Elastic Compute Service:CreateLaunchTemplate

Last Updated:Sep 29, 2024

Creates a launch template. When you call this operation, you can specify parameters, such as TemplateTag, LaunchTemplateName, and ImageId, in the request. A launch template eliminates the need to configure a large number of parameters every time you create an Elastic Compute Service (ECS) instance.

Operation description

After you create a launch template by calling the CreateLaunchTemplate operation, a default version that has a version number of 1 is automatically generated for the launch template. You can call the CreateLaunchTemplateVersion operation to create additional versions for the launch template. Version numbers start from 1 and increment by 1. If you specify a launch template but do not specify a launch template version number when you call the RunInstances operation to create instances, the default version of the launch template is used.

Launch templates contain preset configurations that are used to create instances, such as the region ID, image ID, instance type, security group ID, and public bandwidth settings. If a specific parameter is not included in a launch template, you need to manually specify the parameter when you use the launch template to create instances.

Take note of the following items:

  • You can retain up to 30 launch templates in each region in your Alibaba Cloud account. Each launch template can have up to 30 versions.
  • Most parameters in launch templates are optional. When you create a launch template, ECS does not verify the existence or validity of specified parameter values. The parameter values are verified only when you use the launch template to create instances.
  • If you configured a specific parameter in a launch template, you cannot filter out the parameter when you call the RunInstances operation to create instances from the launch template. For example, if you set HostName to LocalHost in a launch template but do not specify HostName when you call the RunInstances operation to create instances from the launch template, the hostname of the created instances is LocalHost. If you want to overwrite LocalHost, which is the value of HostName in the launch template, you can set HostName to MyHost or a different value when you call the RunInstances operation.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
