+# Minecraft server in docker
+
+###### guide-by-example
+
+![logo](https://i.imgur.com/GYq1N1l.png)
+
+# Purpose & Overview
+
+Open world building and surviving game.
+
+* [Official site](https://www.minecraft.net/en-us)
+* [Github](https://github.com/itzg/docker-minecraft-server)
+
+Minecraft is written in Java.
+
+[Purpur](https://purpurmc.org/docs/) version of the server
+is used in this setup along with few plugings,
+which allow to host multiple worlds on the same server.
+
+# Files and directory structure
+
+```
+/home/
+└── ~/
+    └── docker/
+        └── minecraft/
+            ├── minecraft-data/
+            ├── .env
+            └── docker-compose.yml
+```
+
+* `minecraft-data/` - a directory where bookstack will store its web app data
+* `.env` - a file containing environment variables for docker compose
+* `docker-compose.yml` - a docker compose file, telling docker how to run the containers
+
+You only need to provide the files.</br>
+The directory is created by docker compose on the first run.
+
+# docker-compose
+
+`docker-compose.yml`
+```yml
+services:
+  minecraft:
+    image: itzg/minecraft-server
+    container_name: minecraft
+    hostname: minecraft
+    restart: unless-stopped
+    env_file: .env
+    tty: true
+    stdin_open: true
+    ports:
+      - 25565:25565
+    volumes:
+      - ./minecraft-data:/data
+```
+
+`.env`
+```bash
+# GENERAL

+
+# Reverse proxy
+
+No need. There is no website managment.
+There is no accessing it through port 80 or 443.
+Just clients connecting through port 25565
+and that does not go through reverse proxy.
+But you **must forwarded 25565** on your firewall to your docker host.
+
+# Plugins
+
+This setup is written in august 2022<br>
+1.19.2 is the latest build
+
+* [multiverse core](https://dev.bukkit.org/projects/multiverse-core)
+* [multiverse portals](https://dev.bukkit.org/projects/multiverse-portals)
+* [multiverse inventory](https://dev.bukkit.org/projects/multiverse-inventories)
+* [EssentialsX](https://essentialsx.net/downloads.html)
+* [EssentialsX Spawn](https://essentialsx.net/downloads.html)
+
+Why the mods and what purpose?<br>
+You wanna one server but you want people to be able to play creative or surival>
+Well you need multiverse core.<br>
+How do the people move between these worlds?<br>
+Well you need multiverse portals and have "lobby world".<br>
+Can they bring stuff from one world to another? No?<br>
+Well you need multiverse inventory.<br>
+Do you want them to spawn in lobby on connecting,
+but remember also the position in the worlds when entering their portals?<br>
+Well you need the rest of that shit, EssentialsX and EssentialsX Spawn.<br>
+
+here go specific instructions when I do it again on fresh install
+
+
+
+
+
+# Update
+
+Manual image update:
+
+- `docker-compose pull`</br>
+- `docker-compose up -d`</br>
+- `docker image prune`
+
+# Backup and restore
+
+#### Backup
+
+Using [borg](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/borg_backup)
+that makes daily snapshot of the entire directory.
+  
+#### Restore
+
+* down the minecraft container `docker-compose down`</br>
+* delete the entire minecraft directory</br>
+* from the backup copy back the minecraft directory</br>
+* start the containers `docker-compose up -d`
