Sebelum memulai

  1. Aktifkan Secret Manager API, satu kali per project.
  2. Tetapkan peran Admin Secret Manager (roles/secretmanager.admin) di project, folder, atau organisasi.

  3. Lakukan autentikasi ke Secret Manager API menggunakan salah satu cara berikut:

    • Jika Anda menggunakan library klien untuk mengakses Secret Manager API, siapkan Kredensial Default Aplikasi.
    • Jika Anda menggunakan Google Cloud CLI untuk mengakses Secret Manager API, gunakan kredensial Google Cloud CLI untuk melakukan autentikasi.
    • Untuk mengautentikasi panggilan REST, gunakan kredensial Google Cloud CLI atau Kredensial Default Aplikasi.

Membuat secret dan mengakses versi secret

Contoh berikut menunjukkan cara membuat secret dan mengakses konten versi secret.

Konsol

Untuk membuat secret dan versi secret:

  1. Buka halaman Secret Manager di konsol Google Cloud.

    Buka halaman Secret Manager

  2. Di halaman Secret Manager, klik Buat Secret.

  3. Di halaman Create secret, di bagian Name, masukkan my-secret.

  4. Di kolom Secret value, masukkan my super secret data.

  5. Klik tombol Buat secret.

Untuk mengakses konten versi secret:

  1. Buka halaman Secret Manager di konsol Google Cloud.

    Buka halaman Secret Manager

  2. Di halaman Secret Manager, klik my-secret.

  3. Di halaman Detail secret, di tabel Versions, temukan versi 1.

  4. Di kolom Tindakan, klik Lihat lainnya.

  5. Klik Lihat nilai rahasia dari menu.

  6. Dialog akan muncul yang menampilkan nilai secret. Klik Done untuk menutup dialog.

gcloud

Untuk menggunakan Secret Manager di command line, pertama-tama Instal atau upgrade ke Google Cloud CLI versi 378.0.0 atau yang lebih tinggi. Di Compute Engine atau GKE, Anda harus melakukan autentikasi dengan cakupan cloud-platform.

Untuk membuat secret dan menyimpan string sebagai konten versi secret pertama:

$ echo -n "my super secret data" | gcloud secrets create my-secret \
    --replication-policy="replication-policy" \
    --data-file=-

Dengan replication-policy adalah salah satu dari automatic atau user-managed.

Untuk mengakses konten versi secret tertentu:

$ gcloud secrets versions access 1 --secret="my-secret"

Untuk mengakses konten versi secret terbaru:

$ gcloud secrets versions access latest --secret="my-secret"

C#

Untuk menjalankan kode ini, pertama-tama siapkan lingkungan pengembangan C# dan instal Secret Manager C# SDK. Di Compute Engine atau GKE, Anda harus melakukan autentikasi dengan cakupan cloud-platform.

        SecretManagerServiceClient client = SecretManagerServiceClient.Create();

        // Build the parent project name.
        ProjectName projectName = new ProjectName(projectId);

        // Build the secret to create.
        Secret secret = new Secret

API

Contoh ini menggunakan curl untuk menunjukkan penggunaan API. Anda dapat membuat token akses dengan gcloud auth print-access-token. Di Compute Engine atau GKE, Anda harus melakukan autentikasi dengan cakupan cloud-platform.

Untuk membuat secret dan menyimpan string sebagai konten versi secret:

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets?secretId=my-secret" \
    --request "POST" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \
    --header "content-type: application/json" \
    --data "{\"replication\": {\"automatic\": {}}}"

Untuk mengakses konten versi secret:

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets/my-secret/versions/1:access" \
    --request "GET" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \
    --header "content-type: application/json"
