PENDING CLEANUP

Module 8: Terraform Assignment - 4

Tasks To Be Performed:

1. Destroy the previous deployments
2. Create a VPC with the required components using Terraform
3. Deploy an EC2 instance inside the VPC

Step 1 §

Destroying infrastructure from Assignment 3 – Terraform

Step 2-3 §

In this configuration:

• A VPC is created with a specified CIDR block.
• A subnet is defined within the VPC.
• An Internet Gateway is attached to the VPC to allow communication with the internet.
• A route table with a default route to the Internet Gateway is created and associated with the subnet.
• A security group with basic rules for SSH access is defined and associated with the VPC.
• An EC2 instance is deployed within the created subnet and attached to the security group.

terraform apply

Just to test the instance i try to ssh into it
