Description

Support for daemon services (1 task per ECS instance) was just added to ECS as a schedulingStrategy attribute when creating a service (api docs). Valid values are:

• REPLICA: this is the strategy that all ECS tasks used to be
• DAEMON: one task per ECS instance

It would be great to be able to create services of this type with terraform.

New or Affected Resource(s)

• aws_ecs_service

Potential Terraform Configuration

Note: I'm not sure if the scheduling_strategy values should be lowercase like most terraform configs or UPPERCASE to match the AWS API values.

resource "aws_ecs_service" "datadog" {
  name                = "datadog"
  cluster             = "${aws_ecs_cluster.foo.id}"
  task_definition     = "${aws_ecs_task_definition.datadog.arn}"
  iam_role            = "${aws_iam_role.foo.arn}"
  scheduling_strategy = "daemon"
}
