Create a Custom Terraform Module

Hey there, Gurus! Welcome to the lab! This lab will demonstrate how to create a custom module, and then call that module with a root module in your main configuration. This will allow you to share a piece of configuration with multiple infrastructure projects. We will first set up our child module, which will configure an EC2 instance. We will then add a module block that will call our child module in our main configuration. So let's get started creating a custom module!

Challenge

Create a Custom Module
1. In the terminal, once logged in to your instance, change to the Use_Modules directory.
2. In the Use_Modules directory, edit the modules/ec2/main.tf file and add in your ami and subnet_id from the resource_ids.txt file.
3. In the Use_Modules directory, edit the ec2.tf file and add the following:
```
module "ec2-module" {
  source = "./modules/ec2/"
}
```
4. Examine the outputs.tf configuration files in both the Use_Modules and Use_Modules/modules/ec2/ directories.
5. Initialize your working directory.
6. Deploy your resources.
Challenge

Confirm Your EC2 Instance Has Been Created
1. Check your outputs to confirm your instance was deployed.
2. Check the lab-provided AWS console or use the AWS CLI to confirm your EC2 instance was created.
