SSHKit::Chunky::Runner

Runs ssh commands in few chunks. It divides hosts into static number of chunks, you just need to specify how many chunks you need.

Installation

Add this line to your application's Gemfile:

gem 'sshkit-chunky-runner'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sshkit-chunky-runner

Usage

hosts = %w(
  1.example.com
  2.example.com
  3.example.com
  4.example.com
  5.example.com
  6.example.com
  7.example.com
  8.example.com
)
on hosts, in: :chunks, count: 3, wait: 5 do
  within '/opt/sites/example.com' do
    as :deploy  do
      with rails_env: :production do
        rake 'assets:precompile'
      end
    end
  end
end

This will divide all hosts into 3 groups.

First group will have 1.example.com, 2.example.com, 3.example.com, second group - 4.example.com, 5.example.com, 6.example.com, and the last one - 7.example.com, 8.example.com.

If you add more hosts, each group then will have more hosts. Number of groups remain the same.
