About

A terraform file that creates a VPC and initialises a public subnet in it.

Installation

The build has been tested with Terraform v1.4.5.

Steps:

1. Install Terraform
2. Expose your AWS "access key id" and "secret access key" to the current terminal session with:

export AWS_ACCESS_KEY_ID=yourAccessKeyId
export AWS_SECRET_ACCESS_KEY=yourSecretAccessKey

3. Initialise Terraform with:

terraform init

4. Preview the changes that Terraform plans to make to your infrastructure with:

terraform plan

5. Apply the changes with:

terraform apply

6. Create a .pem key with the name main-key using the AWS Management Console > EC2 > Network & Security > Key Pairs. This key name is associated in the Terraform file while initialising the EC2 instance.
7. SSH to the server

ssh -i "main-key.pem" ubuntu@public.ip.goes.here

8. Destory the AWS infrastructure with:

terraform destroy

1. What is Internet Gateway?
2. Why did we define a custom routing table?
3. Why do we use elastic IPs?
