当在具有SSL的Azure Kubernetes服务上运行时，我的spring-boot应用程序在tomcat服务器中的NPE启动后失败。

首先，什么工作成功：我有一个使用Spring Initializr创建的最小的Spring-boot应用程序：

• 摇篮项目
• Java 11
• Spring Boot 2.1.8
• 唯一的依赖：Spring Web

我想将其与蔚蓝云上的kubernetes集群一起使用。为此，我有一个Azure
Kubernetes服务（AKS）。我使用臂架构建docker镜像。到目前为止，一切正常。我可以将docker映像部署到azure
docker注册表，启动kubernetes集群（具有1个节点），并在调用“ http：// public-ip ：8443 / hello” 后得到“
hello world ”。我使用端口8443，但使用正常的http来确保此端口不是我的问题的根源。

我希望我的应用程序支持HTTPS，因此我使用keytool制作了一个自签名证书。这在localhost上工作正常。它也可以在本地主机上运行的minikube内部运行。但是，当我在AKS上使用该docker映像时，我的应用程序启动后会失败几秒钟。

我激活了

logging.level.org.apache.tomcat=DEBUG
logging.level.org.apache.catalina=DEBUG

在我的application.properties中。我的应用程序的输出是：

谁能给我一个提示我可能是什么问题？谢谢！
