GCP Create Images

Here’s how to create a GCP Disk Image from a Boot Drive.

  • First, stop the instance.
  • If you can’t, stop the applications/database from writing to disks.
  • Run sudo sync .

Create From Disk

gcloud compute images create the-new-image-name \
   --source-disk the-source-boot-disk \
   --source-disk-zone us-central1-a \
   --family the-image-family \
   [--force]

Create From Image

gcloud compute images create the-new-image-name \
  --source-image the-source-image \
  --source-image-project the-project-where-the-image-is-located \
  --family the-image-family

Create From Snapshot

gcloud compute images create the-new-image-name \
  --source-snapshot the-source-snapshot

GCP Create Disk from Snapshot

Here’s how to create a disk from a snapshot via Google SDK.

--project=project-name \
--source-snapshot=server-disk-2 \
--zone=us-central1-b

Encrypt Volume via Terraform

Here’s the Terraform script to encrypt an unencrypted volume. It creates a snapshot, encrypts a snapshot, and encrypts the volume.

#
# Set Variables
#
variable "volume" {
  description = "The Volume to encrypt: vol-12345678901234567"
}
variable "region" {
  description = "The Region: us-east-2"
}
variable "az" {
  description = "The AZ: us-east-2a"
}
 
#
# Set Credentials
#
provider "aws" {
	access_key = "put-your-access-key-here"
	secret_key = "put-your-secret-key-here"
	region = "${var.region}"
}
 
/*
#
# Create Unencrypted Volume
#
resource "aws_ebs_volume" "unencrypted_volume" {
  availability_zone = "${var.az}"
  size              = 10
  tags = {
    Name = "Unencrypted_Volume"
  }
}
*/
 
#
# Create Unencrypted Snapshot
#
resource "aws_ebs_snapshot" "unencrypted_snapshot" {
  #volume_id = "${aws_ebs_volume.unencrypted_volume.id}"
  volume_id = "${var.volume}"
  tags = {
    Name = "Unencrypted_Snapshot"
  }
}
 
#
# Create Encrypted Snapshot
#
resource "aws_ebs_snapshot_copy" "encrypted_snapshot" {
  source_snapshot_id = "${aws_ebs_snapshot.unencrypted_snapshot.id}"
  source_region      = "${var.region}"
  encrypted = true
  tags = {
    Name = "Encrypted_Snapshot"
  }
}
 
#
# Created Encrypted Volume
#
resource "aws_ebs_volume" "encrypted_volume" {
  availability_zone = "${var.az}"
  snapshot_id = "${aws_ebs_snapshot_copy.encrypted_snapshot.id}"
  tags = {
    Name = "Encrypted_Volume"
  }
}

Steps to Encrypt Volumes

Here the steps to encrypt an unencrypted volume.

  1. Take a snapshot of the unencrypted volume.
  2. Make a copy of that snapshot and turn on encryption.
  3. Create a volume of the encrypted snapshot.
  4. Stop the instance.
  5. Detach the original unencrypted volume from the instance.
  6. Attach the newly created encrypted volume to the instance.
  7. Start the instance.
