Spring Boot，Spring 应用程序在尝试连接到 GKE 中的 elasticsearch 时连接被拒绝

Question

我已经按照this教程

的步骤在gke成功部署了elasticsearch

应用我的应用程序的部署描述符时出现问题，在尝试连接到elasticserach时出现以下异常：

应用程序属性如下：

spring.elasticsearch.uris=https://localhost:9200
spring.elasticsearch.connection-timeout=1s
spring.elasticsearch.socket-timeout=1m
spring.elasticsearch.username=elastic
spring.elasticsearch.password=the_password

elasticsearch配置类如下：

import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@EnableElasticsearchRepositories(basePackages = {"my.app.search.repositories"})
public class ElasticSearchConfig {
}

提前感谢您的宝贵时间

我有同样的问题，但是使用 docker compose。你修好了吗？
