Instance Method Details

#create(template, path, options = {}) ⇒ Object

Creates a monitrc file from a template, puts it on the server at the given path and sets file permissions to 0700.

  • template can be 'mongrel' or the name of a file or a string. 'mongrel' uses the standard mongrel templates provided with this package. See get_template below for a list of places searched for template files of your own.

def create(template, path, options = {})
  
  template = template.to_s
      
  options = add_default_options(options)

  if template == 'mongrel'
    config_data = mongrel_ports.collect {|port| render options.merge(:template => get_template(template), :port => port)}.join("\n\n")
  else
    config_data = render options.merge(:template => get_template(template))
  end
  put config_data, path, :mode => 0700

end

#get_template(template) ⇒ Object

Works out whether the given template is a file or string containing rhtml.

Checks:

  • current directory
  • monitrc_templates path (defaults to templates/monit)
  • capistrano-monit-tasks-templates dir where cappy-monit is installed (the standard templates are here)

If it can't find the file it assumes it's a one line string template and returns that
