BitTorrent Sync

Build Status

Overview

The btsync module allows you to easily manage BitTorrent Sync instances with Puppet.

Pre-requirement

If you don't already have a btsync package repository, you can include btsync::repo class, that will configure yeasoft repository for Debian and Ubuntu:

include btsync::repo

Usage

Just include the btsync class:

include btsync

Launching an instances

Declare an instance:

btsync::instance { 'user':
  storage_path => '/home/user/.sync',
  webui        => {
    listen   => '0.0.0.0:8888',
    login    => 'admin',
    password => 'password',
  }
}

You can also do it in one step:

class { 'btsync':
  instances => {
    user => {
      storage_path => '/home/user/.sync',
      webui        => {
        listen   => '0.0.0.0:8888',
        login    => 'admin',
        password => 'password',
      }
    }
  }
}

You can also store you configuration in hiera:

---
btsync::instances:
  user:
    storage_path: /home/user/.sync
    webui:
      listen: 0.0.0.0:8888
      login: admin
      password: password

And simply include the btsync class if you have puppet 3+:

include btsync

Shared folders

You can also declare a shared folder:

btsync::shared_folder { 'MY_SECRET_1':
  instance => 'user',
  dir      => '/home/user/bittorrent/sync_test',
}

Or in in one step:

class { 'btsync':
  instances => {
    user => {
      storage_path => '/home/user/.sync',
      webui        => {
        listen   => '0.0.0.0:8888',
        login    => 'admin',
        password => 'password',
      },
      shared_folders => {
        'MY_SECRET_1' => {
          dir => '/home/user/bittorrent/sync_test',
        }
      }
    }
  }
}

And of course in hiera:

---
btsync::instances:
  user:
    storage_path: /home/user/.sync
    webui:
      listen: 0.0.0.0:8888
      login: admin
      password: password
    shared_folders:
      MY_SECRET_1:
        dir: /home/user/bittorrent/sync_test

Known hosts:

A Btsync::Known_host resource is automatically exported for the given secret key, and every Btsync::Known_host resources matching the given secret key are automatically realized.

You can also declare explicitely a known host resource for a given secret key:

btsync::known_host { '192.168.1.2:44444':
  secret   => 'MY_SECRET_1',
  instance => 'btsync',
}

Or in one step:

class { 'btsync':
  instances => {
    user => {
      storage_path => '/home/user/.sync',
      webui        => {
        listen   => '0.0.0.0:8888',
        login    => 'admin',
        password => 'password',
      },
      shared_folders => {
        'MY_SECRET_1' => {
          dir         => '/home/user/bittorrent/sync_test',
          known_hosts => ['192.168.1.2:44444'],
        }
      }
    }
  }
}

Or with hiera:

---
btsync::instances:
  user:
    storage_path: /home/user/.sync
    webui:
      listen: 0.0.0.0:8888
      login: admin
      password: password
    shared_folders:
      MY_SECRET_1:
        dir: /home/user/bittorrent/sync_test
        known_hosts: ['192.168.1.2:44444']

The define also supports composite namevars in order to easily specify the entry you want to manage. The format for composite namevars is:

<secret> on <host>

Example:

btsync::known_host { 'my known host':
  secret => 'MY_SECRET_1',
  host   => '192.168.1.2:44444',
}

equals to

btsync::known_host { 'MY_SECRET_1 on 192.168.1.2:44444': }

or with an array:

btsync::known_host { prefix(['192.168.1.2:44444'], 'MY_SECRET_1 on '): }

This example configures an instance like the sample configuration of BitTorrent Sync 1.1.48:

---
btsync::instances:
  user:
    device_name: My Sync Device
    listening_port: 0
    storage_path: /home/user/.sync
    check_for_updates: true
    use_upnp: true
    download_limit: 0
    upload_limit: 0
    webui:
      listen: 0.0.0.0:8888
      login: admin
      password: password
    shared_folders:
      MY_SECRET_1:
        dir: /home/user/bittorrent/sync_test
        use_relay_server: true
        use_tracker: true
        use_dht: true
        search_lan: true
        use_sync_trash: true
        known_hosts: ['192.168.1.2:44444']

Reference

Classes:

Resources:

###Class: btsync This class is used to install btsync.

####version The version of BitTorrent Sync to install/manage.

####enable Should the service be enabled during boot time?

####start Should the service be started by Puppet

####instances Hash of instances to run

###Class: btsync::config Configure btsync. You should not declare this class explicitely, it should be done by btsync class.

###Class: btsync::install Install btsync. You should not declare this class explicitely, it should be done by btsync class.

###Class: btsync::repo Configure yeasoft repository for Debian or Ubuntu.

###Class: btsync::service Manage btsync service. You should not declare this class explicitely, it should be done by btsync class.

###Resource: btsync::instance This resource is used to declare a btsync instance to run.

####user A uid for supplying the user under which the btsync daemon should run. Defaults to resource name.

####group A gid for supplying the group under which the btsync daemon should run. If omitted the daemon will run under the primary group of the user.

####umask The umask for the btsync damon. If omitted the default umask is used.

####conffile Override default configuration file. Defaults to /etc/btsync/$name.conf

####device_name Public name of the device. Defaults to $name.

####listening_port Port the daemon listen to. Defaults to 0 (random port).

####storage_path storage_path dir contains auxiliary app files if no storage_path field: .sync dir created in the directory where binary is located.

####pid_file Override location of pid file.

####check_for_updates Whether or not check for updates. Defaults to false.

####use_upnp Whether or not use UPnP for port mapping. Defaults to true.

####download_limit Download limit in kB/s. 0 means no limit. Defaults to 0.

####upload_limit Upload limit in kB/s. 0 means no limit. Defauls to 0.

####webui Hash containing web user interface configuration.

####webui['listen'] Address and port to listen to.

####webui['login'] Web ui login.

####webui['password'] Web ui password.

####webui['api_key'] Web ui API Key (Beta)

####shared_folders Hash containing shared folders resources.

####disk_low_priority Sets priority for the file operations on disc. If set to false, Sync will perform read and write file operations with the highest speed and priority which can result in degradation of performance for othe applications.

####folder_rescan_interval Sets a time interval in seconds for rescanning sync folders. This serves as an additional measure for detecting changes in file system.

####lan_encrypt_data If set to true, will use encryption in the local network.

####lan_use_tcp If set to true, Sync will use TCP instead of UDP in local network. Note: disabling encryption and using TCP in LAN can increase speed ofsync on low-end devices due to lower use of CPU.

####max_file_size_diff_for_patching Determines a size difference in MB between versions of one file for patching. When it is reached or exceeded, the file will be updated by downloading missing chunks of information (patches). Updates for a file with a smaller size difference will be downloaded as separate files.

####max_file_size_for_versioning Determines maximum file size in MB for creating file versions. When this size is exceeded, versions will not be created to save space on disk.

####rate_limit_local_peers Applies speed limits to the peers in local network. By default the limits are not applied in LAN.

####send_buf_size Amount of real memory that will be used for cached send operations. This value can be set in the range from 1 to 100 MB.

####recv_buf_size Amount of real memory that will be used for cached receive operations. This value can be set in the range from 1 to 100 MB.

####sync_max_time_diff Shows maximum allowed time in seconds difference between devices. If the difference exceeds this limit, the devices will not be synced as it may result in incorrect tracing of file changes.

####sync_trash_ttl Sets the number of days after reaching which files will be automatically deleted from the .SyncArchive folder.

###Resource: btsync::shared_folder This resource is used to declare a btsync shared folder for an instance.

####instance Name of the instance sharing this folder.

####dir Directory to share.

####secret Shared secret. Defaults to resource name.

####use_relay_server Whether or not use relay server when direct connection fails. Defaults to true.

####use_tracker Can be enabled to facilitate communication between peers.

####use_dht

####search_lan

####use_sync_trash Whether or not save all the files deleted on other clients to the hidden '.SyncArchive' within your destination folder. The files deleted on your computer are moved to system Trash (depending on OS preferences).

####known_hosts An array containing the ip:port or host:port of known clients. So if one of your devices has a static and accessible IP, peers can connect to it directly.

###Resource: btsync::known_host Add a known host to the list of known hosts of a shared folder.

####secret The secret of the shared folder.

####instance The instance to use. Defaults to the instance of the shared folder of the secret passed as parameter.

####host The host to add. Defaults to namevar.
