Listing Images

UICLITerraform

To get a list of all images in a region you can click on the Images icon in the sidebar.

The list also allows you to quickly launch a server or create a volume from an image by using option.

Usage

Example

Creating an Image

Images can be created in two ways

By uploading an image file
By converting a volume snapshot to an image

Uploading an Image

UICLITerraform

Info

There is currently no support for uploading images using the UI. Please refer to the CLI description for this task.

Configure CLI

Usage

openstack image create  [--container-format <container-format>]
                        [--disk-format <disk-format>]
                        [--min-disk <disk-gb>] [--min-ram <ram-mb>]
                        [--file <file>] [--volume <volume>] [--force]
                        [--protected | --unprotected]
                        [--public | --private] [--property <key=value>]
                        [--tag <tag>] [--project <project>]
                        [--project-domain <project-domain>]
                        <image-name>

<container-format>: Image container format; default: bare
<disk-format>: Image disk format; default: raw
<disk-gb>: Minimum disk size needed to boot image, in GB
<ram-mb>: Minimum RAM size needed to boot image, in MB
<file>: Path of local image file to be uploaded
--protected | --unprotected: Protects / Unprotects image from deletion
--public | --private: Controls whether image will be visible to the public or not
<key=value>: Sets a property on the image; Can be repeated
<tag>: Sets a tag on the image; Can be repeated
<image-name>: Identifier (name only) of image to be uploaded

OpenStack Terraform Provider

Example:

# Terraform Provider configuration

terraform {
  required_providers {
    openstack = {
      source  = "terraform-provider-openstack/openstack"
    }
  }
}

# Image configuration

resource "openstack_images_image_v2" "ubuntu-orcular" {
  name             = "Ubuntu Oracular Oriole 24.10"
  image_source_url = "https://cloud-images.ubuntu.com/oracular/current/oracular-server-cloudimg-amd64.img"
  container_format = "bare"
  disk_format      = "qcow2"
}

Boot from this image using UEFI firmware

If you want to use UEFI firmware to boot your image, instead of the default BIOS firmware, you need to set two properties on the image:

hw_firmware_type=uefi
hw_machine_type=q35

You can set these either while creating the image or later. The image will now always boot in UEFI mode.

UICLITerraform

Info

There is currently no support for uploading images using the UI. Please refer to the CLI description for this task.

Configure CLI

Options to add when creating the image:

openstack image create --property hw_firmware_type=uefi
                       --property hw_machine_type=q35
                       ... your other arguments ...

Command to add the properties to an existing image:

openstack image set --property hw_firmware_type=uefi
                    --property hw_machine_type=q35
                <image-id>

OpenStack Terraform Provider

Example:

# Terraform Provider configuration

terraform {
  required_providers {
    openstack = {
      source  = "terraform-provider-openstack/openstack"
    }
  }
}

# Image configuration

resource "openstack_images_image_v2" "ubuntu-orcular" {
  name             = "Ubuntu Oracular Oriole 24.10"
  image_source_url = "https://cloud-images.ubuntu.com/oracular/current/oracular-server-cloudimg-amd64.img"
  container_format = "bare"
  disk_format      = "qcow2"

  properties = {
    hw_firmware_type = "uefi"
    hw_machine_type  = "q35"
  }
}

Converting a Volume

Info

Note that the source volume has to be in status AVAILABLE and not IN USE. If this is not the case you can still force the operation in which case the operation can fail or the resulting image may be corrupted.

UICLITerraform

To convert a volume to an image you can

Use the menu in the volumes list and select the Upload to image option
Use the Upload as image option on a volumes detail page

In the emerging dialog

Name the image
Select the format of the image
Click Convert to Image

This operation will entail a series of status changes on the source volume.

Once the conversion is complete you may want to modify the resulting image further. E.g. if you need additional metadata or want to modify any properties.

Configure CLI

Usage

openstack image create --volume <volume> [--force]
                        [--protected | --unprotected]
                        [--public | --private]
                        [--property <key=value>]
                        [--tag <tag>]
                        <image-name>

<volume>: Volume to be used for conversion
--force: Performs the conversion regardless of the state of the source volume
--protected | --unprotected: Protects / Unprotects image from deletion
--public | --private: Controls whether image will be visible to the public or not
<key=value>: Sets a property on the image; Can be repeated
<tag>: Sets a tag on the image; Can be repeated
<image-name>: Identifier (name only) of image to be uploaded

OpenStack Terraform Provider

Example

View and modify an Image

UICLITerraform

You can access the details page of an image by

Clicking the name of an image on the image list.
Following a link to the image from where it is in use. E.g. on a servers storage details.

The image details show you all properties of an image and provide you with lists of

Servers created from the image
Volumes created from the image

OpenStack Terraform Provider

Example

Deleting an Image

Restrictions apply

You can only delete images that you own. The images provided by SysEleven can not be deleted.
An image has to be in the state AVAILABLE in order to be deletable.

UICLITerraform

Images can be deleted

From the list of images using the option at the end of each entry
From images detail page sing the Delete button in the titlebar

The option to delete will only be displayed for images that you own and are in a valid state.

Configure CLI

Usage

    openstack image delete <image>

<image>: Identifier of image to delete
