spring-boot ポッドを構成し、livenessおよびreadinessプローブを構成しました。ポッドを起動すると、describeコマンドは以下の出力を表示しています。

ポッドの定義は以下のようなものです

          livenessProbe:

              path: /actuator/health/liveness

      restartPolicy: Always

マニフェストでlivenessandreadinessプローブを無効にして Pod に入ると、andエンドポイントを呼び出したときに有効な応答が得られます。Kubernetes でエンドポイントを呼び出すと、ポッドが再起動して失敗するのはなぜですか? どこが間違っていますか?replica-setexechttp://localhost:8222/actuator/health/livenesshttp://localhost:8222/actuator/health/readinessreadinessliveness

更新セクション を削除するresourceと、ポッドは実行されますが、resourceパラメーターを追加するprobesと失敗します。
