Questa pagina mostra come concedere l'accesso all'autorizzazione binaria a criteri e immagini container che esistono in progetti Google Cloud diversi dal tuo progetto attuale.
Ad esempio, se esegui il deployment di immagini nel cluster Google Kubernetes Engine (GKE)
da un repository Artifact Registry o Container Registry (ritirato)
di proprietà di un altro progetto, devi concedere al servizio di autorizzazione binaria nel tuo progetto l'accesso ai metadati dell'immagine nel repository di origine.
Terminologia
Questo documento utilizza i seguenti termini:
Agente di servizio : account di servizio gestito da Google Cloud.
Autorizzazione binaria utilizza un service agent per interagire con le tue risorse, come i cluster GKE. Google Cloud
Progetto policy: il progetto che contiene la policy di autorizzazione binaria. Google Cloud
Progetto cluster: il progetto Google Cloud che contiene il tuo
cluster GKE.
Progetto artefatto : il progetto Google Cloud che contiene il tuo repository Artifact Registry o Container Registry (deprecato).
Scenari che richiedono l'accesso tra progetti
Devi concedere le autorizzazioni tra progetti in situazioni come le seguenti:
Il progetto delle norme è diverso dal progetto del cluster.
Il progetto del cluster è diverso dal progetto dell'artefatto.

Il progetto del cluster è diverso dal progetto del criterio
Concedi all'agente di servizio Autorizzazione binaria nel progetto cluster il ruolo
Valutatore del criterio di autorizzazione binaria
(roles/binaryauthorization.policyEvaluator)
nel progetto dei criteri.
POLICY_PROJECT_ID: l'ID del progetto che contiene la policy.
CLUSTER_PROJECT_ID: l'ID progetto del cluster.
Progetto cluster diverso dal progetto artefatto
Concedi all'agente di servizio Autorizzazione binaria nel progetto cluster il ruolo
Lettore Artifact Registry
(roles/artifactregistry.reader) nel progetto artefatto.
