Creates an instance launch template, or template for short. An instance launch template removes the need to configure a large number of parameters every time you create an instance.

Description

Instance launch templates contain preset configurations used to create instances, such as the instance region, image ID, instance type, security group ID, and public bandwidth settings. If the configuration of a certain parameter is not included in the template, that parameter must be specified manually during instance creation. After you create a template (CreateLaunchTemplate), its version number is set to 1 by default. You can create multiple versions (CreateLaunchTemplateVersion) based on this template. Version numbers start from 1 and increase sequentially. If you do not specify a template version number when creating an instance (RunInstances), the default version will be used.

When you call this operation, note that:

  • You can create up to 30 instance launch templates in each region. Each template can have up to 30 versions.
  • Most instance launch template parameters are optional. When you create a template, ECS does not verify the existence or validity of its parameter values. The validity of specified parameter values cannot be verified until you create instances with the template.
  • If you configure a certain parameter in an instance launch template, you cannot filter out this parameter when creating an instance (RunInstances). For example, if HostName=LocalHost is configured in the template, and the value of the HostName parameter is not specified in the RunInstances operation, the host name of the instance is still LocalHost. If you want to overwrite the HostName=LocalHost configuration, you can configure RunInstances or other parameters in the HostName=MyHost operation.

Debugging

You can use API Explorer to perform debugging. API Explorer allows you to perform various operations to simplify API usage. For example, you can retrieve APIs, call APIs, and dynamically generate SDK example code.
