General Info On The How And Why

The FTB-Server installation is devided into three parts:

1. The user/group and its home-dir
2. The FTB-Pack main directory and each version
3. The files/directories that contain world data, backup, and config that are symlinked into each version-dir

An installed FTB-Server will have the following directory structure:

/usr/local//
                       \_ Server.A.B.C
                                     \_ installation_files/directories
                                     \_ server.properties
                                     \_ symliked files/directories from .Addon
                       \_ Server.D.E.F
                                     \_ installation_files/directories
                                     \_ server.properties
                                     \_ symliked files/directories from .Addon
                       \_ Server #symlink to current version_dir for informational purposes
                       \_ .Addon
                               \_ ops.json
                               \_ whitelist.json
                               \_ banned-ips.json
                               \_ banned-players.json
                               \_ world/
                               \_ backups/
                               \_ ...

/usr/local/etc/rc.d/ftbserver

The JSON-Files cannot be delivered easily as templates since they are updated through Minecraft.
So you will have to manage them yourself in a wrapping Cookbook (or similar - see Usage below) and put them into the .Addon-directory
yourself. The Cookbook will then symlink these files to the current Server-directory. The world- and backups-directories will only
be created and then symlinked. That way the current world and backups will be available with every version within the installed pack.
For every new pack-version a new directory will be created that is called Server.<version> by default. And then a symlink named Server
will be created that points to the currently active installation. This symlink is for informational purposes only since it serves
no technical purpose in this Cookbook.

Attributes

Addon Config

• node['ftb_server']['addon_config']['files'] - Array with the config files that will be symlinked to the current version's directory. Only files in that Array are symlinked.

Usage

Standalone

• Add ftb_server::default to your Nodes run list
• Add pack name and version to your role/environment. Role-Example:

 override_attributes({
   "ftb_server" => {
       "pack" => {
           "name" => "FTBInfinityLite110",
           "version" => "1.3.3"
       }
   }
 })

In a wrapper-cookbook with managed JSON-Files

• Put your JSON-Files into the files-directory of your wrapper cookbook (See 'Addon Config' above for the default files that are configured in the array. Override for different files, if you know better)
• Add the following to your wrapper Cookbooks default.rb

node['ftb_server']['addon_config']['files'].each do |file|
  cookbook_file ::File.join(node['ftb_server']['pack_addon_dir'], file) do
    source file
    owner node['ftb_server']['user']['name']
    group node['ftb_server']['user']['group']
    mode '644'
  end
end

include_recipe 'ftb_server::default'

• Add pack name and version to your role/environment. Role-Example:

   override_attributes({
     "ftb_server" => {
         "pack" => {
             "name" => "FTBInfinityLite110",
             "version" => "1.3.3"
         }
     }
   })
  

Recipes

ftb_server::default

Add this recipe to your run list and set the needed attributes to get going

ftb_server::install

Gets the pack going. Included in the Default-Recipe

ftb_server::auto_restart

Creates a cronjob that restarts the server periodically, if node['ftb_server']['auto_restart']['enable'] is true
