lsyncd Cookbook

The lsyncd cookbook installs lsyncd, creates a basic config, and starts the
service. Additionally, it exposes the lsyncd_target resource to easily add sync
configs.

Through some ugly Lua hackery, the main config, /etc/lsyncd/lsyncd.conf.lua,
is setup such that it will include all sync configs in /etc/lsyncd/conf.d/.
The lsyncd_target resource pretty much just creates the configs in
/etc/lsyncd/conf.d/.

The basis for this cookbook came from
bflad's lsyncd cookbook.

Requirements

• Chef 11 or greater

Tested on:

• Debian 7.x (Wheezy)
• Ubuntu 12.04
• Ubuntu 14.04
• CentOS 6.5
• CentOS 7.0

Resources/Providers

lsyncd_target

Actions

• :create - creates a sync config
• :delete - deletes the sync config

Parameters

• mode - lsyncd sync mode. Defaults to rsync
• source - source directory. Required
• target - target directory to sync files to. Required
• user - User name to use when syncing content. Optional, will assume root if a user name is not provided.
• host - IP or hostname of remote host. Required for remote syncing with the rsync or rsyncssh modes.
• rsync_opts - list of rsync options
• exclude - list of exclusions
• exclude_from - path to file containing exclusions

Example

Sync a directory to another local directory:

include_recipe 'lsyncd'

lsyncd_target 'foo' do
  source '/tmp/foo'
  target '/tmp/bar'
  notifies :restart, 'service[lsyncd]', :delayed
end

You can also do remote rsync by specifying rsync or rsyncssh for the mode:

include_recipe 'lsyncd'

lsyncd_target 'foo' do
  host 'test'
  source '/tmp/foo'
  target '/tmp/bar'
  notifies :restart, 'service[lsyncd]', :delayed
end

Recipes

default.rb

Installs lsyncd, creates /etc/lsyncd/conf.d, sets up base config, and starts
lsyncd service. Note that the service will not actually start until you have a sync config in place.

Attributes

default[:lsyncd][:conf_d] = '/etc/lsyncd/conf.d'
default[:lsyncd][:log_file] = '/var/log/lsyncd.log'
default[:lsyncd][:status_file] = '/var/log/lsyncd-status.log'
default[:lsyncd][:interval] = 20

Testing

This cookbook includes chefspec unit tests and integration tests via test-kitchen and serverspec.
There is a test cookbook to exercise the lsync_target LWRP included.

I've included a custom matcher for chefspec. The methods available are:

• create_lsyncd_target
• delete_lsyncd_target

There is also an lsyncd_target chef_runner method, so you can do things like:

resource = chef_run.lsyncd_target('test1')
expect(resource).to notify('service[lsyncd]').to(:restart).delayed
