Tuttavia, \u00e8 importante notare il passaggio all'utilizzo di ContainerStorageInterface. Gli amministratori che hanno distribuito i propri cluster (non gestiti) in AWS e GCE devono pianificare il passaggio all'uso di CSI Driver per lavorare con volumi persistenti - piuttosto che con driver integrati in Kubernetes. Dovrebbero essere aiutati dalla procedura CSIMigration - aspettiamo una guida passo passo. Gli amministratori che utilizzano altri provider per collegare dischi persistenti devono cercare e leggere la documentazione: nella versione 1.21 si promette di rimuovere definitivamente tutti i driver integrati.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
