Introduction:
Minecraft is a popular sandbox video game, and with Docker, you can easily create and manage a Minecraft server. Docker allows you to encapsulate the server environment, making it easy to deploy and maintain. In this guide, we’ll show you how to set up a Minecraft server using Docker and configure its settings.

Step 1: Install Docker
Before proceeding, ensure you have Docker installed on your system. If you haven’t installed Docker yet, follow the official Docker installation instructions for your operating system.

Step 2: Pull the Minecraft Server Docker Image
To run the Minecraft server, pull the latest Minecraft Server Docker image from Docker Hub using the following command:

docker pull itzg/minecraft-server:latest

Step 3: Create and Start the Minecraft Server Container
Run the following command to create and start the Minecraft server container:

docker run -d -it --name minecraft -v minecraft_data:/data -p 25565:25565 -e EULA=TRUE -e MODE=creative -e MEMORY=2G -e tty=true --restart always itzg/minecraft-server:latest

Explanation of options used:

  • -d: Run the container in the background (detached mode).
  • -it: Allocate a pseudo-TTY and keep STDIN open, allowing you to interact with the server console.
  • --name minecraft: Assign the name “minecraft” to the container for easy management.
  • -v minecraft_data:/data: Create a Docker volume named “minecraft_data” and mount it to the /data directory inside the container. This volume allows you to persist Minecraft world data and configurations.
  • -p 25565:25565: Map port 25565 from the container to the host system. This is the default port for Minecraft servers.
  • -e EULA=TRUE: Accept the Minecraft End User License Agreement (EULA).
  • -e MODE=creative: Set the server mode to “creative.” You can change this to “survival” or other valid game modes.
  • -e MEMORY=2G: Set the allocated memory for the server to 2GB. Adjust this value based on your server’s requirements.
  • -e tty=true: Enable the TTY (Terminal) for interacting with the server console.
  • --restart always: Configure the container to automatically restart if it stops unexpectedly.

Step 4: Access the Minecraft Server Console
To access the Minecraft server console interactively, use the following command:

docker attach minecraft

This command will attach your current terminal to the running Minecraft server container, providing you with an interactive console to manage the server.

Step 5: Clean Up
If you want to stop and remove the Minecraft server container and the associated volume, use the following commands:

docker stop minecraft
docker rm minecraft
docker volume rm minecraft_data

Conclusion:
You’ve successfully set up a Minecraft server using Docker, allowing you to host and manage your Minecraft world easily. Docker’s portability and isolation make it a convenient choice for running a Minecraft server without interfering with your host system. Enjoy playing and exploring your Minecraft creations!

Happy mining!
