taskDefinitionArn

The Amazon Resource Name (ARN) of a task definition to use to create the Express Gateway service. This allows you to manage your own task definition, giving you more control over the service configuration such as adding sidecar containers.

The task definition must have a container named Main with a single TCP port mapping that includes a container port and port name. The task definition must also have FARGATE compatibility.

If you provide a task definition ARN, you cannot also specify primaryContainer, executionRoleArn, taskRoleArn, cpu, or memory.
