terraform attempts to destroy AWS ECS cluster before Deleting ECS Service

[jaloren]

I am using the aws_cloudformation_stack resource to provision an aws Elastic Container Service cluster and one or more services in that cluster. I used terraform graph -type=plan-destroy to verify that I successfully set up a dependency relationship in terraform between the TF resource for creating the service and the TF resource for creating the ECS cluster.

According to graphviz, the service is a child node of the ecs cluster node. Given that, I am expecting TF to delete the service and then delete the cluster. However, this seems to happen out of order, which causes the delete of the ECS cluster to fail since you can't delete a cluster that has services in it.

Terraform Version

Terraform v0.11.8

Expected Behavior

Terraform successfully delete aws ECS cluster and its associated services.

Actual Behavior

Terraform successfully deleted the service in the ECS cluster but failed to delete the ECS cluster itself with the following error:

* aws_cloudformation_stack.ecs-cluster: DELETE_FAILED: ["The following resource(s) failed to delete: [ECSCluster]. " "The Cluster cannot be deleted while Services are active. (Service: AmazonECS; Status Code: 400; Error Code: ClusterContainsServicesException; Request ID: 7bcbeae4-70ab-11e8-bd0b-3d3254c7f7d3)"]
