User Data Scripts

The userdata.sh and userdata1.sh files should contain the initialization scripts for the EC2 instances.

Deployment

1. Initialize the Terraform project:

terraform init

2. Validate the configuration:

terraform validate

3. Plan the deployment:

terraform plan -var="cidr=<your-cidr-block>"

4. Apply the deployment:

terraform apply -var="cidr=<your-cidr-block>"

Outputs

After the deployment, the DNS name of the load balancer will be outputted. You can find it in the outputs.tf file.

Cleanup

To delete the created resources, apply the below command:

terraform destroy -var="cidr=<your-cidr-block>"
