This product is subject to the "Pre-GA Offerings Terms" in the General Service Terms section of the Service Specific Terms. Pre-GA products are available "as is" and might have limited support. For more information, see the launch stage descriptions.

A Compute Engine instance template lets you describe a VM instance. You can then create groups of identical instances based on the template.

For more information, see the following:

• Compute Engine overview
• Instance template

Required configuration parameters

If your template includes a Compute Engine instance template component, you must configure the following parameters before you deploy.

Parameter name	Description and constraints	Background information
Project ID	The App Hub service project where you want to create the Compute Engine instance template.	Set up App Hub
Region	region	Regional and global instance templates

Optional configuration parameters

The following parameters are optional. To display advanced parameters, in the Configuration area, select Show advanced fields.
