GCP UEFI Compatible

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.

GCP Display Forwarding Rules

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 )"

GCP Create Firewall with Tags

Here’s another way to create a firewall in GCP using network tag as targets.

gcloud compute firewall-rules create "firewall-name" \
    --description="egress rule to allow port 8000 to destination" \
    --priority "1000" \
    --direction EGRESS \
    --action allow \
    --network "your-network" \
    --target-tags="your-network-tag" \
    --destination-ranges="10.0.0.1/32" \
    --rules tcp:8000
