Instance Method Details

#derandomize(name) ⇒ Object

Strip the random string at end of the ec2 instance name

# File 'lib/forger/base.rb', line 33

def derandomize(name)
  if @options[:randomize]
    name.sub(/-(\w{3})$/,'') # strip the random part at the end
  else
    name
  end
end

#randomize(name) ⇒ Object

Appends a short random string at the end of the ec2 instance name. Later we will strip this same random string from the name. Very makes it convenient. We can just type:

forger create server --randomize

instead of:

forger create server-123 --profile server

# File 'lib/forger/base.rb', line 23

def randomize(name)
  if @options[:randomize]
    random = (0...3).map { (65 + rand(26)).chr }.join.downcase # Ex: jhx
    [name, random].join('-')
  else
    name
  end
end
