Membuat dan mengelola konfigurasi instance

Halaman ini menjelaskan cara menampilkan daftar, membuat, memperbarui, menghapus, dan menampilkan detail konfigurasi instance Spanner. Beberapa fungsionalitas konfigurasi instance kustom tidak tersedia di UI Google Cloud Console. Dalam kasus tersebut, gunakan perintah Google Cloud CLI (gcloud) yang disediakan.

Membuat daftar konfigurasi instance

Anda dapat menampilkan daftar semua konfigurasi instance Spanner yang tersedia dengan Google Cloud CLI dan library klien. Untuk menemukan daftar semua konfigurasi instance Spanner, lihat Konfigurasi regional dan multi-region.

gcloud

Jalankan perintah gcloud spanner instance-configs list:

gcloud spanner instance-configs list

C++

Untuk mempelajari cara menginstal dan menggunakan library klien untuk Spanner, lihat library klien Spanner.

void ListInstanceConfigs(
    google::cloud::spanner_admin::InstanceAdminClient client,
    std::string const& project_id) {
  int count = 0;
  auto project = google::cloud::Project(project_id);
  for (auto& config : client.ListInstanceConfigs(project.FullName())) {
    if (!config) throw std::move(config).status();
    ++count;
    std::cout << "Instance config [" << count << "]:\n"
              << config->DebugString();
  }
  if (count == 0) {
    std::cout << "No instance configs found in project " << project_id << "\n";
  }

Tampilkan detail konfigurasi instance

Anda dapat menampilkan detail konfigurasi instance apa pun dengan Google Cloud CLI dan library klien. Saat membuat konfigurasi instance kustom baru, Anda dapat menambahkan lokasi mana pun yang tercantum di optionalReplicas sebagai replika opsional. Jika tidak melihat lokasi replika hanya baca yang diinginkan, Anda dapat meminta region replika hanya baca opsional baru.

Untuk mengetahui informasi selengkapnya, lihat Membuat konfigurasi instance kustom.

gcloud

Jalankan perintah gcloud spanner instance-configs describe:

gcloud spanner instance-configs describe INSTANCE-CONFIG

Berikan nilai berikut:

INSTANCE-CONFIG
Konfigurasi instance, yang menentukan lokasi geografis instance dan memengaruhi cara data direplikasi. Misalnya, eur6 atau us-central1.

Untuk menampilkan detail konfigurasi dasar eur6, jalankan:

gcloud spanner instance-configs describe eur6

Berikut adalah contoh output untuk konfigurasi dasar eur6:

  configType: GOOGLE_MANAGED
  displayName: Europe (Netherlands, Frankfurt)
  freeInstanceAvailability: UNSUPPORTED
  leaderOptions:
  - europe-west3
  - europe-west4
  name: projects/cloud-spanner-demo/instanceConfigs/eur6
  optionalReplicas:

    location: us-east1
    type: READ_ONLY
  - displayName: South Carolina
    labels:
      cloud.googleapis.com/country: US
      cloud.googleapis.com/location: us-east1
      cloud.googleapis.com/region: us-east1
    location: us-east1
    type: READ_ONLY
  replicas:
  - defaultLeaderLocation: true
    location: europe-west4
    type: READ_WRITE
  - location: europe-west4
    type: READ_WRITE
  - location: europe-west3
    type: READ_WRITE
  - location: europe-west3
    type: READ_WRITE
  - location: europe-west6
    type: WITNESS

Catatan penggunaan tambahan:

  • baseConfig (hanya untuk konfigurasi kustom) mengarah ke konfigurasi instance dasar. Lihat konfigurasi regional yang tersedia dan konfigurasi multi-region yang tersedia untuk mengetahui daftar konfigurasi instance dasar yang dapat digunakan untuk membuat konfigurasi instance kustom.
  • configType menunjukkan apakah konfigurasi instance ini adalah konfigurasi instance dasar atau konfigurasi instance kustom.
  • etag (hanya untuk konfigurasi kustom) adalah representasi string berenkode base64 dari konfigurasi. Ini digunakan untuk kontrol konkurensi optimis.

Membuat konfigurasi instance kustom

Anda dapat membuat konfigurasi instance kustom dan menambahkan replika hanya baca opsional untuk menskalakan pembacaan dan mendukung pembacaan yang tidak berlaku lagi dengan latensi rendah. Lihat konfigurasi regional yang tersedia dan konfigurasi multi-region yang tersedia untuk mengetahui daftar konfigurasi instance dasar yang dapat digunakan untuk membuat konfigurasi instance kustom. Untuk mengetahui informasi selengkapnya tentang jenis replika dan replika Spanner, lihat Replikasi.

Untuk membuat konfigurasi instance kustom, Anda harus memiliki izin spanner.instanceConfigs.create. Secara default, peran yang memiliki izin spanner.instances.create juga akan memiliki izin spanner.instanceConfigs.create.

Konsol

Anda tidak dapat membuat konfigurasi instance kustom mandiri menggunakan Konsol Google Cloud. Untuk membuat instance dengan replika hanya baca, lihat petunjuk yang diberikan di bagian Membuat instance dengan konfigurasi instance kustom.

Anda dapat menggunakan Google Cloud CLI dan library klien untuk membuat konfigurasi instance kustom mandiri.

gcloud

Gunakan perintah gcloud spanner instance-configs create:

gcloud spanner instance-configs create CUSTOM-INSTANCE-CONFIG-ID  \
 --display-name=DISPLAY-NAME \
 --base-config=BASE-CONFIG \
 --labels=KEY=VALUE,[...] \
 --replicas=location=LOCATION, type=TYPE[:...]

Anda dapat menggunakan tanda --clone-config sebagai cara yang mudah untuk meng-clone konfigurasi dasar atau instance kustom lain sekaligus mendeklarasikan lokasi dan jenis replika kustom tertentu.

  gcloud spanner instance-configs create CUSTOM-INSTANCE-CONFIG-ID  \
  --display-name=DISPLAY-NAME \
  --clone-config=INSTANCE-CONFIG \
  --labels=KEY=VALUE,[...] \
  --add-replicas=location=LOCATION, type=TYPE[:...] \
  --skip-replicas=location=LOCATION, type=TYPE[:...]

Berikan nilai berikut:

CUSTOM-INSTANCE-CONFIG-ID
ID permanen yang unik dalam project Google Cloud Anda. Anda tidak dapat mengubah ID konfigurasi instance nanti. Awalan custom- diperlukan untuk menghindari konflik nama dengan konfigurasi instance dasar.
DISPLAY-NAME
Nama yang akan ditampilkan untuk konfigurasi instance kustom di Konsol Google Cloud.
Jika Anda memilih untuk menggunakan flag `--base-config` dan `--replicas`, berikan nilai berikut:
BASE-CONFIG
Nama region dari konfigurasi instance dasar tempat konfigurasi instance kustom Anda berada. Misalnya, eur6 atau regional-us-central1.
LOCATION
Nama region resource penayangan (replikas), misalnya, us-east1. Untuk mengetahui nama lokasi yang diterima, jalankan gcloud spanner instance-configs describe INSTANCE-CONFIG dan lihat daftar replicas dan optionalReplicas.
TYPE
Jenis replika. Untuk mengetahui lokasi terkait dan jenis replika yang diterima, jalankan gcloud spanner instance-configs describe INSTANCE-CONFIG dan lihat daftar replicas dan optionalReplicas. Jenisnya adalah salah satu dari berikut ini:
  • READ_ONLY
  • READ_WRITE
  • KEBUGARAN
Item dalam daftar dipisahkan dengan ":".
Kecuali jika tanda --[clone-config] digunakan, semua replika LOCATION dan TYPE harus ditentukan saat membuat konfigurasi instance kustom, termasuk yang telah ditentukan sebelumnya dalam konfigurasi dasar. Untuk mengetahui informasi selengkapnya, lihat gcloud instance-configs explain help-text.

Jika Anda memilih untuk menggunakan tanda --clone-config dan --add-replicas (hanya gunakan --skip-replicas jika ada replika yang ingin Anda lewati agar tidak di-clone), berikan nilai berikut:

  • --clone-config=INSTANCE-CONFIG

    Gunakan tanda ini sebagai cara yang mudah untuk meng-clone konfigurasi dasar atau instance kustom lainnya sekaligus mendeklarasikan lokasi dan jenis replika kustom tertentu. Kemudian, gunakan --add-replicas=location=LOCATION,type=TYPE untuk menentukan tempat Anda ingin menambahkan replika opsional.

    Misalnya, untuk membuat konfigurasi instance kustom dengan dua replika hanya baca di us-east1 sambil menyalin semua lokasi replika lainnya dari konfigurasi instance dasar eur6, jalankan:

    gcloud spanner instance-configs create custom-eur6 --clone-config=eur6 \
    --add-replicas=location=us-east1,type=READ_ONLY:location=us-east1,type=READ_ONLY
    
  • --skip-replicas=location=LOCATION,type=TYPE

    Gunakan tanda ini untuk melewati replika apa pun agar tidak di-clone.

    Misalnya, untuk membuat konfigurasi instance kustom dengan satu replika hanya baca di us-east4 sekaligus menyalin semua lokasi replika lainnya dari konfigurasi instance dasar nam3 kecuali replika hanya baca di us-central1, jalankan:

    gcloud spanner instance-configs create custom-nam3 --clone-config=nam3 \
      --add-replicas=location=us-east4,type=READ_ONLY \
      --skip-replicas=location=us-central1,type=READ_ONLY
    

Tanda dan nilai berikut bersifat opsional:

  • --labels=KEY=VALUE,[...]

    KEY dan VALUE: Daftar pasangan kunci dan nilai yang akan ditambahkan ke konfigurasi instance kustom Anda.

    Kunci harus diawali dengan karakter huruf kecil dan hanya berisi tanda hubung (-), garis bawah (_), huruf kecil, dan angka. Nilai hanya boleh berisi tanda hubung (-), garis bawah (_), huruf kecil, dan angka.

  • --validate-only

    Gunakan tanda ini untuk memvalidasi bahwa permintaan akan berhasil sebelum dieksekusi.

Misalnya, untuk membuat konfigurasi instance kustom dengan konfigurasi dasar eur6 dengan satu replika hanya baca tambahan di us-east1, jalankan:

gcloud spanner instance-configs create custom-eur6 \
  --display-name="Custom eur6" --clone-config=eur6 \
  --add-replicas=location=us-east1,type=READ_ONLY \

Anda juga dapat membuat konfigurasi instance kustom tanpa flag --clone-config:

gcloud spanner instance-configs create custom-eur6 \
  --display-name="Custom eur6" --base-config=eur6 \
  --replicas=location=europe-west4,type=READ_WRITE:location=europe-west3,type=READ_WRITE:location=europe-west4,type=READ_WRITE:location=europe-west3,type=READ_WRITE:location=europe-west6,type=WITNESS:location=us-east1,type=READ_ONLY

Anda akan melihat output berikut:

Creating instance-config...done.

Mengupdate konfigurasi instance kustom

Anda dapat mengubah nama tampilan dan label konfigurasi instance kustom. Anda tidak dapat mengubah atau mengupdate replika konfigurasi instance kustom.

gcloud

Gunakan perintah gcloud spanner instance-configs update:

gcloud spanner instance-configs update CUSTOM-INSTANCE-CONFIG-ID \
  --display-name=NEW-DISPLAY-NAME \
  --update-labels=KEY=VALUE,[...], \
  --etag=ETAG

Berikan nilai berikut:

CUSTOM-INSTANCE-CONFIG-ID
ID permanen konfigurasi instance kustom Anda. Ini akan dimulai dengan custom-.
NEW-DISPLAY-NAME
Nama baru yang akan ditampilkan untuk konfigurasi instance di Konsol Google Cloud.
KEY dan VALUE
Daftar key-value pair yang akan diperbarui.
Kunci harus dimulai dengan karakter huruf kecil dan hanya berisi tanda hubung (-), garis bawah (_), huruf kecil, dan angka. Nilai hanya boleh berisi tanda hubung (-), garis bawah (_), huruf kecil, dan angka.

Tanda dan nilai berikut bersifat opsional:

  • --etag=ETAG: Argumen ETAG dapat digunakan untuk memilih dan melewati update simultan dalam skenario baca-modifikasi-tulis.
  • --validate-only: Gunakan tanda ini untuk memvalidasi bahwa permintaan akan berhasil sebelum menjalankannya.

Contoh:

gcloud spanner instance-configs update custom-eur6 \
 --display-name="Customer managed europe replicas"
