Scripts

  • 01_create_debian.sh : Create service account and Compute Engine virtual machine instance
  • 10_ssh_debian.sh : SSH into a Linux virtual machine instance
  • 20_install_debian_packages.sh : SSH into a Linux virtual machine instance and install packages
  • 99_delete_debian.sh : Delete Compute Engine virtual machine instance and service account
  • ZZ_debug.sh : For debugging only

Snapshots

If you don't need your VM for a long time you can make a snapshot from the disk. You can then delete the VM and the disk (99_delete_debian.sh). If you need the VM with the data again, you can create a new fresh VM from the snapshot.

  • 30_create_snapshot_debian.sh : Create snapshot of Compute Engine persistent boot disk
  • 31_create_from_snapshot_debian.sh : Create Compute Engine persistent boot disk from last snapshot and create virtual machine instance with created disk
  • 39_delete_snapshots_debian.sh : Delete all Compute Engine boot disk snapshots from specific instance

You will then save the disk cost and pay only the very cheap snapshot price.

  • Regional snapshot storage $0.029 per GB in europe-north1 (Finland)
  • Multi-regional snapshot storage $0.0286 per GB in eu (European Union) [DEFAULT]

Example:

# Create snapshot
bash 30_create_snapshot_debian.sh
# Delete SA, Disk and VM
bash 99_delete_debian.sh
# Later, create new VM from snapshot
bash 31_create_from_snapshot_debian.sh
# Delete all snapshots
bash 39_delete_snapshots_debian.sh
