はじめに ¶

LXD チームは LXD 5.5 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!

このリリースでは、LXD でのオブジェクトストレージのサポート開始を含む、非常にエキサイティングな機能が追加されています。また、小さいながらも歓迎すべき機能追加や修正も行われています。

Enjoy!

新機能とハイライト ¶

（Ceph 上の）ストレージバケット ¶

LXD がオブジェクトストレージサポートをゲットしました!

これはストレージバケットというまったく新しい概念と、専用のコマンド（lxc storage bucket）と API を追加することで実現しています。

この機能で LXD ユーザーは新たにストレージバケットを作成し、サイズの制限を割り当て、そのバケットへのアクセスキーを管理できます。バケットには S3 API を持った独自の URL があります。

初期実装では、S3 API を提供する rados ゲートウェイを持つ Ceph の使用に限定されています。LXD 5.6 では minio を使って、他の全てのストレージドライバーにこの機能を拡張する予定です。

stgraber@dakara:~$ lxc storage create remote-object cephobject cephobject.radosgsw.endpoint=http://athos.hosts.mtl.stgraber.net:7480
Storage pool remote-object created

stgraber@dakara:~$ lxc storage bucket create remote-object foo

stgraber@dakara:~$ lxc storage bucket key create remote-object foo admin --role admin

上記のように、標準的な S3 クライアントを使って新しいバケットの作成と利用を見ることができます。

インスタンスの使用可能状態 ¶

LXD ユーザーが直面する共通の問題に、インスタンスがいつ使用可能になるかを知りたいという問題がありました。
この問題は "ready" の定義がかなり状況固有になるため、LXD だけで解決できる問題ではありません。しかし、LXD にできることは、いつ使用可能になったかを教え、それを API を通して公開することです。

この方法は、ゲスト API（/dev/lxd）を通して動作します:

stgraber@dakara:~$ lxc list u1
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+
| NAME |  STATE  |         IPV4          |                   IPV6                    |   TYPE    | SNAPSHOTS |
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+
| u1   | RUNNING | 172.17.250.107 (eth0) | 2602:fc62:b:250:216:3eff:feb9:e5bd (eth0) | CONTAINER | 0         |
+------+---------+-----------------------+-------------------------------------------+-----------+-----------+

stgraber@dakara:~$ lxc exec u1 bash
root@u1:~# curl --unix-socket /dev/lxd/sock lxd/1.0
{"state":"Started","api_version":"1.0","instance_type":"container","location":"none"}
root@u1:~# curl --unix-socket /dev/lxd/sock lxd/1.0 -X PATCH -d '{"state": "Ready"}'
root@u1:~# exit

stgraber@dakara:~$ lxc list u1
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+
| NAME | STATE |         IPV4          |                   IPV6                    |   TYPE    | SNAPSHOTS |
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+
| u1   | READY | 172.17.250.107 (eth0) | 2602:fc62:b:250:216:3eff:feb9:e5bd (eth0) | CONTAINER | 0         |
+------+-------+-----------------------+-------------------------------------------+-----------+-----------+

devlxd API が無効化されていない限り、この機能はコンテナと仮想マシンの両方で動作します。

BGP ホールドタイムの設定 ¶

新たに bgp.peers.NAME.holdtime という設定キーを導入しました。
これにより、ピアに特定の BGP ホールドタイムの値を設定できます。通常のデフォルト値である 180 秒よりずっと小さな値に減らせます。

全プロジェクトのストレージボリューム情報の取得 ¶

ここしばらくのインスタンス API と同様に、URL で ?all-projects=true というキーワードを使って、プロジェクトをまたがるボリューム情報を取得できるようになりました。

stgraber@dakara:~$ lxc query /1.0/storage-pools/default/volumes?all-projects=true
[
    "/1.0/storage-pools/default/volumes/container/bgp-test",
    "/1.0/storage-pools/default/volumes/container/centos3",
    "/1.0/storage-pools/default/volumes/container/centos4",
    "/1.0/storage-pools/default/volumes/container/charmcraft-lxd-1779348-0-0-amd64?project=charmcraft",
    "/1.0/storage-pools/default/volumes/container/lxd-build",
    "/1.0/storage-pools/default/volumes/container/snapcraft-lxd",
    "/1.0/storage-pools/default/volumes/container/snapcraft-microceph-1142335?project=snapcraft",
    "/1.0/storage-pools/default/volumes/container/speedtest",
    "/1.0/storage-pools/default/volumes/container/u1",
    "/1.0/storage-pools/default/volumes/custom/backups",
    "/1.0/storage-pools/default/volumes/custom/images",
    "/1.0/storage-pools/default/volumes/virtual-machine/v1",
    "/1.0/storage-pools/default/volumes/virtual-machine/v2",
    "/1.0/storage-pools/default/volumes/virtual-machine/win11"
]

メトリクスの OOM kill カウンター ¶

新しいメトリクス API エントリーを追加しました。カーネルの Out Of Memory killer が発生した回数を監視します。

stgraber@dakara:~$ lxc config set u1 limits.memory=64MiB
stgraber@dakara:~$ lxc query /1.0/metrics | grep lxd_memory_OOM_kills_total
# HELP lxd_memory_OOM_kills_total The number of out of memory kills.
# TYPE lxd_memory_OOM_kills_total counter
lxd_memory_OOM_kills_total{name="u1",project="default",type="container"} 0

stgraber@dakara:~$ lxc exec u1 -- apt update
Hit:1 http://archive.ubuntu.com/ubuntu focal InRelease
Hit:2 http://security.ubuntu.com/ubuntu focal-security InRelease
Hit:3 http://archive.ubuntu.com/ubuntu focal-updates InRelease
stgraber@dakara:~$ ts... 56% Killed

stgraber@dakara:~$ lxc query /1.0/metrics | grep lxd_memory_OOM_kills_total
# HELP lxd_memory_OOM_kills_total The number of out of memory kills.
# TYPE lxd_memory_OOM_kills_total counter
lxd_memory_OOM_kills_total{name="u1",project="default",type="container"} 1

データベースの最適化 ¶

最後に、新機能ではありませんが、このリリースの重要な注目点です。
LXD が実行するデータベースリクエストの回数を減らし、これらのリクエストを全体的に最適化するために、多くの作業を行いました。

これにより、全体的にパフォーマンスが向上しました。そして、一部の大規模なクラスターユーザーで発生していたような多数のタイムアウトが回避できるはずです。
