Gérer l'accès aux secrets

Cette rubrique explique comment gérer l'accès à un secret, y compris au matériel secret. Pour en savoir plus sur le contrôle des accès et les autorisations, consultez la documentation IAM de Secret Manager.

Important : Pour utiliser Secret Manager avec des charges de travail exécutées sur Compute Engine ou Google Kubernetes Engine, l'instance ou le nœud sous-jacent doit disposer du champ d'application OAuth cloud-platform. Pour en savoir plus, consultez la section Accéder à l'API Secret Manager.

Rôles requis

Pour gérer l'accès à un secret, vous devez disposer du rôle d'administrateur Secret Manager (roles/secretmanager.admin) au niveau du secret, du projet, du dossier ou de l'organisation.

Accorder l'accès

Console

Accédez à la page Secret Manager dans la console Google Cloud.

Accéder à la page Secret Manager
Sur la page Secret Manager, cochez la case située à côté du nom du secret.
S'il n'est pas déjà ouvert, cliquez sur Afficher le panneau d'informations pour ouvrir celui-ci.
Dans le panneau d'informations, cliquez sur Ajouter un compte principal.
Dans la zone de texte Nouveaux comptes principaux, saisissez la ou les adresses e-mail des membres à ajouter.
Dans la liste déroulante Sélectionner un rôle, sélectionnez Gestionnaire de secrets, puis Accesseur de secrets Secret Manager.

gcloud

Pour utiliser Secret Manager dans la ligne de commande, commencez par installer la Google Cloud CLI ou passer à la version 378.0.0 ou ultérieure. Sur Compute Engine ou GKE, vous devez vous authentifier avec le champ d'application cloud-platform.

$ gcloud secrets add-iam-policy-binding secret-id \
    --member="member" \
    --role="roles/secretmanager.secretAccessor"

Où member correspond à un membre IAM, tel qu'un utilisateur, un groupe ou un compte de service.
