Which solution meets these requirements?

A company is migrating an application to Amazon Elastic Container Service (Amazon ECS). The company wants to consolidate log data in Amazon CloudWatch in the us-west-2 Region. No CloudWatch log groups currently exist for Amazon ECS.

“service my-service-name was unable to place a task because no container instance met all of its requirements.”

The ECS task definition includes the following container log configuration:

" logConfiguration " : {

" logDriver " : " awslogs " ,

" options " : {

" awslogs-create-group " : " true " ,

" awslogs-group " : " awslogs-mytask " ,

" awslogs-region " : " us-west-2 " ,

" awslogs-stream-prefix " : " awslogs-mytask " ,

" mode " : " non-blocking " ,

" max-buffer-size " : " 25m "
