Working with Instance Launch Templates

Last updated: 2022-05-17 10:28:41

    Overview

    This document describes how to create, manage, and use an instance launch template in the CVM console to quickly create an instance. Such a template stores the configuration information required for CVM instance creation (excluding the instance password) and improves the efficiency and user experience.

    Notes

    • After an instance launch template is created successfully, its configuration cannot be modified.
    • You can create one or multiple versions of an instance launch template and set different configuration information for each version. You can also specify the default version, whose configuration will be used when you use the template to create an instance.
