Here’s how to create an internal IP reservation in GCP.
gcloud compute addresses create my-private-ip-reservation \ --addresses 10.128.0.15 \ --region us-central1 \ --subnet default \ --project project-id |
gcloud compute addresses create my-private-ip-reservation \ --addresses 10.128.0.15 \ --region us-central1 \ --subnet default \ --project project-id
To list your reserved IPs.
gcloud compute addresses list \
--project project-id |
gcloud compute addresses list \ --project project-id
I’ve been using this keyboard for a few years, but never knew how to use page and page down. It’s …
fn + up arrow = page up fn + down arrow = page down |
fn + up arrow = page up fn + down arrow = page down
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" |
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 |
gcloud compute reservations list --project project-id
Specify a zone.
gcloud compute reservations list \ --filter="zone:('us-central1-a')" \ --project project-id |
gcloud compute reservations list \ --filter="zone:('us-central1-a')" \ --project project-id
In Windows a new line, is a CR (carriage return) followed by LF (line feed). In Linux, it’s just LF. If you bring over a text file from Windows to Linux, sometimes you’ll end up with a file with a bunch of ^M at the end of each line, which will breaks a lot of things. To fix, just run dos2unix.

Here’s how to identify your disks on the system to cross check with GCP Dashboard.
ls -l /dev/disk/by-id |
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)' |
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 |
