Cette page explique comment accorder une autorisation binaire aux règles et aux images de conteneurs existant dans des projets Google Cloud différents de votre projet actuel.
Par exemple, si vous déployez des images dans votre cluster Google Kubernetes Engine (GKE) à partir d'un dépôt Artifact Registry ou Container Registry (obsolète) appartenant à un autre projet, vous devez accorder au service d'autorisation binaire de votre projet l'accès aux métadonnées d'image dans le dépôt source.
Terminologie
Ce document utilise les termes suivants :
Agent de service : compte de service géré par Google Cloud.
L'autorisation binaire utilise un agent de service pour interagir avec vos ressources Google Cloud, telles que les clusters GKE.
Projet de règles : projet Google Cloud qui contient votre règle d'autorisation binaire.
Projet de clusters : projet Google Cloud qui contient votre cluster GKE.
Projet d'artefacts : projet Google Cloud contenant votre dépôt Artifact Registry ou Container Registry (obsolète).
Scénarios nécessitant un accès entre projets
Vous devez accorder des autorisations entre projets dans les situations suivantes :
Votre projet de règles est différent de votre projet de clusters.
Votre projet de clusters est différent de votre projet d'artefacts.

Accordez à l'agent de service d'autorisation binaire du projet de clusters le rôle Évaluateur des règles d'autorisation binaire (roles/binaryauthorization.policyEvaluator) sur le projet de règles.
POLICY_PROJECT_ID : ID du projet contenant votre règle.
CLUSTER_PROJECT_ID : ID de projet du cluster.
Projet de clusters différent du projet d'artefacts
Accordez à l'agent de service d'autorisation binaire du projet de clusters le rôle Lecteur Artifact Registry (roles/artifactregistry.reader) sur le projet d'artefacts.
ARTIFACT_PROJECT_ID : ID du projet contenant votre dépôt Artifact Registry.
CLUSTER_PROJECT_ID : ID du projet qui exécute vos clusters GKE.
