## Adding a server type

Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:

1. Copy an existing "start-deploy*" script, such as [start-deployFabric](https://github.com/itzg/docker-minecraft-server/blob/master/scripts/start-deployFabric) and rename it accordingly making sure to retain the "start-deploy" prefix
2. Modify the type-specific behavior between the "start-utils" preamble and the hand-off to `start-setupWorld` at the end of the script 
3. Develop and test the changes using the [iterative process described below](#iterative-script-development)
4. Add a case-entry to the `case "${TYPE^^}"` in [start-configuration](https://github.com/itzg/docker-minecraft-server/blob/master/scripts/start-configuration)
5. Add a section to the [docs](https://github.com/itzg/docker-minecraft-server/tree/master/docs). It is recommended to copy-modify an existing section to retain a similar wording and level of detail
6. [Submit a pull request](https://github.com/itzg/docker-minecraft-server/pulls)

## Iterative script development

The included `compose-dev.yml` will mount the local `scripts` code into the container and allow for iterative development. Replace `[-e key=value]` with any environment variables you wish to set for testing the modified scripts.

```shell
docker compose -f compose-dev.yml run --rm -it [-e key=value]  mc-dev
```

!!! tip

    To speed up the development cycle, it is recommended to set `SETUP_ONLY` to `true` as part of the run command above.

## Using development copy of tools

In the cloned repo, such as [`mc-image-helper`](https://github.com/itzg/mc-image-helper), install the distribution locally by running:

```shell
./gradlew installDist
```

The distribution will be installed in the project's `build/install/mc-image-helper`. Obtain the absolute path to that directory use in the next step.

Refer to the instructions above to mount any locally modified image scripts or build a local copy of the image using or with alternate `BASE_IMAGE`, as described above:

```shell
docker build -t itzg/minecraft-server .
```

Mount the local mc-image-helper distribution directory as a volume in the container at the path `/usr/share/mc-image-helper`, such as

```shell
docker run -it --rm \
  -v /path/to/mc-image-helper/build/install/mc-image-helper:/usr/share/mc-image-helper \
  -e EULA=true \
  itzg/minecraft-server
```

In a compose file, include the volume mount in the `volumes` section of the container definition:

```yaml
services:
  mc:
    # ... usual container definition
    volumes:
      - /path/to/mc-image-helper/build/install/mc-image-helper:/usr/share/mc-image-helper:ro
```

For Go base tools, run

```shell
goreleaser release --snapshot --clean
```

Clone [itzg/github-releases-proxy](https://github.com/itzg/github-releases-proxy) and run it according to the instructions shown there.

In the Docker build, configure the following 

```shell
--build-arg GITHUB_BASEURL=http://host.docker.internal:8080 \
--build-arg APPS_REV=1
```

and declare one or more version overrides, such as

```
--build-arg MC_HELPER_VERSION=1.8.1-SNAPSHOT
```

## Generating release notes

The following git command can be used to provide the bulk of release notes content:

```shell script
git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="* %s" 1.1.0..1.2.0
```
