Versioning

This project follows semantic versioning <http://semver.org/>__.

In the context of semantic versioning, consider the role contract to be defined by the role variables.

Changes that require user intervention will increase the major version. This includes changing the default value of a role variable.
Changes that do not require user intervention, but add backwards-compatible features, will increase the minor version.
Bug fixes will increase the patch version.

Refer to the change log <CHANGELOG.rst>__ for upcoming changes.

The following variable defaults are defined in defaults/main.yml.

minecraft_version Minecraft version to install (default: latest)

Examples:

.. code:: yaml

Hooks and run stages

ansible-minecraft organizes execution into a number of run stages:

setup

install prerequisites (e.g., Java)
create Minecraft user and group

download

fetch the latest version of from the launcher API
download Minecraft

install

symlink version to minecraft_server.jar
agree to EULA

acl

configure server ACLs (whitelist, banned players, etc.)

configure

set server.properties

start

(re)start server

You can execute custom tasks before or after specific stages. Simply specify a task include file <https://docs.ansible.com/ansible/playbooks_roles.html#task-include-files-and-encouraging-reuse>__ using the relevant role variable:

.. code:: yaml

- hosts: minecraft
  roles:
    - role: devops-coop.minecraft
      minecraft_hook_before_start: "{{ playbook_dir }}/download-world-from-s3.yml"

The available hooks are:

minecraft_hook_before_setup run before setup tasks

minecraft_hook_after_setup run after setup tasks

minecraft_hook_before_download run before download tasks

minecraft_hook_after_download run after download tasks

minecraft_hook_before_install run before install tasks

minecraft_hook_after_install run after install tasks

minecraft_hook_before_start run before start tasks

minecraft_hook_after_start run after start tasks

Example

.. code:: yaml

- hosts: minecraft
  roles:
     - { role: devops-coop.minecraft, minecraft_whitelist: ["jeb_", "dinnerbone"]}

Contributing

The best way to contribute is to use this role to deploy your own Minecraft server! We really appreciate bug reports from the wild.

If you'd like to help with the project itself, here are some other ways you can contribute:

Add support for additional servers like Cuberite <https://cuberite.org/>__.
Write integration tests for Minecraft- or Spigot-specific configuration.
Share useful hooks.

Testing


Testing can be done using the provided Vagrantfile or by installing `Docker <https://docs.docker.com/engine/installation/>`__ and `Docker Compose <https://docs.docker.com/compose/>`__ locally.

Testing with Vagrant
"""""""""""""""""""""
This role includes a Vagrantfile used with a Docker-based test harness that approximates the Travis CI setup for integration testing. Using Vagrant allows all contributors to test on the same platform and avoid false test failures due to untested or incompatible docker versions.

1. Install `Vagrant <https://www.vagrantup.com/>`__ and `VirtualBox <https://www.virtualbox.org/>`__.

2. Run ``vagrant up`` from the same directory as the Vagrantfile in this repository.

3. SSH into the VM with: ``vagrant ssh``

4. Run tests with ``make``.

   ::

       make -C /vagrant xenial64 test

Integration tests use **systemd** by default. Set ``PROCESS_CONTROL`` to change this:

::

    make -C /vagrant trusty64 test PROCESS_CONTROL=supervisor

See ``make help`` for more information including a full list of available targets.

Testing with Docker and Docker Compose locally
""""""""""""""""""""""""""""""""""""""""""""""""
Alternatively, you can install `Docker <https://docs.docker.com/engine/installation/>`__ and `Docker Compose <https://docs.docker.com/compose/>`__ to run these tests locally on your machine.

1. Install `Docker <https://docs.docker.com/engine/installation/>`__ and `Docker Compose <https://docs.docker.com/compose/>`__.

2. Run tests with ``make``.

   ::

       make jessie64 test

Integration tests use **systemd** by default. Set ``PROCESS_CONTROL`` to change this:

::

    make trusty64 test PROCESS_CONTROL=supervisor
