minikubeでHelmを勉強してみた
こんにちは。
ご機嫌いかがでしょうか。
"No human labor is no human error" が大好きな吉井 亮です。
前回 は minikube で Kubernetes クラスターを構築しました。
今回は一歩進んで、パッケージマネージャーである Helm を勉強します。パッケージマネージャーは必須でしょう、おそらく。
Helm のインストール
Mac の場合は以下です。
$ brew install helm
wordpress をデプロイしてみます。
# Helm リポジトリの追加
$ helm repo add bitnami https://charts.bitnami.com/bitnami
# Helm Chart
$ helm install happy-panda bitnami/wordpress
# カスタマイズするなら設定値を記載したファイルを作っておき、読み込ませる
$ helm install happy-panda bitnami/wordpress -f values.yaml
# Namespace を指定する場合
$ helm install happy-panda bitnami/wordpress -f values.yaml -n my-wordpress
Service やら Deployment やらなにやらを自分で書かなくても簡単に Wordpress がデプロイできました。これは便利です。
でも、待ってください。宣言的ではないような気がします。Kubernetes を使うなら宣言的にいきたい。
Helmfile
わざとらしい流れでしたね、失礼しました。
当然ながら宣言的に Helm を使う方法があります。それが Helmfile です。
サクッとインストールします。
$ brew install helmfile
helmfile.yaml を作っておいて、そのディレクトリで helmfile sync または helmfile apply を実行します。
ファイルの書式は こちら を参照ください。
Helmfile でデモ環境を構築
Helmfile の書式を覚えながら、デモ環境を構築してみます。
OpenTelemetry Demo と同じアーキテクチャを構築します。
これ自体は一発で構築できる手順が用意されていますが、勉強のためゼロから Helmfile を書きます。
以下の4つのコンポーネントを構築します。
- デモショッピングサイト
- Otel-collector
- Prometheus
- Grafana
作業ディレクトリはこのような形にしています。helmfile.yaml と values.yaml はセットにしています。
.
├── demo
│ └── opentelemetry-demo.yaml
├── grafana
│ ├── helmfile.yaml
│ └── values.yaml
├── otel-collector
│ ├── helmfile.yaml
│ └── values.yaml
└── prometheus
├── helmfile.yaml
└── values.yaml
Grafana
まずは Grafana から。
helmfile.yaml はリポジトリの指定とリリースの指定が基本になりそうです。helm コマンドの引数に渡していた値を宣言してします。
これが欲しかったという感じです。
grafana/helmfile.yaml
repositories:
- name: grafana
url: https://grafana.github.io/helm-charts
releases:
- name: grafana
namespace: my-grafana
chart: grafana/grafana
version: 7.2.3
values:
- values.yaml
values.yaml を一から書くのは大変なので、helm コマンドで出力したものをファイルに保存します。
$ helm show values grafana/grafana > values.yaml
values.yaml を自分の環境に合わせて修正します。長いので変更箇所だけ抜粋します。
minikube のデフォルトストレージクラスである standard を指定しています。
adminPassword は難しいパスワードにしておきましょう。
grafana/values.yaml
persistence:
enabled: true
storageClassName: standard
adminPassword: admin
datasources:
datasources.yaml:
apiVersion: 1
datasources:
- name: Prometheus
type: prometheus
url: http://prometheus-server.my-prometheus.svc.cluster.local/
isDefault: true
helmfile と values.yaml ができたら helmfile sync でデプロイします。
$ helmfile sync
デプロイされていることを確認します。
$ k get pod,deploy,svc -n my-grafana
NAME READY STATUS RESTARTS AGE
pod/grafana-c4ffdb5c-bd6zq 1/1 Running 0 45s
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/grafana 1/1 1 1 45s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/grafana ClusterIP 10.108.66.12 <none> 80/TCP 45s
Prometheus
次は Prometheus です。
手順は Grafana と同じです。サクサクいきましょう。
prometheus/helmfile.yaml
repositories:
- name: prometheus-community
url: https://prometheus-community.github.io/helm-charts
releases:
- name: prometheus
namespace: my-prometheus
chart: prometheus-community/prometheus
version: 25.9.0
values:
- values.yaml
values.yaml を作ります。
$ helm show values prometheus-community/prometheus > values.yaml
自分の環境に合わせて修正します。
prometheus/values.yaml
server:
persistentVolume:
storageClass: "standard"
serverFiles:
prometheus.yml:
scrape_configs:
- job_name: 'otel-collector'
scrape_interval: 10s
static_configs:
- targets:
- otel-collector-opentelemetry-collector.my-otel.svc.cluster.local:8888
デプロイと確認です。
$ helmfile sync
$ k get pod,deploy,svc -n my-prometheus
NAME READY STATUS RESTARTS AGE
pod/prometheus-alertmanager-0 1/1 Running 0 18h
pod/prometheus-kube-state-metrics-745b475957-9sgf8 1/1 Running 0 18h
pod/prometheus-prometheus-node-exporter-mdk9m 1/1 Running 0 18h
pod/prometheus-prometheus-pushgateway-6574ff77bb-wzt6b 1/1 Running 0 18h
pod/prometheus-server-85b7d5fd59-cdqt9 2/2 Running 0 18h
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/prometheus-kube-state-metrics 1/1 1 1 18h
deployment.apps/prometheus-prometheus-pushgateway 1/1 1 1 18h
deployment.apps/prometheus-server 1/1 1 1 18h
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/prometheus-alertmanager ClusterIP 10.97.150.88 <none> 9093/TCP 18h
service/prometheus-alertmanager-headless ClusterIP None <none> 9093/TCP 18h
service/prometheus-kube-state-metrics ClusterIP 10.97.102.166 <none> 8080/TCP 18h
service/prometheus-prometheus-node-exporter ClusterIP 10.105.180.218 <none> 9100/TCP 18h
service/prometheus-prometheus-pushgateway ClusterIP 10.100.221.233 <none> 9091/TCP 18h
service/prometheus-server ClusterIP 10.109.115.227 <none> 80/TCP 18h
どうでもいいことですが、prometheus-server は 9090 ではなく 80番ポートで開くようです。
Otel-collector
Otel-collector もサクサクいきます。
otel-collector/helmfile.yaml
repositories:
- name: open-telemetry
url: https://open-telemetry.github.io/opentelemetry-helm-charts
releases:
- name: otel-collector
namespace: my-otel
chart: open-telemetry/opentelemetry-collector
version: 25.9.0
values:
- values.yaml
values.yaml を作ります。
$ helm show values open-telemetry/opentelemetry-collector > values.yaml
自分の環境に合わせて修正します。

デモショッピングサイト
デモサイトは opentelemetry-demo をそのまま使います。
kubernetes/opentelemetry-demo.yaml からサイトに必要なコンポーネントだけ抜き出して kubernetes create します。

デモサイトをデプロイしたらブラウザで覗いてみます。
買い物はできませんが、適当にカートに入れたり商品をクリックしたりしてみましょう。
$ minikube service opentelemetry-demo-frontend
Grafana でメトリクスを確認
しばらく動かしているとメトリクスが Grafana に表示されるようになります。
ブラウザで Grafana を開いてみましょう。
$ minikube service grafana -n my-grafana
左ペインのメニュ-から Home → Explore を開きます。
メトリクスはなんでもよいのですが kube_pod_start_time を選んでみます。
続いて system_cpu_time_seconds_total を見ます。これは OpenTelemetry が取得しているメトリクスです。
まとめ
Helm と Helmfile を勉強してみました。かなり宣言的な人間になりました。
Helm Charts は便利な半面、パラメータ全てを理解したうえで使いこなさないとならないと感じました。
