Gestire l'accesso ai secret

Questa pagina descrive come gestire l'accesso a un segreto, incluso il materiale segreto. Per scoprire di più sui controlli di accesso e sulle autorizzazioni, consulta Controllo dell'accesso con IAM.

Ruoli obbligatori

Per ottenere le autorizzazioni necessarie per gestire l'accesso ai secret, chiedi all'amministratore di concederti il ruolo IAM Amministratore Secret Manager (roles/secretmanager.admin) per il secret, il progetto, la cartella o l'organizzazione. Per ulteriori informazioni sulla concessione dei ruoli, consulta Gestire l'accesso a progetti, cartelle e organizzazioni.

Potresti anche riuscire a ottenere le autorizzazioni richieste tramite i ruoli personalizzati o altri ruoli predefiniti.

Concedi l'accesso

Per concedere l'accesso a una secret, utilizza uno dei seguenti metodi:

Console

  1. Nella console Google Cloud, vai alla pagina Secret Manager.

    Vai a Secret Manager

  2. Per selezionare un segreto, fai clic sulla casella di controllo accanto al nome del segreto nella pagina Secret Manager.

  3. Se non è già aperto, fai clic su Mostra riquadro informazioni per aprirlo.

  4. Nel riquadro delle informazioni, fai clic su Aggiungi entità.

  5. Nel campo Nuovi principali, inserisci gli indirizzi email dei membri da aggiungere.

  6. Nell'elenco Seleziona un ruolo, scegli Secret Manager e poi Accesso ai segreti di Secret Manager.

gcloud

Prima di utilizzare i dati dei comandi riportati di seguito, effettua le seguenti sostituzioni:

  • SECRET_ID: l'ID della secret o l'identificatore completo della secret
  • MEMBER: il membro IAM, ad esempio un utente, un gruppo o un service account

Esegui il seguente comando:

Linux, macOS o Cloud Shell

gcloud secrets add-iam-policy-binding SECRET_ID \
    --member="MEMBER" \
    --role="roles/secretmanager.secretAccessor"

Windows (PowerShell)

gcloud secrets add-iam-policy-binding SECRET_ID `
    --member="MEMBER" `
    --role="roles/secretmanager.secretAccessor"

Windows (cmd.exe)

gcloud secrets add-iam-policy-binding SECRET_ID ^
    --member="MEMBER" ^
    --role="roles/secretmanager.secretAccessor"

REST

Nota: a differenza degli altri esempi, questo sostituisce l'intero criterio IAM.

Prima di utilizzare i dati della richiesta, apporta le seguenti sostituzioni:

  • PROJECT_ID: il Google Cloud progetto che contiene il segreto
  • SECRET_ID: l'ID della secret o l'identificatore completo della secret
  • MEMBER: il membro IAM, ad esempio un utente, un gruppo o un service account

Metodo HTTP e URL: 

POST https://secretmanager.googleapis.com/v1/projects/PROJECT_ID/secrets/SECRET_ID:setIamPolicy

Corpo JSON della richiesta: 

{"policy": {"bindings": [{"members": ["MEMBER"], "role": "roles/secretmanager.secretAccessor"}]}}

Per inviare la richiesta, scegli una delle seguenti opzioni:

curl

Salva il corpo della richiesta in un file denominato request.json, quindi esegui il comando seguente: 

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

PowerShell

Salva il corpo della richiesta in un file denominato request.json, quindi esegui il comando seguente: 

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

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

Dovresti ricevere una risposta JSON simile alla seguente:
