SimpleWorker

Distribute automation tasks on multiple machines.

Gem Version Build Status

Usage

Ruby must be setup on the remote host such that it is available in the user's login shell.

require 'simpleworker'

tasks = ['first', 'second', 'third']
redis = Redis.new

# create a remote worker
ssh_worker = SimpleWorker::SshWorker.new(
  :user    => 'jesg'
  :host    => 'localhost',
  :cmd     => 'ruby -s worker.rb',
  # rsync will wipe out existing files in ~/my_unused_dir
  :dirname => 'my_unused_dir')

# create a local worker
local_worker = SimpleWorker::LocalWorker.new("ruby", "worker.rb")

runner = SimpleWorker::Runner.new(redis, tasks,
  :namespace    => 'foobar',                    # redis key prefix
  :notify       => [local_worker, ssh_worker],  # listeners that implement AbstractListener
  :max_retries  => 1,                           # max times expired tasks will be retried
  :timeout      => 60,                          # timout in seconds if inactive
  :task_timeout => 14,                          # max time for a task before it expires
  :interval     => 2)                           # interval at which to pull redis event log for the job in seconds

runner.run

Next create a script to work on the automation tasks.

require 'simpleworker'

redis      = Redis.new
task_queue = SimpleWorker::TaskQueue.new(redis, 'my_hostname', ENV['JOBID'],
  :namespace => 'foobar')

task_queue.fire_start

task_queue.each_task do |task|
  task_queue.fire_log_message(task)
end

task_queue.fire_stop

Requirements

  • redis

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
