Here’s how to list GCP instances with a specific service account.
gcloud compute instances list \ --project your-project-id \ --format="value(name,serviceAccounts[].email)" \ --filter="serviceAccounts.email=your-service-account@email.com AND name~\bwp" |
I’m using filters to look for a specific service account, and any instance starting with ‘wp.’ \b means begins with.
Here’s how to list reservations in GCP.
gcloud compute reservations list --project project-id |
Specify a zone.
gcloud compute reservations list \ --filter="zone:('us-central1-a')" \ --project project-id |
Here’s how to identify your disks on the system to cross check with GCP Dashboard.
ls -l /dev/disk/by-id |
Result:
[root@servername ~]# ls -l /dev/disk/by-id total 0 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 google-boot -> ../../sda lrwxrwxrwx. 1 root root 10 Sep 15 05:30 google-boot-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 google-persistent-disk-1 -> ../../sdb lrwxrwxrwx. 1 root root 9 Sep 15 05:30 scsi-0Google_PersistentDisk_boot -> ../../sda lrwxrwxrwx. 1 root root 10 Sep 15 05:30 scsi-0Google_PersistentDisk_boot-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 9 Sep 15 05:30 scsi-0Google_PersistentDisk_persistent-disk-1 -> ../../sdb |
Here’s how to display a list the disks attached to an instance.
gcloud compute instances describe instance-name \ --project project-id \ --zone us-central1-c \ --format='yaml(disks[].source)' |
Here’s how to create an instance with CUD (committed used discounts) reservations.
gcloud compute instances create instance-name \ --no-address \ --private-network-ip 10.0.0.24 \ --source-machine-image=projects/project-id/global/machineImages/image-name \ --subnet=https://www.googleapis.com/compute/v1/projects/your-project/regions/us-central1/subnetworks/your-sub-network \ --machine-type=n1-standard-4 \ --reservation-affinity=specific \ --reservation=your-reservation-name \ --zone=us-central1-a \ --project=your-project-id |
This will create a CUD (Committed Used Discounts) Reservation in GCP.
gcloud compute reservations create reservation-name-us-central1-a \ --machine-type=n1-standard-4 \ --vm-count=1 \ --zone=us-central1-a \ --require-specific-reservation |
This creates a specific reservation instead of an open reservation.
Here’s how to set the instance scope in GCP.
Stop the server.
gcloud compute instances stop server-name |
Default scopes.
gcloud beta compute instances set-scopes server-name \ --service-account=your-service-account@gserviceaccount.com \ --scopes=default \ --project your-project-id \ --zone=us-central1-a |
Change scopes by adding storage-rw to default.
gcloud alpha compute instances set-scopes servername \ --service-account=your-service-account@gserviceaccount.com \ --scopes=default,storage-rw \ --project your-project-id \ --zone=us-central1-c |
Start the server.
gcloud compute instances start server-name |

Go to Logging > Logs Viewer to monitor a GCP Load Balancer.

When trying to boot from a disk created from snapshot and you’re getting an “UEFI feature is not available for this project” error, you’ll need to create a boot image with the –guest-os-features option set to “UEFI_COMPATIBLE.”
gcloud compute disks create new-server-disk-2 \ --project=project-name \ --source-snapshot=server-disk-2 \ --zone=us-central1-b \ --guest-os-features="UEFI_COMPATIBLE" |
It’s about enabling guest operating system features on custom images. The guest operating system features let you configure networking, security, storage, and operating system options on custom images to be used on boot disks.
Here’s how to display a list of Google Cloud forwarding rules.
gcloud compute forwarding-rules list |
If you want global only.
gcloud compute forwarding-rules --global |
Or just local regions only.
gcloud compute forwarding-rules --filter="region:( us-central us-west1 )" |
