# 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

DOCKER_MY_NETWORK=caddy_net

# Reverse proxy

No need.<br>
There is no website managment. There is no accessing it through port 80 or 443.<br>
Just clients connecting through port 25565 and that does not go through reverse proxy.<br>
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?<br>
You want one server but you want people to be able to play creative or surival?<br>
Well you need `multiverse core`.<br>
How do the people move between these worlds?<br>
Well you need `multiverse portals` to be able to create a *lobby* world.<br>
Should they be able to bring stuff from one world to another? No?<br>
Well you need `multiverse inventory`.<br>
Should they spawn in lobby on connecting,
but also remember the position in the worlds when entering portals?<br>
Well you need the rest of that shit, `EssentialsX` and `EssentialsX Spawn`.<br>

**Plugins installation** - place the downloaded jar files in to 
  `~/docker/minecraft/minecraft-data/plugins`<br>
restart the server

check if the plugins are loaded using command `plugins`

How to setup the worlds

# 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`
