Mengakses versi secret regional

Halaman ini menjelaskan cara mengakses versi secret. Mengakses versi secret akan menampilkan konten secret dan metadata tambahan tentang versi secret. Untuk mengakses versi secret menggunakan Google Cloud CLI atau Secret Manager API, Anda harus menentukan ID versi atau alias , jika ditetapkan. Anda juga dapat mengakses versi secret terbaru dengan menentukan latest sebagai ID versi.

Peran yang diperlukan

Guna mendapatkan izin yang diperlukan untuk mengakses versi secret, minta administrator untuk memberi Anda peran IAM Secret Manager Secret Accessor (roles/secretmanager.secretAccessor) di secret. Untuk mengetahui informasi selengkapnya tentang cara memberikan peran, lihat Mengelola akses ke project, folder, dan organisasi.

Anda mungkin juga bisa mendapatkan izin yang diperlukan melalui peran khusus atau peran bawaan lainnya.

Mengakses versi secret

Untuk mengakses secret, gunakan salah satu metode berikut:

Konsol

  1. Di Google Cloud konsol, buka halaman Secret Manager.

    Buka Secret Manager

  2. Di halaman Secret Manager, klik tab Regional secrets, lalu klik secret untuk mengakses versinya.

  3. Di halaman detail secret, di tab Versions, pilih versi secret yang ingin Anda akses.

  4. Klik menu Actions yang terkait dengan versi secret, lalu klik View secret value.

  5. Dialog akan muncul dan menampilkan nilai versi secret. Klik Done untuk keluar dari dialog.

gcloud

Mengakses versi secret

Sebelum menggunakan salah satu data perintah di bawah, lakukan penggantian berikut:

  • VERSION_ID: nama resource versi secret
  • SECRET_ID: ID secret
  • LOCATION: lokasi Google Cloud secret

Jalankan perintah berikut:

Linux, macOS, atau Cloud Shell

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION

Windows (PowerShell)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION

Windows (cmd.exe)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION

Mengakses versi secret biner

Untuk menulis byte mentah ke file, gunakan flag --out-file:

Sebelum menggunakan salah satu data perintah di bawah, lakukan penggantian berikut:

  • VERSION_ID: ID versi secret
  • SECRET_ID: ID secret
  • LOCATION: lokasi Google Cloud secret
  • PATH_TO_SECRET: jalur lengkap (termasuk nama file) tempat Anda ingin menyimpan nilai secret yang diambil

Jalankan perintah berikut:

Linux, macOS, atau Cloud Shell

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --out-file="PATH_TO_SECRET"

Windows (PowerShell)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --out-file="PATH_TO_SECRET"

Windows (cmd.exe)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --out-file="PATH_TO_SECRET"

Mendapatkan byte mentah

Untuk mendapatkan byte mentah, minta Cloud SDK mencetak respons sebagai berenkode base64 dan mendekode:

Sebelum menggunakan salah satu data perintah di bawah, lakukan penggantian berikut:

  • VERSION_ID: ID versi secret
  • SECRET_ID: ID secret
  • LOCATION: lokasi Google Cloud secret

Jalankan perintah berikut:

Linux, macOS, atau Cloud Shell

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --format='get(payload.data)' | tr '_-' '/+' | base64 -d

Windows (PowerShell)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --format='get(payload.data)' | tr '_-' '/+' | base64 -d

Windows (cmd.exe)

gcloud secrets versions access VERSION_ID --secret=SECRET_ID --location=LOCATION --format='get(payload.data)' | tr '_-' '/+' | base64 -d

Respons berisi versi secret.

REST

Mengakses versi secret

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

  • LOCATION: lokasi Google Cloud secret
  • PROJECT_ID: Project ID Google Cloud
  • SECRET_ID: ID secret
  • VERSION_ID: ID versi secret

Metode HTTP dan URL: 

GET https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID/versions/VERSION_ID:access

Meminta isi JSON: 

{}

Untuk mengirim permintaan Anda, pilih salah satu opsi berikut:

curl

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID/versions/VERSION_ID:access"

PowerShell

Simpan isi permintaan dalam file bernama request.json, dan jalankan perintah berikut: 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID/versions/VERSION_ID:access" | Select-Object -Expand Content

Anda akan melihat respons JSON seperti berikut:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID/versions/VERSION_ID",
  "payload": {
    "data": "c2VDcjN0Cg==",
    "dataCrc32c": "3131222104"
  }
}

Mengekstrak secret menggunakan alat jq

payload.data respons adalah konten versi secret berenkode base64. Perintah berikut adalah contoh mengekstrak secret menggunakan alat jq.

  $ curl "https://secretmanager.LOCATION.rep.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/secrets/SECRET_ID/versions/VERSION_ID:access" \
      --request "GET" \
      --header "authorization: Bearer $(gcloud auth print-access-token)" \
      --header "content-type: application/json" \
      | jq -r ".payload.data" | base64 --decode

Konsistensi resource

Di Secret Manager, menambahkan versi secret, lalu langsung mengakses versi secret tersebut berdasarkan nomor versi adalah operasi yang sangat konsisten.

Operasi lain dalam Secret Manager memiliki konsistensi tertunda. Operasi yang memiliki konsistensi tertunda biasanya akan konvergen dalam beberapa menit, tetapi mungkin memerlukan waktu beberapa jam.

Penyebaran izin IAM memiliki konsistensi tertunda. Artinya, pemberian atau pencabutan akses ke secret mungkin tidak langsung berlaku. Untuk mengetahui informasi selengkapnya, lihat Penerapan perubahan akses.
