momeek/web-deployment-with-terraform

This is a Terraform project that sets up a minimal web server deployment on Amazon Web Services. Terraform is an infrastructure-as-code tool that lets you define cloud resources in configuration files and provision them automatically. The repository is written in HCL (HashiCorp Configuration Language), Terraform's native format. The deployment creates an Apache web server on an EC2 instance (AWS's virtual machine service), places it behind an Application Load Balancer (a service that distributes incoming traffic), and stores the Terraform state file in an S3 storage bucket. Traffic flows from the internet to the load balancer on port 80, then from the load balancer to the EC2 instance. Security groups restrict direct internet access: only the load balancer can reach the server on port 80, and port 22 is open for SSH provisioning. After the EC2 instance starts, Terraform connects via SSH to run a bootstrap script called myweb.sh that installs Apache, downloads the Infinite Loop HTML template from Tooplate, and starts the web server. The instance runs Amazon Linux 2 on a t3.micro machine in the us-east-1a region, using AWS's default VPC. A notable part of the README is a debugging account. The author spent time troubleshooting an SSH authentication error, checking key files, security group rules, AMI usernames, and public IP assignment, before discovering the fix was simply saving the editor file with Ctrl+S before running terraform apply. The connection block had been written but not saved, so Terraform was reading the old version. The README includes this story alongside a reference table of other legitimate SSH auth fixes for this setup.
