To create a MultiCloud image you will first need to provide a nickname and description. The next step is to manually select images for each cloud (AWS region) that you want to the MultiCloud Image to support under the Clouds tab.

A MultiCloud Image is a RightScale component that functions as a map or pointer to machine images in specific clouds. Each ServerTemplate must reference a single MultiCloud Image that defines which image should be used when a server is launched in a particular cloud. When you add a server to a deployment, the ServerTemplate's MultiCloud Image will determine for which cloud you will be allowed to create a server. For example, if a ServerTemplate is using a MultiCloud Image that only has references to images in the 'US-East' and 'US-West' regions, you will not be able to use that ServerTemplate to create a server in the 'EU' region. Based on the cloud that is selected, the server will inherit the appropriate image for that region (e.g. RightImage CentOS5.2i386_v4.2.4) based on what's defined by the MultiCloud Image. Once a server has been added, it will inherit the image that is specified for that region by the MultiCloud Image. Later, you can manually edit the server's configuration and select a different image.

Action Buttons

  • Clone - Clone the MultiCloud Image.
  • Commit - Commit the HEAD MultiCloud Image to create a static revision.
  • Delete - Permanently delete the MultiCloud Image and all of its previous revisions. You can only delete a MultiCloud Image if none of its committed revisions or HEAD version are being referenced by a ServerTemplate. The Delete button will only be displayed when viewing the HEAD version of the MCI.
  • Diff - Perform a diff between the currently viewed MCI version and either a different revision of the same MCI or of a completely different MCI. The resulting output window displays the two user specified templates in parallel, color coding all added (green), removed (red) and modified (blue) attributes.
  • Merge - After performing a diff, you may want to merge the changes between the MCIs together.
  • Publish to MultiCloud Marketplace - Publish the selected revision or HEAD version to the MultiCloud Marketplace. Once a component has been published to the MultiCloud Marketplace, it can be shared with other RightScale accounts via Account Groups.

Revisions tab

The Revisions tab shows the history of all committed revisions of a MultiCloud object. Select a particular revision to view. A revision is snapshot of a MultiCloud object's configuration at a particular time whereas the HEAD version is the working copy and only editable version of the MultiCloud object. New revisions are created using the 'Commit' action button when viewing the HEAD version.

Clouds tab

The Clouds tab lists all of the clouds supported by the MultiCloud Image. If you are creating a MultiCloud Image for the first time, you will need to specify at least one image for a cloud to make the MultiCloud Image functional. Add additional images for clouds as needed.

  • Instance type - The type of instance that will be launched. Instance types will vary depending on the cloud. For example, AWS: m1.small, m1.large Rackspace: 256 server, 2GB server, etc.). NOTE: The selected machine image must use the appropriate architecture for the selected instance type. For example on AWS, use a 32-bit image for 'small' and 'medium' instance types and 64-bit images for 'large' and 'xlarge' instance types.
  • Image - Select the machine image that will be used to build and launch an instance. The image selector filters the list so that you can only select an image that's available in the selected cloud. When possible, we recommend using one of our published RightImages. Warning: If you select a non-RightImage, RightScale will not be able to provide any support for your instance.
  • Kernel Image (AWS) - The kernel that you want to use for your instance. (Optional)
  • Ramdisk Image (AWS) - The ramdisk that you want to use for your instance. (Optional)
  • User Data (AWS) - Data to be passed into the instances using the EC2 user launch data (limited to 16KB). This field is rarely used but can be useful during development to pass configuration values into the instance.

In order to launch a server in a private cloud, you need RightImages that are designed for use with private clouds. You can access the appropriate RightImages by contacting RightScale Sales. Please contact your RightScale Sales Account Manager for assistance. If you do not have a RightScale Account Manager, please contact the sales department at

Info tab tab

The Info tab displays general information about the MultiCloud object.

  • Description - A short description of the MultiCloud Image.
  • Publishing - The publishing status of the MultiCloud Image. Options to publish a private MultiCloud object will only be visible in RightScale accounts enabled for sharing.
  • Created at - Timestamp of when the object was created.
  • Updated at - Timestamp of when the object was last updated.
  • Updated by - Email of the user who last updated its configuration.
  • Tag(s) - A list of private tags. Tags can only be added to a HEAD version. Tags are preserved when an MCI is committed.

Xref tab tab

The Xref tab displays all of the ServerTemplates that are using the MultiCloud Image. Remember, the cross-reference data that is shown is based on the selected revision or HEAD version of the MultiCloud Image. You will not be able to delete a MultiCloud Image object if it is being used by one of your ServerTemplates. The Xref tab is a great way to determine where a MultiCloud Image is being used across your account.
