Manage worker/minion counts in an atomic fashion.

Usage

require 'gru'
require 'redis'
require 'logger'

client = Redis.new

class Gru::Adapters::RedisAdapter
  def hostname
    @hostname ||= ARGV[0]
  end
end

settings = {
  host_maximums: { 'test_worker' => 5 },
  cluster_maximums: { 'test_worker' => 10 },
  rebalance_flag: true
}

manager = Gru.create(settings)
logger = Logger.new(STDOUT)

loop do
  logger.info("STATE: #{manager.adjust_workers.inspect}")
  sleep(1)
