

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