This project sets up a Minecraft server on an Amazon EC2 instance using AWS CloudFormation.

The CloudFormation template in this project sets up the following resources:

• A VPC (Virtual Private Cloud) for hosting the Minecraft server.
• A public subnet within the VPC.
• An internet gateway attached to the VPC for internet access.
• A route table and a route that directs all traffic to the internet gateway.
• An IAM role and instance profile for allowing the EC2 instance to communicate with AWS Systems Manager.
• A security group that allows incoming TCP traffic on port 25565 for Minecraft.
• An Elastic IP address for the EC2 instance.
• An EC2 instance that runs the Minecraft server. The instance is of type t4g.small and uses the latest Amazon Linux AMI.

The template takes the following parameters:

• MinecraftServerUrl: The URL to download the Minecraft server jar file.
• JavaXmxValue: The maximum memory allocation pool for the JVM.
• JavaXmsValue: The initial memory allocation pool for the JVM.
• LatestAmiId: The ID of the latest Amazon Linux AMI.

The template outputs the following:

• MyEC2Instance: The ID of the EC2 instance running the Minecraft server.
• MyEIP: The Elastic IP address of the Minecraft server.

To use this template, navigate to the AWS CloudFormation console and create a new stack. Upload the template file and provide the necessary parameters. Once the stack creation is complete, you can connect to the Minecraft server using the outputted Elastic IP address.
