Setting Up a Minecraft Server with Docker on AWS Linux Terminal

Here's how you can create a Minecraft server using Docker on an AWS Linux terminal:

Prerequisites:

• An AWS account with an EC2 instance running Amazon Linux 2 or similar.
• Basic knowledge of Linux commands and Docker.
• A Minecraft server jar file (download from the official website or a trusted source).

Steps:

Connect to your EC2 Instance: Use SSH to connect to your EC2 instance using its public IP address or a bastion host.

Install Docker:

• Run the following commands to update package lists and install Docker:

sudo yum update -y
sudo amazon-linux-extras install docker        

• Start the Docker service:

sudo service docker start        

• Verify Docker installation:

docker ps        

Create a Docker User and Group:

• Create a dedicated user and group for running Docker:

sudo useradd -r minecraft 
sudo groupadd -r minecraft        

• Add the ec2-user to the minecraft group:

sudo usermod -a -G minecraft ec2-user        

Create a Directory for the Minecraft Server:

• Create a directory for your server files:

mkdir minecraft-server
cd minecraft-server        

Download the Minecraft Server Jar File:

Download the desired Minecraft server jar file into the minecraft-server directory.

Create a docker-compose.yml file:

• Create a file named docker-compose.yml with the following content:

version: "3.8"

services:
  minecraft-server:
    image: minecraft:latest
    restart: unless-stopped
    environment:
      EULA: TRUE
      SERVER_NAME: "your-server-name"
      # Optional: Specify world name, difficulty, etc.
    ports:
      - "25565:25565"
    volumes:
      - ./world:/data
    user: minecraft:minecraft        

Replace "your-server-name" with your desired server name.Uncomment and customize any optional environment variables.

Start the Minecraft Server:

• Run the following command to start the server:

docker-compose up -d        

This will download the Minecraft image, create and run a container, and map port 25565 on your server to port 25565 on the container.

• Connect to your Minecraft Server: Use your EC2 instance's public IP address or domain name and port 25565 to connect to the server from your Minecraft client.

Additional Notes:

• You can customize the server configuration by editing the server.properties file within the container (mounted volume).
• Consider using persistent storage for the world directory (/data) to avoid losing data when restarting the container.
• Secure your server by setting strong passwords and limiting access to port 25565.

Remember to adjust these steps based on your specific needs and environment. Enjoy your Minecraft server!
