Using Amazon EC2 launch templates with AWS PCS

In Amazon EC2, a launch template can store a set of preferences so that you don't have to specify them individually when you launch instances. AWS PCS incorporates launch templates as a flexible way to configure compute node groups. When you create a node group, you provide a launch template. AWS PCS creates a derived launch template from it that includes transformations to help ensure it works with the service.

Understanding what the options and considerations are when writing a custom launch template can help you write one for use with AWS PCS. For more information on launch templates, see Launching an Instance from a Launch an instance from a launch template in the Amazon EC2 User Guide.
