Esegui il pull di un'immagine da un progetto Harbor nel client Docker per scaricare l'immagine container specificata dal registro Harbor sulla tua macchina locale. In questo modo puoi eseguire l'applicazione containerizzata in locale o utilizzarla come immagine di base per creare altre immagini.
Prima di iniziare
Per eseguire il pull di un'immagine con Docker, devi avere accesso a quanto segue:
Il ruolo di identità e accesso necessario. Chiedi all'amministratore IAM dell'organizzazione di concederti il ruolo Visualizzatore istanza Harbor (harbor-instance-viewer).
INSTANCE_URL: l'URL dell'istanza Harbor. Ad esempio,
harbor-1.org-1.zone1.google.gdc.test. puoi ottenere l'URL dell'istanza Harbor utilizzando la
console GDC o gcloud CLI.
HARBOR_PROJECT_NAME: il nome del progetto Harbor. Ad esempio,
my-project.
IMAGE: il nome dell'immagine. Ad esempio, nginx.
TAG: il tag per la versione dell'immagine che vuoi estrarre. Ad esempio,
staging.
IMAGE_DIGEST: il valore hash sha256 dei contenuti dell'immagine. Ogni versione
di un'immagine ha un digest univoco. Nell'interfaccia utente dell'istanza Harbor, fai clic sull'immagine specifica per visualizzarne il digest. Per ulteriori informazioni, vedi
Visualizzare le istanze del registro Harbor.

Ask your Organization IAM Admin to grant you the Harbor Instance Viewer (`harbor-instance-viewer`) role.\n- An account with the `Limited Guest` role from Harbor's role-based access controls. For more information, see [Configure access for APIs and within a Harbor instance](/distributed-cloud/hosted/docs/latest/gdch/platform-application/pa-ao-operations/configure-access-control#configure-access-within-harbor-instance).\n- An existing Harbor project.
