How to create one Application Load Balancer with internal network and 2 instances EC2 with Terraform

First let’s set up our provider:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/provider.tf

This is the backend states from terraform where is going to S3 Bucket:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/backend.tf

We creates a new VPC with no GateWay:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/vpc.tf

We have the configuration for the Application Load Balancer:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/alb.tf

We set the AMI that will update and launch configuration of the cluster:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/data.tf

We can see that the load balancer is open to the world on tcp/80 and tcp/443 and the ECS EC2 instances have ports 32768 to 65535 open from the load balancer. This is because when we select the container port to 0 in the task definition AWS will randomly assign a port from this range to the container:

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/security.tf

We have our variables file where I am using CentOS 7 AMI :

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/vars.tf

We add terraform.tfvars for access and secret key.

vmbs/Creating-1-ALB-internal-and-2-EC2-with-Terraform/blob/main/terraform.tfvars
