# Minecraft Docker Image # Minecraft Container Image
This Dockerfile sets up a Minecraft server based on the `debian-slim` image.
## Quick Start ## Quick Start
By running the following and building this image, you are agreeing to Assume a clean repository (i.e., without .env and plugins.json in the top
[Minecraft's EULA](https://www.minecraft.net/en-us/eula): directory), and Docker cache. You can use `make clean` to clear specific
default images and prune the unused build cache. However, you'll still need to
inspect all containers and images to ensure you've removed them all.
- `make clean` only removes certain images and prunes the builder cache.
### Steps
1. **Configure your build:**
```
make configure
```
This defaults to `make configure BUILD=basic`, but if you have directories
in `./scratch`, you can specify those build names here. Repository-included
builds are in`./builds`, but it's advised to copy `./builds/basic` or
whichever build configuration you are basing off and copy it into
`./scratch/X` to control your settings apart from the repository. This
separation allows you to manage your configurations independently and avoid
overwriting repository defaults.
2. **Build the PaperMC server:**
```
make paper
```
This builds the PaperMC server, which is likely what you want unless you
prefer a 100% vanilla server experience. PaperMC is recommended for its
performance benefits and support for Bukkit API server mods. Both
EssentialsX and WorldGuard suggest using Paper for better performance and
stability.
3. **(Optional) Install for testing:**
```
make install
```
This runs `docker compose up -d` and brings up a `minecraft-minecraft-1`
network/container compose stack using the `.env` and `plugins.json` in the
root of the repository. It includes settings for image overrides, the
`EULA` agreement, and a `DEBUG` option for the custom `entrypoint.sh`
script, Java options (defaulting to `-Xms1G -Xmx2G`), and the ability to
set any `server.properties` file entry using the `SETTINGS_` prefix in the
compose file. The purpose of `make install` is for testing only, and it is
advised not to rely on it for managing an actual server deployment. You
will likely want to add other settings not specified in the
`docker-compose.yml` and manage your own compose files.
## Additional Notes
### Image Management
All images are tagged with `localhost/minecraft`, etc. It's acceptable not to
override these default image names and just tag your own versions after
building the `localhost` images. The images will include git hash information
for extra traceability.
After using the quick start, you'll get something like this:
``` ```
echo "EULA=true" > .env $ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/minecraft 1.20.1-paper 814edda474c4 9 seconds ago 568MB
localhost/minecraft-jre latest 50350d8d3947 30 seconds ago 379MB
``` ```
Build the image using the Makefile: It is advisable to tag your own images and push them to a private container
repository, as you'll want to avoid pushing these images to a public DockerHub
repository due to the Minecraft EULA with typical proprietary software
non-redistribution rules.
``` ```
make build docker tag localhost/minecraft:1.20.1-paper example.org/minecraft:1.20.1-paper
docker push example.org/minecraft:1.20.1-paper
``` ```
Optionally, build _and_ run to test it: ## License

make install
```
Feel free to use `docker compose` directly to build and test:
```
docker compose build
docker compose up -d
docker logs -f minecraft-minecraft-1
```
