memory of nobody

So I have this USD300 credit for two months period to play around with Google compute. I had created an instance, but with very small storage, 10GB. Then I decide nothing much can be done with that, so I created a persistent disk. Google compute's documentation is incomplete and terrible, so we need to do try and error. So this is the confirmed workable solution that I tested: Let say we created a project name "blah-1234" and a persistent disk name "disk-for-blah" to be attached to a VM instance named "vm-blah" Please replace the --zone ~$ gcloud compute instances attach-disk --project "blah-1234" vm-blah  --disk disk-for-blah --zone asia-east1-c If everything is fine (it'll take few seconds for the disk to be attached. You'll be prompted with the following output) : Updated [https://www.googleapis.com/compute/v1/projects/blah-1234/zones/asia-east1-c/instances/vm-blah].
