Amazon ECS task definition template
An empty task definition template is shown as follows. You can use this template to
create your task definition, which can then be pasted into the console JSON input area
or saved to a file and used with the AWS CLI --cli-input-json option. For
more information, see Amazon ECS task definition parameters for Fargate.

Fargate template
Important
For Fargate, you must include the operatingSystemFamily parameter with one of the
following values:
-
LINUX
-
WINDOWS_SERVER_2019_FULL -
WINDOWS_SERVER_2019_CORE -
WINDOWS_SERVER_2022_FULL -
WINDOWS_SERVER_2022_CORE

You can generate this task definition template using the following AWS CLI command.
aws ecs register-task-definition --generate-cli-skeleton
