You can create a launch template using the following methods:
-
Create a launch template in the ECS console if you want to create launch templates first, and then create instances using a specific launch template in one click.
-
Create a launch template on the ECS buy page to create an instance and save its configuration information as a launch template.
Note
- Each account can create a maximum of 30 launch templates per region.
- All parameters are optional when you create a template using the ECS console. However, if the template that you want to use to create an instance does not have all required parameters (such as an image), then you must specify the required parameters at instance creation.
- A template cannot be modified after it is created.
