Terraform Plan to Create Auto Scaling Group

This plan will create the following resources:

Launch Template with EC2 instances prepared to install Kubernetes with kubeadm
Auto Scaling group to deploy as many instances as your heart desires

Instructions

Edit local.tf with your environment's information.
- Optionally, edit user_data.sh if you wish to alter the startup script.
Run terraform init and terraform validate to ensure the code is loaded properly.
Run terraform plan to see the results of a plan against your environment.
When satisfied, run terraform apply to apply the plan and construct the Launch Template and Auto Scaling group.
If more/less nodes are needed:
- Edit local.tf and modify the node-count value to the desired amount.
- Re-run terraform apply and the Auto Scaling group will create/destroy nodes to reach the new value.
When done, use terraform destroy to remove all resources and terminate potential billing.
