こんにちは。
株式会社クラスアクト インフラストラクチャ事業部の大塚です。
現在k8sについて理解を深めるために絶賛色々触っている身分なのですが、JAEGERを触ってみたいと思いHelmベースで環境構築しようと思いました。（なおJAEGER環境は上手く行かなかった模様。）
せっかくHelm環境作ったのでその備忘録をササっと書いておきたいと思います。
クラスタ環境
Helm環境をデプロイした際のクラスタは以下となっております。
Helm環境を作るだけであればこんなスペックはいりません。現在Cephや他の機能を試してみたいと思い、こんな状態になっているだけです汗
| Hostname | IP Address | OS | CPU | Memory | HardDisk 1 | HardDisk 2 |
|---|---|---|---|---|---|---|
| k8s-master | 192.168.2.30 | Ubuntu 22.04.2 LTS | 4sockets 4cores | 48.83GiB | 100G | 10G |
| k8s-worker01 | 192.168.2.31 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 29.30GB | 60G | 50G |
| k8s-worker02 | 192.168.2.32 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 29.30GB | 60G | 50G |
| k8s-worker03 | 192.168.2.33 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 29.30GB | 60G | 50G |
| k8s-ceph01 | 192.168.2.37 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 19.53GiB | 50G | 50G |
| k8s-ceph02 | 192.168.2.38 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 19.53GiB | 50G | 50G |
| k8s-ceph03 | 192.168.2.39 | Ubuntu 22.04.2 LTS | 2sockets 4cores | 19.53GiB | 50G | 50G |
Helmとは
公式サイトより引用します。
docker/kubernetes等により、任意の環境をコマンド1つ（yamlがある前提）でデプロイすることができ、便利になる一方で、数が増えると管理が大変となる。それを解消するためのツールっぽいです。kubernetesはpodやserviceが目立ちますが、ConfigMapやSecret等他にも細々としたものがあります。これらの管理を簡単にしてくれます。
後で出てきますが、内部でBitnamiも使っているっぽく、このBitnamiという文字面を見ると「AWSのLightsailで見たことがあるな～」と個人的に思うのですが、もし同様の方がいれば、小難しく考えずあのイメージでいいと思います。WordpressとかRedmineなどの環境をポチポチするだけで用意してくれるやつ、ってことですね。
Helm は、Kubernetes アプリケーションの管理を支援します。Helm チャートは、最も複雑な Kubernetes アプリケーションの定義、インストール、およびアップグレードを支援します。
構築
以下のサイトを参考にします。
手順通りにHelmをインストールして、インストールできているかを確認するために versionオプションを叩いています。

ここまで対応が済んだら、リポジトリを追加します。
出力された一覧を見てみると、色々環境が用意できそうですね。
以上！！
