You can request an image (a type of template for a virtual machine) of a running instance. This saves a complete copy of all changes and updates made to the instance since it was launched so it can be reused at any time. It also saves resources by launching the instance only when you need it.
You also can see the list of all image requests you have made.
You can add a script before requesting the image that executes after an instance using the image is launched and active.
PLEASE NOTE: Images will get created on the IU cloud by default, no matter which cloud they originated from. They will automatically be synced nightly to the TACC cloud.
The following directories are deleted as part of the imaging process:
Users are encouraged to test launch any image created to validate that it behaves as expected before suspending or removing their current active instance.
Creating an image on the SMALLEST possible size VM on which it will run will allow the image to be launched on VMs of the same size and larger.
For example, an image created on a Tiny size VM can be launched on a VM of any size; an image created on a Medium VM can only be launched on a Medium or larger size VM.
BEST PRACTICE: Update before Imaging
Users are encouraged to upgrade the operating system before imaging.
For CentOS based systems:
sudo yum update.
For Ubuntu based systems:
sudo apt-get update and then
sudo apt-get upgrade.
Can an image be exported?
Yes...and no. Currently an automated method for exporting images to run on other systems is not available but if you find that you do need to export an image to something other than IU Scholarworks contact firstname.lastname@example.org.
Image Request - Image Info
The information you provide on here will help others to discover this image.
Create or Update? (optional): The default is to create a new image, but if you are updating an image to a new revision, you can uncheck this box and it will be created as a new version of the same image. You can see examples of this with the Ubuntu 18.04 Featured image on Atmosphere. We recommend you update the image when possible.
New Image Name (required): Enter the name, up to 30 characters, to assign to the new image. Please DO NOT use the name of an existing featured image. Please be mindful of re-using the name of one of your own existing images.

Versioning is an important part of the imaging process. Use this information to track how your image changes over time. This information will also be helpful to others that wish to use your image.
New Version Name (required): Enter the new (unique) name or number of the image. Versioning helps users understand how your changes relate to the overall progress of the Application. Versions are alphanumeric (e.g. 2.0-stable, 2.1-beta, 2.2-testing). Limit the name to 30 characters and keep versioning consistent.
Change Log (required): Concisely describe what you've changed in this specific version. This description will help users understand how your application as changed over time.
