Creating, deleting, and deprecating custom images

You can create custom images from source disks, images, snapshots, or images stored in Cloud Storage. You can use these images to create virtual machine (VM) instances. This is ideal for situations where you have created and modified a persistent boot disk or specific image to a certain state and need to save that state for creating instances.

Alternatively, you can use the virtual disk import tool to import boot disk images to Compute Engine from your existing systems and add them to your custom images list.

Before you begin

If you want to use the command-line examples in this guide:
1. Install or update to the latest version of the gcloud command-line tool.
2. Set a default region and zone.
If you want to use the API examples in this guide, set up API access.
Read the Images page.

Creating a custom image

These instructions describe how to create a custom image on a Linux instance. For instructions for creating a Windows image, see Creating a Windows image.

You must use Cloud Identity and Access Management (Cloud IAM) permissions to share images with other projects.

Selecting an image storage location

When creating a custom image, you can specify the image's Cloud Storage location, excluding dual-region locations. By specifying the image storage location, you can meet your regulatory and compliance requirements for data locality as well as your high availability needs by ensuring redundancy across regions.

The storage location feature is optional. If you do not select a location, Compute Engine stores your image in the multi-region closest to the image source.

To see the location where an image is currently stored, use the images describe command from gcloud beta compute:

gcloud beta compute images describe [IMAGE_NAME] --project [PROJECT]

⋮
storageLocations:
- us-central1

All of your existing images prior to this feature launch remain where they are. The only change is that you can view the image location of all your images. If you have an existing image you want to move, you must recreate it in the desired location.

Preparing your instance for an image

You can create an image from a disk even while it is attached to a running VM instance. However, your image will be more reliable if you put the instance in a state that is easier for the image to capture. Use one of the following processes to prepare your boot disk for the image:

Stop the instance so that it can shut down and stop writing any data to the persistent disk.
If you can't stop your instance before you create the image, minimize the amount of writes to the disk and sync your file system.
1. Pause apps or operating system processes that write data to that persistent disk.
2. Run an app flush to disk if necessary. For example, MySQL has a FLUSH statement. Other apps might have similar processes.
3. Stop your apps from writing to your persistent disk.
4. Run sudo sync.

After you prepare the instance, create the image.

Creating the image

You can create disk images from the following sources:

A persistent disk, even while that disk is attached to an instance
A snapshot of a persistent disk
Another image in your project
An image that is shared from another project
A compressed RAW image in Cloud Storage

Console

In the Google Cloud Platform Console, go to the Create an image page.
Go to the Create an image page
Specify the Name of your image.
Specify the Source from which you want to create an image. This can be a persistent disk, a snapshot, another image, or a disk.raw file in Cloud Storage.
Specify the Location at which to store your image. Choose your image storage location from the Based on source disk location (default) drop-down list. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you don't make a selection, Compute Engine stores the image in the multi-region closest to your image's source location.
Specify the properties for your image. For example, you can specify an image family name for your image to organize this image as part of an image family.
Click Create to create the image.

gcloud

In the gcloud command-line tool, use the gcloud compute beta images create command to create a custom image. The beta tag is required for the optional --storage-location flag.

Create an image from a source disk:

gcloud beta compute images create [IMAGE_NAME] \
  --source-disk [SOURCE_DISK] \
  --source-disk-zone [ZONE] \
  --family [IMAGE_FAMILY] \
  --storage-location [LOCATION] \
  --force

[IMAGE_NAME] is a name for the new image.
[SOURCE_DISK] is the disk from which you want to create the image.
[ZONE] is the zone where the disk is located.
[IMAGE_FAMILY] is an optional flag that specifies which image family this image belongs to.
[LOCATION] is an optional flag that lets you designate the region or multi-region where your image is going to be stored. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you don't make a selection, Compute Engine stores the image in the multi-region closest to your image's source location.
[--force] is an optional flag that allows you to create the image from a running instance. By default, you cannot create images from running instances. Specify this flag only if you are sure that you want to create the image while the instance is running.

Create an image from a source image:

gcloud beta compute images create [IMAGE_NAME] \
  --source-image [SOURCE_IMAGE] \

[IMAGE_FAMILY] is an optional flag that specifies which image family this new image belongs to.
[LOCATION] is an optional flag that allows you to designate the region or multi-region where your image is going to be stored. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you do not make a selection, Compute Engine will store the image in the multi-region closest to your image's source location.

Create an image from a snapshot:

gcloud beta compute images create [IMAGE_NAME] \
  --source-snapshot [SOURCE_SNAPSHOT] \
  --storage-location [LOCATION]

where:

[IMAGE_NAME] is a name for the new image.
[SOURCE_SNAPSHOT] is the snapshot from which you want to create the image.
[LOCATION] is an optional flag that allows you to designate the region or multi-region where your image is going to be stored. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you do not make a selection, Compute Engine will store the image in the multi-region closest to your image's source location.

View an image location:

Use the gcloud beta compute images describe command to view an image location. The beta tag is required to see the image's storage location.

gcloud beta compute images describe [IMAGE_NAME]

where [IMAGE_NAME] is the name of your image that you want described.

API

Make a POST request to the images().insert method, a URL in the request body that points to the source object from which you want to create the image. Specify URLs to your resources using your own project ID and resource names. Use the beta version of this method to specify the storageLocations parameter.

For more information about adding images, see the images reference.

Deprecating an image

Compute Engine lets you deprecate a custom image that you own by setting the deprecation status on the image. Each deprecation status causes a different response from the server, helping you transition users away from unsupported images in a manageable way. Use the console, gcloud command, or the Compute Engine API method to deprecate an image.

Console

In the Google Cloud Platform Console, go to the Create an image page.
Go to the Create an image page
Check the box to the left of the image you want to deprecate.
Click Deprecate at the top of the page. Your image is deprecated.

gcloud

Use the gcloud compute images deprecate command to set the deprecation status of an image.

gcloud compute images deprecate [IMAGE_NAME] \
    --state [STATE] \
    --replacement [REPLACEMENT]

where, [IMAGE_NAME] is the name of the image to deprecate.

The deprecation state can be any of:

DEPRECATED - This image is considered deprecated. When users attempt to use this image, the request will succeed but Compute Engine also returns a warning. New links to this image are still allowed. Image families no longer point to this image even if it is the most recent image in a family.
OBSOLETE - This image is obsolete and new users cannot use it. Compute Engine returns an error if users try to use the image in their requests. Existing links to this image are still allowed.
DELETED - This image is deleted and users cannot use it. Compute Engine returns an error if users attempt to use the image.

API

Make a POST request to the images().deprecate method. Specify the name of the image you want to deprecate.

POST https://www.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/images/[RESOURCE_ID]/deprecate

{
  "deprecated": "[IMAGE_NAME]",
  "replacement": "[REPLACEMENT]"
}

where:

[PROJECT_ID] is the project to which the image belongs.
[IMAGE_NAME] the image you are deprecating.
[REPLACEMENT] the image to replace the one that is deprecated.

Deleting an image

You can only delete custom images that you, or someone who has access to the project, have added. Use the console, gcloud command, or the Compute Engine API method to delete the image.

Console

In the Google Cloud Platform Console, go to the Create an image page.
Go to the Create an image page
Check the box to the left of the image you want to delete.
Click Delete at the top of the page. Your image is deleted.

gcloud

Use the gcloud compute images delete command to delete an image.

gcloud compute images delete [IMAGE_NAME]

where [IMAGE_NAME] is the name of the image to delete.

API

Make a POST request to images().delete method. Specify the name of the image you want to delete.

POST https://www.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/images/[RESOURCE_ID]

where:

[PROJECT_ID] is the project to which the image belongs.
[RESOURCE_ID] is a name for the image that you want to delete.

Setting image versions in an image family

Use image families to simplify image versioning. Add an image to an image family to set it as the most recent image version. If you determine that you must roll back the image family to a previous image version, deprecate the most recent image in the family.

Optionally, you can specify the image's storage location, using the console, the gcloud beta compute images create command with the --storageLocation flag, or the beta images().insert API method.

For example, create an image named image-v1 as part of an image family.

Console

In the Google Cloud Platform Console, go to the Create an image page.
Go to the Create an image page
Specify the Name of your image.
Specify the Source from which you want to create an image. This can be a persistent disk, a snapshot, another image, or a disk.raw file in Google Cloud Storage.
Specify the Location where you will store your image. Choose your image storage location from the Based on source disk location (default) drop-down menu. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you do not make a selection, Compute Engine will store the image in the multi-region closest to your image's source location.
Specify the properties for your image. For example, you can specify the image family name my-image-family for your image to organize this image as part of an image family.
If you are creating an image from a disk attached to a running image, check "Force creation from running instance" to confirm that you want to create the image while the instance is running.
Click Create to create the image.

gcloud

gcloud compute images create image-v1 \
    --source-disk disk-1 \
    --source-disk-zone us-central1-f \
    --family my-image-family \

The image family points to image-v1. Add a second image to the family:

gcloud compute images create image-v2 \
    --source-disk disk-2 \
    --source-disk-zone us-central1-f \
    --family my-image-family \

API

Make a POST request to the images().insert method. Specify the image family in the request body.

POST https://www.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/images

{
  "name": "image-v2",
  "sourceDisk": "/zones/us-central1-f/disks/disk-2",
  "family":"my-image-family",

}

The image family points to image-v2 because it is the most recent image that you added to the image family.

gcloud

You can see which image a family points to by running the gcloud compute images describe-from-family command.

For example:

gcloud beta compute images describe-from-family my-image-family

family: my-image-family
id: '8904691942610171306'
kind: compute#image
name: image-v2
selfLink: https://www.googleapis.com/compute/v1/projects/my-project/global/images/image-v2
sourceDisk: https://www.googleapis.com/compute/v1/projects/my-project/zones/us-central1-f/disks/disk-v2
sourceDiskId: '1677449456001963379'
sourceType: RAW
status: READY

API

Make a GET request to the images().getFromFamily method. Specify the image family in the request body.

GET https://www.googleapis.com/compute/v1/projects/[PROJECT_ID]/global/images/family

{
  "resourceId":"my-image-family",

}

If you determine that you must roll back the image family so that it no longer points to image-v2, deprecate image-v2 and the family will again point to image-v1.

gcloud compute images deprecate image-v2 \
    --state DEPRECATED \
    --replacement image-v1

Check to make sure that the image family is pointing to image-v1.

gcloud beta compute images describe-from-family my-image-family

family: my-image-family
id: '2741732787056801255'
kind: compute#image
name: image-v1
selfLink: https://www.googleapis.com/compute/v1/projects/my-project/global/images/image-v1
sourceDisk: https://www.googleapis.com/compute/v1/projects/my-project/zones/us-central1-f/disks/disk-v1
sourceDiskId: '1677449456001963379'
sourceType: RAW
status: READY

Enabling guest operating system features on custom images

You can set the guestOsFeatures parameter when you create a custom image. This parameter enables one or more features for VM instances that use the image for their boot disks. The following features are available:

MULTI_IP_SUBNET. For configuring interfaces with a netmask other than /32.
SECURE_BOOT. Enables UEFI secure boot, which restricts unsigned software from booting or unsigned drivers from loading on the VM instance. After you set this parameter, you can then enable the secure boot feature during VM instance creation.
UEFI_COMPATIBLE. Enables UEFI booting, which is an alternative system boot method. Most public images use the GRUB bootloader as their primary boot method.
VIRTIO_SCSI_MULTIQUEUE. Enables multiqueue SCSI capabilities for Local SSD devices. This option is an alternative to NVMe.
- For Linux images, you can enable VIRTIO_SCSI_MULTIQUEUE on images with kernel versions 3.17 and later.
- For Windows images, you can enable VIRTIO_SCSI_MULTIQUEUE on images with driver version 1.2.0.1621 or higher.
WINDOWS. Required for Windows Server images. Newer public images for Windows Server include the WINDOWS parameter to indicate that it is a Windows image.

Use the gcloud command-line tool or the API to enable guest operating system features on your custom images.

gcloud

Use the gcloud compute images create command to create a custom image from one of your existing custom images, but also include the --guest-os-features flag. Use the gcloud compute beta images create command to include the optional --storage-location flag.

gcloud beta compute images create [IMAGE_NAME] \
  --source-image [SOURCE_IMAGE] \
  --source-image-project [IMAGE_PROJECT] \
  --guest-os-features="[FEATURE_ID],..." \
  --storage-location [LOCATION]

where:

[IMAGE_NAME] is a name for the new image that you want to create.
[SOURCE_IMAGE] is the image from which you want to create the image.
[IMAGE_PROJECT] is an optional parameter that specifies which project the source image is located in. Use this parameter if you want to copy an image from another project.
[FEATURE_ID] is an ID for one of the available guest OS features. You can specify multiple features as a comma-separated list.
[LOCATION] is an optional flag that lets you designate the region or multi-region where your image is going to be stored. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you don't make a selection, Compute Engine stores the image in the multi-region closest to your image's source location.

API

Make a POST request to the images().insert method, a URL in the request body that points to the source object from which you want to create the image. Replace the project and zone with your own project ID and the zone of the persistent disk. Use the beta API method for this request to see the storageLocations parameter.

Create an image from a persistent disk:

POST https://www.googleapis.com/compute/beta/projects/[PROJECT_ID]/global/images

{
 "name": "[IMAGE_NAME]",
 "sourceImage": "projects/[IMAGE_PROJECT]/global/images/[SOURCE_IMAGE]",
 "storageLocations": "[LOCATION]",
 "guestOsFeatures": [
  {
   "type": "[FEATURE_ID]"
  }
 ]
}

where:

[IMAGE_NAME] is a name for the new image that you want to create.
[SOURCE_IMAGE] is the image from which you want to create the image.
[IMAGE_PROJECT] is a parameter that specifies which project the source image is located in.
[LOCATION] is an optional parameter that lets you select the storage location of your image. For example, specify us to store the image in the us multi-region, or us-central1 to store it in the us-central1 region. If you don't make a selection, Compute Engine stores the image in the multi-region closest to your image's source location.
[FEATURE_ID] is an ID for one of the available guest OS features. You can specify multiple features as a comma-separated list.
