Configure a server to use a Google snapshot to create a volume and attach it to an instance.
Table of Contents
When you attach a volume to an instance, what you're really doing is creating a volume from that snapshot and attaching the volume to the instance. Technically speaking, you cannot attach a snapshot to a running instance. If you want to attach an existing volume, see Attach a Google Volume to an Instance. The advantage of "attaching a snapshot" to an instance is that you don't have to worry about creating the volume in the correct availability zone. Instead, a volume will be created from the snapshot in the same availability zone as your instance. Another advantage is that by default, the created and attached volume will be deleted when the instance is terminated. If you were to attach an existing volume the old way (instead of attaching a snapshot) the volume would persist and not be deleted.
There are two ways you can attach a Google Snapshot to an instance:
Go to the Volume's tab of the running server. Click the Create/Attach Volume Now button.
Go to Clouds -> Google -> Snapshots and select the snapshot that you want to attach to a server at boot time. You can also attach a snapshot to a stopped server or "Next" server (of a running server) under the Volume's tab.
When you configure a server to attach a snapshot, a volume will be created and attached to the server the next time it is launched/relaunched. Click Create/Attach Volume on boot.
Click Schedule to confirm your selections to attach your volume at the boot time of the selected server.
