Class Method Details

.truncate_id(id, postfix = '') ⇒ Object

# File 'lib/jets/cfn/base.rb', line 70

def truncate_id(id, postfix = '')
  # Api Gateway resource name has a limit of 64 characters.
  # Yet it throws not found when ID is longer than 62 characters and I don't know why.
  # To keep it safe, let's stick to the 62 characters limit.
  if id.size + postfix.size > 62
    "#{id[0..(55 - postfix.size)]}#{Digest::MD5.hexdigest(id)[0..5]}#{postfix}"
  else
    "#{id}#{postfix}"
