placer - a simpler deployment
deployment back to the basics

If you have no config, just start off by the example in the repo/placer.yaml.
In case you are wondering, public/private key auth is the only way.
We don't support manual solutions. This tool is thought for automated use.

Usage: placer [options]
BANNER

  opts.banner = banner

  params[:log] = true
  opts.on('-q', '--[no-]log', 'toggle logging') do |val|
    params[:log] = val
  end

  params[:config_path] = 'placer.rb'
  opts.on('-c', '--config FILE', 'path to config FILE to use default: ' << params[:config_path]) do |file|
    params[:config_path] = file
  end

  params[:debug] = false
  opts.on('--debug', 'enable debugging') do
    params[:debug] = true
  end

  opts.on_tail('-h', '--help', 'shows this message') do
    puts opts
    exit
  end
