To create a task set

The following create-task-set example creates a task set in a service that uses an external deployment controller.

aws ecs create-task-set \
    --cluster MyCluster \
    --service MyService \
    --task-definition MyTaskDefinition:2 \
    --network-configuration "awsvpcConfiguration={subnets=[subnet-12344321],securityGroups=[sg-12344321]}"

Output:
