Configure a Compute Engine instance template in Application Design Center

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:

This document describes the parameters you can configure when using App Design Center to create a Compute Engine instance template.

Required configuration parameters

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