Приложение Spring Cloud Kubernetes не определяет, когда оно запущено в модуле

Ожидаемое поведение

Согласно документации Spring Cloud Kubernetes, все, что необходимо приложению Spring для определения, когда оно работает в модуле, - это добавить Spring Cloud Kubernetes в путь к классам с зависимостью spring-cloud-kubernetes-all.

Это вызывает два события:

  1. Если присутствует, загружается профиль application-kubernetes.yml.
  2. Реализация DiscoveryClient в Kubernetes используется для обнаружения служб, используя KubeDNS вместо Eureka по умолчанию.

Эта осведомленность о среде описана здесь: https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#kubernetes-profile-autoconfiguration

и тут:

https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#discoveryclient-for-kubernetes.

Фактическое поведение

После загрузки приложения Spring Cloud Kubernetes с использованием следующего yaml и доступа к конечной точке исполнительного механизма в http://minikube-ip:port/actuator/env через NodePort я вижу, что активных профилей нет, хотя в папке resources существует application-kubernetes.yml:

{
"activeProfiles": [],
...

После дальнейшего исследования конечной точки http://minikube-ip:port/actuator/info я вижу, что приложение Spring вообще не знает, что находится в модуле, о чем свидетельствуют:

{
    "kubernetes": {
        "inside": false
    }
}

Как видите, он все еще пытается подключиться к Eureka.

Очень непонятные документы на тему балансировки нагрузки с помощью Spring Cloud Kubernetes: github. ru / spring-cloud / spring-cloud-kubernetes / issues / 530   -  person alo42    schedule 07.12.2020

ручное применение профиля application-kuberntes.yml также не решает проблему. и применение роли cluster-admin к модулю не решает проблему. конечная точка /actuator/info по-прежнему возвращает {kubernetes { inside: false }}   -  person alo42    schedule 08.12.2020

ПРИМЕЧАНИЕ. Этот репозиторий распознает, что он находится в кластере K8s при первой загрузке, и ведет себя так, как ожидалось: piotrminkowski.com/2020/09/10/   -  person alo42    schedule 09.12.2020

Работает при запуске с skaffold dev --port-forward, но не с k apply -f ./k8s. Очень странный. Будет различать среды skaffold и kubectl, чтобы попытаться найти причину.   -  person alo42    schedule 09.12.2020

Вы уверены, что в application.yml должен быть spring.cloud.kubernetes.enabled=false? Если я правильно понимаю документы, вам нужно оставить значение по умолчанию (true), чтобы он мог выполнить обнаружение и загрузить профиль kubernetes.

Если вы отключите его, он никогда не загрузит ваш application-kubernetes.yaml, поэтому установка для него значения true внутри этого файла не будет иметь никакого эффекта.

Насколько я понимаю, вы можете отключить функции kubernetes (например, spring.cloud.kubernetes.config.enabled=false) в своем основном YAML, но не всю интеграцию k8s, если вы хотите, чтобы автоконфигурация профиля работала.

Вот комбо application.yml, application-kubernetes.yml и build.gradle, которое наконец сработало для меня:
