terraform-ecs-cluster

This repo contains a Terraform module to create an Amazon ECS Cluster.

  • Creates the cluster
  • Creates n-instances and attach them to the cluster
  • Create the required IAM roles, required for ECS Services.

Module usage:

  provider "aws" {
    access_key = "${var.access_key}"
    secret_key = "${var.secret_key}"
    region     = "us-east-1"
  }

module "ecs-cluster" {
    source                = "github.com/grey-systems/terraform-ecs-cluster.git?ref=master"
    environment           = "${var.environment}"
    name                  = "cluster-name"
    instance_keypair_name = "${var.keypair_name}"

    # use github.com/grey-systems/terraform-multitier-vpc to create the VPC and the subnetsOB
    vpc_subnet_ids        = ["${split(",", module.vpc_network.private_subnets_ids)}"]
    instances             = ["${var.ecs_instances}"]
}

Inputs

Name Description Type Default Required
allowed_subnets List of subnets that can access (all traffic) the ecs cluster instances. Intended for VPN/HQ/Devops networks to troubleshoot/testing the cluster directly list <list> no
environment Environment name. Used to name resources, so that you can use this same module for several environments. All resources will be named as {name}-{environment} string - yes
instance_keypair_name keypair name for the cluster node's instances string - yes
instances * List of instances defined by its type. * The default value will create 2x t2.small instances + 1x t2.medium instance list <list> no
name Name of the ecs cluster string - yes
vpc_subnet_ids List of vpc subnets to spare the different nodes of the cluster list - yes

Outputs

Name Description
ecs_service_role_arn Arn of the service role created for this cluster, required for ECS services
