LXD 5.4 リリースのお知らせ

25th of July 2022

はじめに

LXD チームは LXD 5.4 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!

今回のリリースは、今後のリリースに含まれるかなりの新機能の始まりになるでしょう。新機能の 1 つは主要な新機能で、今後さらに必要となる機能の基盤となる機能です。

Enjoy!

アップグレード時の注意

vsock API の変更（LXD VM）

両方向の vsock インターフェース（下記参照）の作業の一環で、LXD VM 内部のホストからゲストへの通信での TLS の扱いがかなり壊れていることに気づきました。

サーバーとクライアントの認証はすべて正しく行われていたので、セキュリティの観点では懸念することはありません。特に理由もなく TLS over TLS を行っていたので、意味もなくオーバーヘッドが 2 倍になり、実際に REST/HTTP レイヤーがクライアントについての詳細にアクセスすることを妨げていました。

このリリースでは LXD と VM エージェントの両方をアップデートし、TLS の単一のレイヤーでのみ処理されるようにして、この問題を修正しました。残念ながら、これは後方互換性のある方法で処理できるものではありません…

この結果、LXD 5.4 へのアップグレードを行うと、すべての実行中の仮想マシンとのエージェントの通信が切断されます。これは lxc exec と lxc file に影響します。lxc restart で影響を受けた VM を再起動することで、更新されたバージョンのエージェントで VM を再起動され、この問題が修正されます。

新機能とハイライト

ロードバランサー（OVN）

このリリース最大の新機能です。ネットワークロードバランサーのコンセプトが LXD に導入されます。

既存のネットワークフォワード機能とコンセプトが似ていますが、ロードバランサーは特定のアドレスやポートが複数のターゲットを持て、OVN がソースとデスティネーションアドレスをハッシュ化することでロードバランシングを処理するという点で異なります。

この機能はすべて lxc network load-balancer を通して扱い、現時点では OVN ネットワークに限定されています。

双方向 vsock インターフェース（VM）

LXD の VM では、LXD デーモンは仮想マシン内で動作するエージェント（lxd-agent）と相互に動作します。このような動作によって、lxc exec や lxc file のようなコマンドが、コンテナと同じように動作します。

これは、各 VM が vsock をリスンし、ホストがエージェントに接続することで行われます。
しかし、今回のリリースまで、エージェントからホストに接続する方法はありませんでした。

これはゲストの /dev/lxd API に少し機能が欠けていたという副作用以外にはほぼ問題がありませんでした。しかし、VM に関する機能の将来的に計画している作業で、本当にエージェントが直接ホストに接続する方法が必要でした。

今回のリリースで、LXD 自身が vsock をリスンし、VM が接続できるようになりました。通常のエージェント接続と同様に、この接続はすべて TLS 証明書によって認証されるため、LXD はどの VM と通信しているのか、そしてエージェント（もしくはエージェントキーにアクセスできる何か）が通信していることが確認できます。

ストレージドキュメントの見直し

先日のネットワークのドキュメントに続き、このリリースではストレージのドキュメントを大幅に見直し、再構成しました。

この作業で構造がよりクリアになり、いくつかのコンテンツが追加され、今後数回のリリースで進化を続けるでしょう。

ドキュメント : https://linuxcontainers.org/lxd/docs/latest/explanation/storage/

一貫性のあるストレージボリュームの設定

前述のドキュメント見直しで、ストレージボリュームの設定をストレージボリュームに適用する方法に矛盾があることが判明しました。

具体的には、ストレージプールは volume.XYZ のようなパターンの設定キーを持てます。これらのキーは新しく作成したボリュームに適用され、事実上デフォルト値として機能するはずです。

一貫性がなかったのは、すべてのボリュームキーがサポートされているわけではありませんでした。さらに、サポートされている場合でもキーがボリューム設定に正しくコピーされる場合もあれば、そうでない場合もあり、その場合プールからボリュームにキーが反映される場合もあり、プール構成が変更された時に問題となります。

LXD 5.4 では、すべてのボリュームキーがサポートされ、作成時にプールからボリュームにのみコピーされることですべての一貫性を保っています。

lxd-benchmark のプロジェクトサポート

ビルトインのベンチマークツールである lxd-benchmark （snap を使っている場合は lxd.benchmark）はここ数年間手が加えられていませんでした。最近このツールを引っ張り出してきたところ、プロジェクトのサポートがないことが問題であり、それを追加するのは簡単であることがわかりました。

このため、プロジェクトサポートが追加され、lxd-benchmark で --project NAME 引数を取るようになりました。
