[Minetest](http://www.minetest.net/) \(server\) is a near-infinite-world block sandbox game and a game engine, inspired by InfiniMiner, Minecraft, and the like.

## Supported Architectures

Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).

Simply pulling `linuxserver/minetest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

| Architecture | Tag |
| :---: | :--- |
| x86-64 | amd64-latest |
| arm64 | arm64v8-latest |
| armhf | arm32v7-latest |

## Usage

Here are some example snippets to help you get started creating a container from this image.

### docker

```text
docker create \
  --name=minetest \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e CLI_ARGS="--gameid minetest" `#optional` \
  -p 30000:30000/udp \
  -v <path to data>:/config/.minetest \
  --restart unless-stopped \
  linuxserver/minetest
```

### docker-compose

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2.1"
services:
  minetest:
    image: linuxserver/minetest
    container_name: minetest
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - CLI_ARGS="--gameid minetest" #optional
    volumes:
      - <path to data>:/config/.minetest
    ports:
      - 30000:30000/udp
    restart: unless-stopped
```

## Parameters

Docker images are configured using parameters passed at runtime \(such as those above\). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.

### Ports \(`-p`\)

| Parameter | Function |
| :---: | :--- |
| `30000/udp` | Port Minetest listens on. |

### Environment Variables \(`-e`\)

| Env | Function |
| :---: | :--- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `TZ=Europe/London` | Specify a timezone to use EG Europe/London. |
| `CLI_ARGS="--gameid minetest"` | Optionally specify any [CLI variables](https://wiki.minetest.net/Command_line) you want to launch the app with |

### Volume Mappings \(`-v`\)

| Volume | Function |
| :---: | :--- |
| `/config/.minetest` | Where minetest stores config files and maps etc. |

## Environment variables from files \(Docker secrets\)

You can set any environment variable from a file by using a special prepend `FILE__`.

As an example:

```text
-e FILE__PASSWORD=/run/secrets/mysecretpassword
```

Will set the environment variable `PASSWORD` based on the contents of the `/run/secrets/mysecretpassword` file.

## Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.

## User / Group Identifiers

When using volumes \(`-v` flags\), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:

```text
  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
```

## Application Setup

You can find the world maps, mods folder and config files in /config/.minetest.

Client and server must be the same version, please browse the tags here to pull the appropriate version for your server:

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image \(if any\) can be accessed via the dynamic badge above.
