I’m going to assume you have a running instance already. Mine is called test-instance. See Create a cloud instance to see how to create an instance. STEP 1 Creating a volume Create the volume by clicking Compute -> Volumes -> Create Volume. Mine is called test-volume, will be 20 GB large and use the regular storage tier. STEP 2 Attach the volume to the instance After you have created the volume it is time to attach it to your instance.
