Delete all archives in an Amazon Glacier Vault

glacier = AWS::Glacier.new(

  end.last

  if !succeeded_inventory_job
    inventory = glacier.client.initiate_job({
      :account_id => '-',
      :vault_name => vault_id,
      :job_parameters => {
        :type => 'inventory-retrieval'
      }
    })
    puts "Initiated Inventory Download... waiting 30 minutes"
    sleep 1800
  end
end while !succeeded_inventory_job

archives = JSON.parse(glacier.client.get_job_output(
  :account_id => '-',
  :vault_name => vault_id,
  :job_id => succeeded_inventory_job[:job_id]
).body)['ArchiveList']

puts "We have #{archives.length} archives to delete."

archives.each_with_index do |a, i|
  glacier.client.delete_archive(
    :account_id => '-',
    :vault_name => vault_id,
    :archive_id => a['ArchiveId']
  )
  puts "[OK] #{i}/#{archives.length}"
end

Also, does vault_id in line 11 refer to VaultARN. I could find no reference to vault_ID anywhere in the console or the documentation: http://docs.aws.amazon.com/amazonglacier/latest/dev/api-vault-get.html
