softlayer-api-ruby-client で Object Storage を利用する #softlayer
この記事は1年以上前に投稿されました。情報が古い可能性がありますので、ご注意ください。
Object Storage とは
SoftLayer のストレージにはさまざまな種類がありますが、本記事では Object Storage を取り扱います。
以前の記事 でも触れましたが、Object Storage とはデータをオブジェクトとして扱うアーキテクチャです。ファイルツリーでデータを扱うファイルシステムや、 セクタやトラックのブロックとしてデータを扱うブロックストレージとは異なります。Object Storage は比較的安価に大量の非構造化データを扱うことができるため、さまざまな用途への活用が進んでいます。
SoftLayer の Object Storage は OpenStack Swift をベースとしています。
softlayer-api-ruby-client で Object Storage を注文する
Object Storage も softlayer-api-ruby-client を用いて注文が可能です。SoftLayer_Product_Order::placeOrder を用いますが、やはりマジックナンバーが必要です。先の記事のプログラムで Object Storage の Package ID を調べてみました。
:
(中略)
:
{"firstOrderStepId"=>1,
"id"=>206,
"isActive"=>1,
"name"=>"Object Storage",
"unitSize"=>nil},
:
(中略)
:
Object Storage の Package ID は 206 とわかりました。
次に Object Storage の Price ID を確認しましょう。これも 先の記事のプログラムのように確認します。
Required Category "Cloud Storage" -- 74:
16984 -- Object Storage - Pay as you go
これで Object Storage を注文するために必要な ID が揃いました。
なお、SoftLayer の Object Storage は利用したぶんだけ課金される仕組みになっています。
softlayer-api-ruby-client で Object Storage の注文内容を検証する
Object Storage の注文内容は SoftLayer_Container_Product_Order データタイプで構成されています。次のような形になるでしょう。
product_order = {
'complexType' => 'SoftLayer_Container_Product_Order',
'quantity' => 1,
'packageId' => 206, # 206 is 'Object Storage' package ID
'useHourlyPricing' => false,
'prices' => [
{ 'id' => 16984 }, # "Object Storage - Pay as you go"
]
}
先の記事と同様に、SoftLayer_Product_Order::verifyOrder で注文内容を検証しましょう。
#!/usr/bin/ruby
require 'softlayer_api'
require 'pp'
#
# fill your SoftLayer API username and API key
#
api_username = ENV['SOFTLAYER_API_USERNAME'] || 'YOUR_SOFTLAYER_API_USERNAME'
api_key = ENV['SOFTLAYER_API_KEY'] || 'YOUR_SOFTLAYER_API_KEY'
#
# https://sldn.softlayer.com/reference/datatypes/SoftLayer_Container_Product_Order
#
product_order = {
'complexType' => 'SoftLayer_Container_Product_Order',
'quantity' => 1,
'packageId' => 206, # 206 is 'Object Storage' package ID
'useHourlyPricing' => false,
'prices' => [
{ 'id' => 16984 }, # "Object Storage - Pay as you go"
]
}
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Product_Order
#
product_order_service = SoftLayer::Service.new( 'SoftLayer_Product_Order',
:username => api_username,
:api_key => api_key,
)
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Product_Order/verifyOrder
#
begin
result = product_order_service.verifyOrder( product_order )
pp result
puts "The order was verified successfully"
rescue => error_reason
puts "The order could not be verified by the server: #{error_reason}"
exit
end
exit
__END__

注文内容が問題ないことがわかります。
softlayer-api-ruby-client で Object Storage を注文する
では、検証した注文内容を実際に注文してみましょう。
次のプログラムになります。
#!/usr/bin/ruby
require 'softlayer_api'
require 'pp'
#
# fill your SoftLayer API username and API key
#
api_username = ENV['SOFTLAYER_API_USERNAME'] || 'YOUR_SOFTLAYER_API_USERNAME'
api_key = ENV['SOFTLAYER_API_KEY'] || 'YOUR_SOFTLAYER_API_KEY'
#
# https://sldn.softlayer.com/reference/datatypes/SoftLayer_Container_Product_Order
#
product_order = {
'complexType' => 'SoftLayer_Container_Product_Order',
'quantity' => 1,
'packageId' => 206, # 206 is 'Object Storage' package ID
'useHourlyPricing' => false,
'prices' => [
{ 'id' => 16984 }, # "Object Storage - Pay as you go"
]
}
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Product_Order
#
product_order_service = SoftLayer::Service.new( 'SoftLayer_Product_Order',
:username => api_username,
:api_key => api_key,
)
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Product_Order/verifyOrder
#
begin
result = product_order_service.verifyOrder( product_order )
puts "The order was verified successfully"
rescue => error_reason
puts "The order could not be verified by the server: #{error_reason}"
exit
end
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Product_Order/placeOrder

begin

puts "The order was placed successfully"
pp result
rescue => error_reason
puts "The order could not be placed by the server: #{error_reason}"
exit
end
exit
__END__
これを実行すると次の結果が得られます。

このように Object Storage が注文できました。
softlayer-api-ruby-client で Object Storage を確認する
ポータルの Object Storage から確認することもできますが、softlayer-api-ruby-client からも確認してみましょう。
SoftLayer_Account サービスの SoftLayer_Account::getHubNetworkStorage で Object Storage の一覧が確認できます。
#!/usr/bin/ruby
require 'softlayer_api'
require 'pp'
#
# fill your SoftLayer API username and API key
#
api_username = ENV['SOFTLAYER_API_USERNAME'] || 'YOUR_SOFTLAYER_API_USERNAME'
api_key = ENV['SOFTLAYER_API_KEY'] || 'YOUR_SOFTLAYER_API_KEY'
#
# http://sldn.softlayer.com/reference/services/SoftLayer_Account
#
account_service = SoftLayer::Service.new( 'SoftLayer_Account',
:username => api_username,
:api_key => api_key,
)
#
# result
#
pp account_service.getHubNetworkStorage
__END__
このプログラムを実行すると、次のように先に注文した Object Storage の内容が取得できます。

Object Storage を Ruby プログラムから利用する
注文した Object Storage はさまざまなプログラミング言語から利用できますが、ここでは Ruby プログラムから利用する softlayer-object-storage-ruby を用いてみましょう。
2014年6月25日現在、softlayer-object-storage-ruby は正式にリリースされておらず、またバグが含まれているので、次の手順で SoftLayer 公式 ではなく フォーク から取得してインストールしてください。

では、softlayer-object-storage-ruby を利用したサンプルプログラムを作成してみます。
動作の流れとしては、次のようにします。
- コンテナの一覧を表示する (SoftLayer/ObjectStorage/Connection:containers)
- コンテナを追加する (SoftLayer/ObjectStorage/Connection#create_container)
- 再度、コンテナの一覧を表示する。
- オブジェクト(疑似ディレクトリ: Pseudo-hierarchical folders and directories) を作成する (SoftLayer/ObjectStorage/Container#create_object, SoftLayer/ObjectStorage/StorageObject#write)
- オブジェクトの一覧を表示する (SoftLayer/ObjectStorage/Container#objects)
- 指定したファイルをオブジェクトとしてアップロードする (SoftLayer/ObjectStorage/StorageObject#load_from_filename)
- 再度、オブジェクトの一覧を表示する。
- アップロードしたファイルをダウンロードする (SoftLayer/ObjectStorage/StorageObject#save_to_filename)
- アップロードしたファイルとダウンロードしたファイルを比較する (fileutils/FileUtils#cmp)
なお、対象となる Object Storage のユーザ名を指定しておく必要があります。ここでは username で示されている SLOSxxxx78-4 がそれに当たります。
また、プログラムに引数として与える適当なファイルを準備してください。
#!/usr/bin/ruby

pp obj_str_dl
#
# compare file
#
print 'compare file: '
pp FileUtils.cmp( file, '/tmp/dl_' + File.basename( file ) )
exit
__END__
このプログラムを実行すると、次のような結果となります。
list container: ["Container"]
create container: MyContainer
create container: ["Container", "MyContainer"]
create object: tmp
list objects: ["tmp"]
list objects: ["tmp"]
list objects: ["tmp"]
upload file: tmp/up_cl-sl.png
list objects: ["tmp", "tmp/up_cl-sl.png"]
list objects: ["tmp"]
list objects: ["tmp", "tmp/up_cl-sl.png"]
download file: tmp/up_cl-sl.png
compare file: true
Object Storage にコンテナやオブジェクトを作成し、ファイルをアップロード、ダウンロード、そして比較して問題のないことが確認できました。
まとめ
Object Storage は大量の非構造化データを安価に堅牢に扱うことのできるストレージです。
是非活用してみてください。
なお、先に述べた通り、softlayer-object-storage-ruby は2014年6月25日現在正式にリリースされておらず、本記事では検証できない項目も多数ありましたが、引き続き修正を働きかけていきます。
