ECS Service Prefix list

An AWS Lambda for automatically tracking ecs service task ip's in a Prefix list across regions

Description

Security groups cannot reference a security group from another region.(doc). The goal of this module is to create a managed AWS Prefix List that is automatically populated with the tasks ip adresses of an ECS service across region. Security groups from another region can reference this list to allow ingress traffic from a specific ECS service.

How to use with Terraform

requested providers

tracker: AWS provider that wants to track the ecs service in another region tracked: AWS provider of the ecs service being tracked

Add the module to your Terraform project:

module "terraform_aws_lambda" {
  source       = "github.com/agendrix/ecs-service-prefix-list.git//terraform?ref=v1.0.0"

  ecs_cluster_arn = aws_ecs_cluster.cluster.arn
  ecs_service = aws_ecs_service.service.name

  providers = {
    tracker = aws.ca-central-1
    tracked = aws.eu-west-3
  } 
}
