Stack Grafana deployed on AWS ECS -Part 1 - Create a Cluster

This post is part of a series about the stack Grafana deployed on AWS ECS. This project is a simple MVP.

In part 1, we will set up our cluster ECS and LoadBalance.

AWS ECS: is a container orchestration that helps us to deploy, manage, and scale applications.

Pre-Requirements

• Knowledge with Terraform
• AWS Account
  • 2 subnets publics, with tag: tier = public
  • 2 subnets private, with tag: tier = private

AWS VPC

We need the following structure for AWS VPC. We'll get ID the subnets privates with the Terraform DataSource.

Remember the add tag tier = private for private subnets.

Remember the add tag tier = public for public subnets.

ECS Cluster Type

Currently, there are three types of the ECS cluster. Cluster EC2 instance, serverless Fargate, and on-primeses VM.

Consult the AWS documentations for more details. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-configuration.html

We'll use the ECS EC2 cluster for this MVP.

Create ECS Cluster

You can use this Terraform module to create cluster ECS.

• https://github.com/EzzioMoreira/aws-terraform-module/releases/tag/v0.0.1-ecs-cluster-alb

Below an example how to use this module. That will provide a cluster ECS type of EC2, and Application LoadBalance.

module "ecs_cluster" {

  source = "https://github.com/EzzioMoreira/aws-terraform-module//modules/ecs-cluster?ref=v0.0.1-ecs-cluster-alb"

  min_size      = 1

  max_size      = 2

  desired_size  = 1
