Crea un'istanza di macchina virtuale (VM) da un'immagine
del sistema operativo o da un'immagine disco. Questo documento
mostra come determinare l'immagine sistema operativo di origine o l'immagine disco di origine di una VM.
Prima di iniziare
Se non l'hai ancora fatto, configura l'autenticazione.
L'autenticazione verifica la tua identità per l'accesso a Google Cloud servizi e API. Per eseguire
codice o esempi da un ambiente di sviluppo locale, puoi autenticarti su
Compute Engine selezionando una delle seguenti opzioni:
Select the tab for how you plan to use the samples on this page:
Console
When you use the Google Cloud console to access Google Cloud services and
APIs, you don't need to set up authentication.
gcloud
Installa Google Cloud CLI.
Dopo l'installazione,
inizializza Google Cloud CLI eseguendo il seguente comando:
Visualizza l'immagine del sistema operativo di origine o l'immagine del disco di origine di una VM
Per visualizzare l'immagine del sistema operativo di origine o l'immagine del disco di origine di una VM, utilizza la
consoleGoogle Cloud , Google Cloud CLI o l'API Compute Engine.
Autorizzazioni richieste per questa attività
Per eseguire questa attività, devi disporre delle seguenti
autorizzazioni:
compute.instances.get sull'istanza
Console
Nella console Google Cloud , vai alla pagina Istanze VM.
Visualizza l'immagine sistema operativo di origine o l'immagine disco di origine del disco utilizzando il
seguente comando
gcloud compute disks describe:
DISK_NAME: il nome del disco di cui visualizzare l'origine.
ZONE: la zona in cui si trova il disco.
SOURCE: un valore che specifica se restituire l'immagine del sistema operativo di origine o l'immagine disco di origine. Da impostare su sourceDisk
o su sourceImage. Non viene restituito alcun valore quando si specifica sourceDisk
o sourceImage, a meno che non esista un'immagine del sistema operativo di origine o un'immagine del disco di origine corrispondente. Se non viene restituito alcun valore, specifica l'altro valore ed esegui di nuovo il comando.
REST
Visualizza i dischi collegati a una VM utilizzando il seguente
metodo instances.get:
GET https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/VM_NAME
Sostituisci quanto segue:
PROJECT_ID: l'ID progetto
ZONE: la zona che contiene la VM
VM_NAME: il nome della VM
Visualizza l'immagine sistema operativo di origine o l'immagine disco di origine del disco utilizzando il
metodo disks.get.
Per una VM con un'immagine sistema operativo di origine, questo metodo restituisce l'immagine di origine
utilizzata per creare il disco nel campo sourceImage. Per una VM
con un'immagine disco di origine, questo metodo restituisce invece l'immagine
di origine nel campo sourceDisk.
