予想される行動
Spring Cloud Kubernetes のドキュメントによると、Spring アプリケーションがポッドで実行されていることを検出するために必要なのは、spring-cloud-kubernetes-all依存関係を使用して Spring Cloud Kubernetes をクラスパスに追加することだけです。
これにより、次の 2 つのイベントがトリガーされます。
- 存在する場合、
application-kubernetes.ymlプロファイルがロードされます。 - の Kubernetes 実装は
DiscoveryClientサービス検出に使用され、デフォルトの Eureka の代わりに KubeDNS を利用します。
そしてここ：
実際の動作
次の yaml を使用して Spring Cloud Kubernetes アプリケーションを起動し、NodePort 経由でそのアクチュエーター エンドポイントにアクセスした後、フォルダーに aが存在するにhttp://minikube-ip:port/actuator/envもかかわらず、アクティブなプロファイルが設定されていないことがわかります。application-kubernetes.ymlresources
{
"activeProfiles": [],
...
エンドポイントをさらに調査するとhttp://minikube-ip:port/actuator/info、次のように、Spring アプリケーションがポッド内にあることをまったく認識していないことがわかります。
{
"kubernetes": {
"inside": false
}
}
