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.
