+
+Minecraft Vanilla Server Java Edition on Docker
+
+[![Build Status](https://drone.pyas.de/api/badges/Games/Minecraft-Vanilla-Server/status.svg)](https://drone.pyas.de/Games/Minecraft-Vanilla-Server)
+
+This Repository is mirrored from my [Gitea instance](https://git.pyas.de/Games/Minecraft-Vanilla-Server).
+
+## Image
+This image is based on the official Java JDK 18 image running on an Alpine image.
+
+For the Image on Docker Hub see [here](https://hub.docker.com/r/kimdrechsel/minecraft-vanilla-server).
+
+## Run
+### Latest version
+
+`docker run -p 25565:25565 kimdrechsel/minecraft-vanilla-server:latest`
+
+### Specific version
+
+`docker run -p 25565:25565 kimdrechsel/minecraft-vanilla-server:1.18`
+
+## Server.jar
+The latest `server.jar` gets 
+1. stored to `/opt` in the docker image 
+2. and symlinked to `/app/server.jar` 
+
+## Volumes
+- `/app` contains server-related files
+- `/app/world` contains the world data
+
+## Automated image building for new Releases 
+New images with the corresponding version as it's tag are created automatically when a new Minecraft server version is released (Checks run every 30 minutes).
