ECS FARGATE

Description

This is Minimal ECS Fargate Service Module. These types of resources are supported:

Type

Load Balancer

type = lb is create target group and connect to ecs_service.

aws_lb_target_group

Private Service Discovery

type = sd is create private service discovery and connect to ecs_service.

aws_service_discovery_service

Nothing

type = no is not create more resources.

Auto Scalling

is_mem_scale = true or is_cpu_scale = true

Usage

module "fargate" {
  source              = "grandcolline/ecs-fargate/aws"
  version             = "1.2.0"
  service_name        = "FargateTestService"
  cluster_name        = aws_ecs_cluster.main.name
  task_definition_arn = aws_ecs_task_definition.main.arn
  container_name      = "ecs_demo_app"
  assign_public_ip    = true
  type                = "lb"
  service_subnets     = ["${var.service_subnet_id}"]
  lb_dns              = aws_alb.main.dns_name
}
