Creating an image from a volume

Creating an image from a volume

You can create an image from a volume that is attached to an available virtual server instance as a boot volume in the console, from the CLI, or with the API.

Scenarios for creating an image from a volume

You can create an image from a volume in several ways.

  • Select an instance and create an image from that instance's boot volume. The new image inherits the boot volume's encryption (customer-managed or IBM-managed).

  • Select an instance, create an image from that instance's boot volume, and specify a different encryption. For example, if the boot volume was encrypted with IBM-managed encryption, you can select customer-managed encryption for the new image.

  • Create an image from a boot volume from the list of Block Storage volumes. The volume must be a boot volume that is attached to a virtual server instance.

Depending on the size of the image that you're creating, the job might take from 5 minutes to 1.5 hours. You can cancel a job that's taking too long to queue. For more information, see Performance considerations.

Creating an image from a volume in the UI

You can create an image from a volume that is attached to an available virtual server instance as a boot volume in the console.

To create an image of the boot volume, the associated virtual server instance must be stopped.

  1. In the IBM Cloud console, click the Navigation menu icon menu icon > VPC Infrastructure VPC icon > Compute > Images.

  2. On the Custom images tab, click Create. The Custom image for VPC page is displayed.

  3. Complete the required fields on the Import custom images page, and then continue with one of the Source options.

    Table 1. Import custom image user interface fields
    Field Value
    Location Select the geographic area and location where you want your custom image to be available for provisioning.
    Geography Select from the list.
    Region Select from the list.
    Details
    Name A name is required for your custom image.
    Resource group Select a resource group for the image. This selection can't be changed later.
    Tags You can assign a label to this resource so that you can easily filter resources in your resource list.
    Access management tags As the name indicates, these tags can help organize access control without requiring updates to IAM policies. For more information, see Controlling access to resources by using tags.
    Source Select the source for the custom image by choosing either Virtual server instance boot volume (default) or Block Storage boot volume.
  4. Choose your image source:

    • Select the Virtual server instance boot volume as the source of your custom image to display a list of available instances.

      • Select the instance from the list.
      • If the instance is running and the volume selector is disabled, click the Actions icon Actions icon and select Stop.
    • Select a Block Storage boot volume as the source of your custom image to display a list of available boot volumes.

      • Select the volume from the list.
      • If the volume selector is disabled, click the Actions icon Actions icon and select Stop attached instance.
  5. Select your encryption type, either IBM-managed encryption or customer-managed encryption.

    • The default selection is Provider managed. This encryption uses IBM-managed keys. You can't remove encryption later.
    • If you want to create an image that uses your own keys for encryption select the key management service where your customer root key (CRK) that protects your passphrase is stored: either Key Protect or Hyper Protect Crypto Services. Then, you can specify your key in two ways.
      • Locate by instance
        1. Select your key management service instance from the list.
        2. Select your key. If you don't have a key available, click Create to make one.
      • Locate by CRN
        1. Enter the CRN of your encryption key.
  6. Advanced options: You can use the toggle to activate Image lifecycle Management. By selecting this option, you can manage when your image becomes deprecated and obsolete. You can schedule a single status change or schedule the complete lifecycle of the images. You can schedule status changes by using calendar date and time or number of days. The obsolescence date must always be after the deprecation date. For more information, see https://cloud.ibm.com/docs/vpc?topic=vpc-planning-custom-images&interface=ui#custom-image-lifecycle.

  7. On the right-side panel, click Create custom image.

Viewing and using your custom image

When the image is created, it appears in the list of custom images.

  1. In the IBM Cloud console, go to the menu menu icon > VPC Infrastructure VPC icon > Compute > Images.
  2. On the Custom images tab, click the image name to see the volume from which it was created.
  3. Review the image details. Click the link in the Source section to go to the source volume.

To use this image when you create an instance, select it as the operating system type.

  1. In the IBM Cloud console, go to the menu menu icon > VPC InfrastructureVPC icon > Compute > Virtual server instances.
  2. Click Create. For more information about how to provision a new virtual server instance, see Creating virtual server instances in the UI. For the Operating system, select the Custom image tile.
  3. Click Select custom image and select the image from volume that you created.

Create an image from a volume with the CLI

Use the CLI to create an image from a volume that is attached to an available virtual server instance as the primary boot volume or as a secondary boot volume.

Before you begin

  1. Make sure that you downloaded, installed, and initialized the following CLI plug-ins:

    • IBM Cloud CLI
    • The infrastructure-service plug-in

    For more information, see the CLI Reference.

    After you install the vpc-infrastructure plug-in, set the target to generation 2 by running the command ibmcloud is target --gen 2.

  2. Make sure that you created an IBM Cloud VPC.

Create an image from a boot volume that is attached to an instance

  1. To locate the instance that you want to create an image from, list the instances in the region. Take note of the instance ID in the command output.

    ibmcloud is instances
    
  2. Stop the running instance before you create the image from the volume.

    ibmcloud is instance-stop INSTANCE_ID
    
  3. Run the image-create command to create an image of a boot volume. Specify the ID of the source volume.

    ibmcloud is image-create IMAGE_NAME [--source-volume VOLUME_ID]
    

    See the following example:

    $ ibmcloud is image-create test-ifv-vol1 --source-volume ecc68c2f-96a1-4862-bc86-14f47e5d9ed8

Schedule custom image lifecycle status changes by using the CLI

When you import a custom image by using the command-line interface (CLI), you can also schedule the lifecycle status changes of the IBM Cloud VPC custom image at the same time by using options of the ibmcloud is image-create command.

Specify the name of the custom image to be created by using the IMAGE_NAME variable and the source by using the --source-volume option to indicate that the source is an existing boot volume.

To schedule the deprecate-at or obsolete-at properties, specify a date in the ISO 8601 (YYYY-MM-DDThh:mm:ss+hh:mm) date and time format.

  • YYYY is the four-digit year.
  • MM is the two-digit month.
  • DD is the two-digit day.
  • T separates the date and time information.
  • hh is the two-digit hours.
  • mm is the two-digit minutes.
  • +hh:mm or -hh:mm is the Coordinated Universal Time time zone.

Thus, the date of 30 September 2023 at 8:00 PM in the North American Central Standard time zone (CST) would be 2023-09-30T20:00:00-06:00

When you're scheduling the date and time, you can't use your current date and time. For example, if it is 8:00 AM on 12 June 2024, then the scheduled date and time must be after 8:00 AM on 12 June 2024. If you define both the deprecate-at and obsolete-at dates and times, the deprecate-at date must be after the obsolete-at date and time.

ibmcloud is image-create IMAGE_NAME [--source-volume VOLUME_ID] [--deprecate-at YYYY-MM-DDThh:mm:ss+hh:mm] [--obsolete-at YYYY-MM-DDThh:mm:ss+hh:mm]

Creating an image from a volume with the API

Create custom images from Block Storage for VPC boot volumes programmatically by making calls to the VPC REST APIs. You can list all instances and volumes, then use the details of the specific volume to create the image.

Before you begin

Before you begin, make sure that you set up your API environment.

Creating an image from a boot of an instance with the API

  1. Locate the instance and boot volume that you want to create an image from. Get the list of the available instances with the list instance method.

    curl -X GET "$vpc_api_endpoint/v1/instances?version=2024-06-11&generation=2" -H "Authorization: Bearer $iam_token"
    
  2. Take a note of the instance ID, and use it to retrieve the instance details.

    curl -X GET "$vpc_api_endpoint/v1/instances/$instance_id?version=2024-06-11&generation=2" -H "Authorization: Bearer $iam_token"
    

    The response contains the name, ID, and other details of the boot volume in the volume_attachments section.

    "volume_attachments": [
     {
      "device": {
        "id": "a8a15363-a6f7-4f01-af60-715e85b28141"
        },
      "href": "https://us-south.iaas.cloud.ibm.com/v1/instances/e402fa1b-96f6-4aa2-a8d7-703aac843651/volume_attachments/7389-a8a15363-a6f7-4f01-af60-715e85b28141",
      "id": "a8a15363-a6f7-4f01-af60-715e85b28141",
      "name": "my-boot-volume-attachment",
      "volume": {
        "crn": "crn:[...]",
        "href": "https://us-south.iaas.cloud.ibm.com/v1/volumes/49c5d61b-41e7-4c01-9b7a-1a97366c6916",
        "id": "49c5d61b-41e7-4c01-9b7a-1a97366c6916",
        "name": "my-boot-volume"
        }
      }
    ]
    
  3. If the instance is running, stop it by specifying the stop action in a POST /instances call:

    curl -X POST \
    "$vpc_api_endpoint/v1/instances/{instance-id}/gen/actions?ersion=2024-06-11&generation=2"
    -H "Authorization: Bearer $iam_token"\
    -d '{"type":"stop"}'
    
  4. By using the boot volume ID, create an image. See the following example:

     curl -X POST "$vpc_api_endpoint/v1/images?version=2024-06-11&generation=2" 
     -H "Authorization: Bearer $iam_token" 
     -d '{
          "name": "my-image",
          "source_volume": {"id": "4fec84ef-baf9-405d-bf3b-9d5a60e068f7"}
          }`
    

    In the example response, source_volume indicates the boot volume that is used to create the image. Also, notice that the image encryption appears as none because the source volume used the default IBM-managed encryption. If you used you own root key, the response would show user-managed instead.

       "name": "my-boot-volume"
       }
     }
    

Creating an image from volume and specifying your own encryption key

  1. As described in the previous section, locate the instance, and boot volume information. Stop the instance.

  2. Get your key management service instance ID and root key CRN.

  3. Make an API request to create an image. Specify the volume ID the CRN of the root key as shown in the following example.

    curl -X POST "$vpc_api_endpoint/v1/images?version=2024-06-11&generation=2" 
    -H "Authorization: Bearer $iam_token" 
        -d '{
             "name": "my-encrypted-image",
             "source_volume": {"id": "4fec84ef-baf9-405d-bf3b-9d5a60e068f7"}
             "encryption_key":{"crn":"crn:[...key:...]"
            },
    

    The response includes information about the root key.

Scheduling custom image lifecycle status changes with the API

When you create an image from a volume by using the application programming interface (API), you can schedule the lifecycle status changes of the custom image at the same time.

The name can't be used by another image in the region and names that start with ibm- are reserved for system-provided images. Specify the source.volume subproperty to indicate the source of the image from volume.

To schedule the deprecation_at or obsolescence_at properties, specify a date in the ISO 8601 (YYYY-MM-DDThh:mm:ss+hh:mm) date and time format.

  • YYYY is the four-digit year
  • MM is the two-digit month
  • DD is the two-digit day
  • T separates the date and time information
  • hh is the two-digit hours
  • mm is the two-digit minutes
  • +hh:mm or -hh:mm is the Coordinated Universal Time time zone

Thus, the date of 30 September 2023 at 8:00 PM in the North American Central Standard time zone (CST) would be 2023-09-30T20:00:00-06:00

When you're scheduling the date and time, you can't use your current date and time. For example, if it is 8:00 AM on 12 June 2024, then the scheduled date and time must be after 8:00 AM on 12 June 2024. If you define both the deprecation_at and obsolescence_at dates and times, the obsolescence_at date must be after the deprecation_at date and time.

curl -X POST "$vpc_api_endpoint/v1/images?version=2023-02-21&generation=2"\
-H "Authorization: Bearer $iam_token"\
-d '{
      "name": "test-ifv-boot-volume",
      "source_volume": {
    	  "id": "4fec84ef-baf9-405d-bf3b-9d5a60e068f7"
      },
      "deprecation_at": "2023-03-01T06:11:28+05:30",
      "obsolescence_at": "2023-12-31T06:11:28+05:30"
    }'
