Linux Containers - LXD - ニュース

6th of August 2021

はじめに ¶

LXD チームは LXD 4.17 のリリースをお知らせできることにとてもワクワクしています!

このリリースはいくつか主要な機能が含まれています。それは、再構築したディザスターリカバリーメカニズム、クラスターメンバーの待避を実行できる機能です。それに加えて、lxc info が少し見直されました。そして、event と resource API 関連で多数の細かい改良が加えられています。

LXD 4.17 は私たちの新しい仕様書プロセスを通った主要機能を持った初めてのリリースです。関連する仕様書は次の URL にリンクされており、仕様書の全リストを見ることができます: https://discuss.linuxcontainers.org/c/specifications/18

Enjoy!

新機能とハイライト ¶

`lxd import` の新コマンド `lxd recover` への置き換え ¶

長い間、LXD のディザスターリカバリーストーリーは lxd import コマンドに基づいていました。これは、指定したインスタンスをファイルシステム上の期待されるパスで探し、インスタンスストレージに含まれる backup.yaml を読み、その情報に基づいてインスタンスのデータベースのエントリーを再作成します。

この機能は確かに動作しており、何らかの理由で LXD データベースを失った場合にうまく使われてきていました。しかし、この機能はインスタンスに限定されており、LXD で読み込んだりインポートできるように、インスタンスのファイルシステムを適切な場所に配置するために、かなりの手作業が必要でした。

このコマンドは新たに lxd recover コマンドにすべて置き換えられました。このコマンドは lxd init と同様な対話型のコマンドです。インスタンスとカスタムストレージボリュームの両方がインポートでき、既存のストレージプールと失われたストレージプールの両方をサポートしています。

lxd recover では、まずは既存のストレージプールの概要を表示します。それから、失われたストレージプールを追加できます。次にすべてのストレージプールをスキャンして、不足しているインスタンスやカスタムストレージボリュームを探します。スキャンの一部として、不足している依存関係（プロファイル、プロジェクト、ネットワークなど）も報告します。ユーザーはこれらの不足している依存関係を追加する機会を得た後、インポートを進められます。

クラスターメンバーの待避（evecuation） ¶

プロダクション環境のクラスターメンバーはすべて、いつかはメンテナンスが必要になるでしょう。
定例のシステム更新やハードウェアのメンテナンスなど、管理者がシステム上のすべてのインスタンスを停止させるか移動させる必要がある場合があります。

それが、新しいクラスター待避 API と CLI で簡単にできるようになりました。
管理者は単に lxc cluster evacuate lxd01 と実行するだけで、lxd01 上のすべてのインスタンスを他のクラスターメンバーにマイグレーションしたり、停止させたりできるようになりました。

デフォルトの動作は、対象となるインスタンスがローカルリソースを使用していて、マイグレーションができない場合をのぞいて、マイグレーションしようとします。マイグレーションできない場合は、代わりに停止させます。この動作は cluster.evacuate 設定オプションで制御できます。

システムが完全にオンラインに戻った場合、lxc cluster restore lxd01 を実行すると、移動したインスタンスはすべて戻り、すべてのインスタンスが復帰します。

この機能に関連する仕様書: https://discuss.linuxcontainers.org/t/lxd-cluster-member-evacuation/11330

`lxc info` 出力の見直し ¶

lxc info の出力がかなり見直されました。もっとも目に付く変更はスナップショットやバックアップのリストを表示する表になるでしょう。
それに加えて、ネットワーク情報と統計情報を整理し、拡張しました。また、メモリーとディスク情報に IEC 単位系を使うようになりました。

この結果、次のようになります:

ライフサイクルイベント中のリクエスト元アドレス ¶

現在ライフサイクルイベントの一部として記録されているプロトコルとユーザー名に加えて、リクエスト元の IP アドレスも記録されるようになりました。

location: abydos
metadata:
  action: instance-restarted
  requestor:
    address: '[2602:fc62:b:1000:ea29:c5e9:8544:e32d]:36276'

リソース API 内の USB GPU サポート ¶

LXD のリソース API（lxc info --resources）が、DisplayLink チップベースの GPU と同様に、適切に USB GPU を表示するようになりました。

gpu:
  cards:
  - driver: evdi
    driver_version: 5.11.0-7620-generic
    drm:
      id: 0
      card_name: card0
      card_device: "226:0"
      control_name: controlD64
      control_device: "226:0"
    numa_node: 0
    usb_address: "2:6"

`lxc monitor` を使った全プロジェクトのモニタリング ¶

新たに lxc monitor に --all-projects オプションが追加されました。これは名前の通り現在のプロジェクトだけでなく、すべてのプロジェクトのイベントを監視できます。

`lxc monitor` のフォーマットオプション ¶

さらに lxc monitor に、--format オプションが追加されました。このオプションには 3 種類の出力が指定できます:

pretty （--pretty と同じ）
yaml （デフォルトと同じ動作）
json
