Manage launch templates

A launch template stores the configuration of a series of launch settings. It allows you to quickly create KEC instances without repeatedly setting KEC parameters. A launch template contains all configuration information, such as the type and network settings of an instance, other than passwords.

Limits

• You can create up to 50 launch templates for each region within a single account.

• The elastic IP addresses in a launch template can only be automatically allocated.

Create a launch template

You can either create a launch template beforehand or save one when you are creating an instance.

Create a launch template beforehand
