# supply_drop
supply_drop is a capistrano plugin to facitiate provisioning servers with puppet, without using the puppet server. It works by simply rsyncing your puppet configuration files to your servers and running puppet apply. It strives to allow you to write idiomatic puppet scripts while being as lightweight as possible.
[](http://travis-ci.org/pitluga/supply_drop)
### Installation
gem install supply_drop
or with Bundler
gem 'supply_drop'
then at the top of your deploy.rb
require 'rubygems'
require 'supply_drop'
### Tasks
cap puppet:bootstrap:ubuntu
cap puppet:bootstrap:osx
cap puppet:bootstrap:redhat
This does a simple apt-get install of puppet on the target servers.
cap puppet:noop
This will show you a list of the pending changes to be applied server-by-server.
cap puppet:apply
Applies the pending changes to all the servers.
cap puppet:syntax_check
Locally syntax checks all the puppet files and erb templates. Requires you to have puppet installed locally.
cap puppet:remove_lock
Remove any stale lock files created by supply_drop when locking is used and something went wrong.
You can specify that one of your servers should not be puppeted by setting the :nopuppet flag to true, like so. It will then be skipped by all the above commands.
role :weird_thing, '33.33.33.33', :nopuppet => true
### Variables
There are several variables that can be overriden to change how supply_drop works:
set :puppet_source, '.'
defines the base directory containing your puppet configs that will be rsynced to the servers.
set :puppet_destination, '/tmp/supply_drop'
defines where on the server the puppet configuration files are synced to.
set :puppet_command, 'puppet apply'
allows you to override the puppet command that is run if puppet is not on the path.
set :puppet_lib, "#{puppet_destination}/modules"
the value of the PUPPETLIB environment variable, the location of your puppet modules.
set :puppet_parameters, 'puppet.pp'
the parameters that are passed to the puppet call.
set :puppet_excludes, %w(.git .svn)
these are patterns that are passed as rsync --exclude flags when pushing your puppet configs to the box.
set :puppet_parallel_rsync, true
determines whether the rsync commands for multiple servers are run in parallel threads or serially
set :puppet_parallel_rsync_pool_size, 10
sets the maximum number of rsync commands that are run concurrently
set :puppet_syntax_check, false
when true, will syntax check your puppet files and erb templates before rsyncing them to your servers. This is an
experimental feature and is quite slow at the moment.
set :puppet_stream_output, false
will write the incremental output from the hosts to the screen instead of waiting until complete and printing by host.
set :puppet_write_to_file, nil
a file to additionally write puppet output to, useful for large noops with small scrollbacks.
set :puppet_runner, nil
allows you to specify the user to execute the puppet command as. Like running sudo -u puppet args from the command line.
set :puppet_lock_file, '/tmp/puppet.lock'
sets a lockfile on each remote host to prevent multiple users from puppeting the same node simultaneously. Set to nil to disable locking. You can alternately temporarily disable locking by setting the NO_PUPPET_LOCKING environment variable to any value.
### Handling Legacy Puppet
Puppet deprecated the implicit invocation of apply [in the 2.6.x series](https://github.com/puppetlabs/puppet/commit/a23cfd869f90ae4456dded6e5a1c82719b128f01).
The default behavior of supply_drop includes `apply` keyword in its commands, but if you need compatibility with older versions of puppet, set the `puppet_command` variable to omit it.
You'll need to do this if you see errors like this:
Could not parse for environment production: Could not find file /home/.../supply_drop/apply.pp
### How to contribute
If you write anything complicated, write a test for it. Test that your changes work using vagrant. Send a pull request. Easy peezy.
