当我在本地运行应用程序时，应用程序已经启动并运行，但当我在Kubernetes集群中部署相同的应用程序时，我得到错误

误差

Answer 1

您使用的Spring Cloud Kubernetes版本(1.1.10.RELEASE)需要Spring Boot 2.2.x。您使用的是2.0.x。这个旧版本的Spring Boot使用的是不包含org.springframework.core.env.Profiles类的旧版本Spring Framework。它是在Spring Framework 5.1和Spring Boot 2.0中引入的。使用Spring Framework 5.0.x。

你应该更新你的依赖版本以确保它们是兼容的。为了更容易做到这一点，我建议使用spring-cloud-dependenciesbom，如其项目页面所示。
