Terraform AWS EC2 + Docker Deployment

This repository contains a Terraform project that provisions an AWS EC2 instance, sets up Docker, and automatically deploys a Spring Boot application in a container.

📌 Features

• Security Group: Allows HTTP (port 80) and SSH (port 22) access.
• SSH Key: Imports a local public SSH key for secure instance access.
• EC2 Instance:
  • Deploys an t2.nano EC2 instance with a predefined AMI.
  • Runs a startup script (user_data.sh) to install and configure Docker.
  • Pulls and runs a Docker container from Docker Hub.
• Dockerfile:
  • Uses openjdk:21 as the base image.
  • Copies the Spring Boot JAR into the container.
  • Exposes port 8080.
  • Defines the entry command to run the Java application.
