aws	AWS: aws_ecs_service	docs-aws-resource-ecs-service	Provides an ECS service.

aws_ecs_service

-> Note: To prevent race condition during service deletion, make sure to set depends_on to related aws_iam_role_policy, otherwise policy may be destroyed too soon and ECS service will then stuck in DRAINING state.

Provides an ECS service - effectively a task that is expected to run until an error occures or user terminates it (typically a webserver or a database).

See ECS Services section in AWS developer guide.

Example Usage

resource "aws_ecs_service" "mongo" {
  name = "mongodb"
  cluster = "${aws_ecs_cluster.foo.id}"
  task_definition = "${aws_ecs_task_definition.mongo.arn}"
  desired_count = 3
  iam_role = "${aws_iam_role.foo.arn}"
  depends_on = ["aws_iam_role_policy.foo"]

  load_balancer {
    elb_name = "${aws_elb.foo.id}"
    container_name = "mongo"
    container_port = 8080
  }
}

Argument Reference

The following arguments are supported:

• name - (Required) The name of the service (up to 255 letters, numbers, hyphens, and underscores)
• task_definition - (Required) The family and revision (family:revision) or full ARN of the task definition that you want to run in your service.
• desired_count - (Required) The number of instances of the task definition to place and keep running
• cluster - (Optional) ARN of an ECS cluster
• iam_role - (Optional) IAM role that allows your Amazon ECS container agent to make calls to your load balancer on your behalf. This parameter is only required if you are using a load balancer with your service.
• deployment_maximum_percent - (Optional) The upper limit (as a percentage of the service's desiredCount) of the number of running tasks that can be running in a service during a deployment.
• deployment_minimum_healthy_percent - (Optional) The lower limit (as a percentage of the service's desiredCount) of the number of running tasks that must remain running and healthy in a service during a deployment.
• load_balancer - (Optional) A load balancer block. Load balancers documented below.

-> Note: As a result of AWS limitation a single load_balancer can be attached to the ECS service at most. See related docs.

Load balancers support the following:

• elb_name - (Required) The name of the load balancer.
• container_name - (Required) The name of the container to associate with the load balancer (as it appears in a container definition).
• container_port - (Required) The port on the container to associate with the load balancer.

Attributes Reference

The following attributes are exported:

• id - The Amazon Resource Name (ARN) that identifies the service
• name - The name of the service
• cluster - The Amazon Resource Name (ARN) of cluster which the service runs on
• iam_role - The ARN of IAM role used for ELB
• desired_count - The number of instances of the task definition
