我在Kubernetes集群上运行了Elasticsearch（使用NodePort公开）
helm install --name my-elasticsearch stable/elasticsearch
kubectl get svc
my-elasticsearch-client NodePort 10.123.40.199 <none> 9200:31429/TCP 107m
my-elasticsearch-discovery ClusterIP None <none> 9300/TCP 107m
我正在尝试从在我的IDE中运行的spring boot应用程序远程连接它。
我的Spring Boot application.properties
注意我正在使用K8s主机IP和my-elasticsearch-client NodePort
spring.data.elasticsearch.cluster-name=elasticsearch
spring.data.elasticsearch.cluster-nodes=10.123.45.147:31429
spring.data.elasticsearch.repositories.enabled=true
我还可以在浏览器的http://10.134.39.147:31429/中访问群集节点

问题是我遇到了 org.elasticsearch.client.transport.NoNodeAvailableException：没有配置的节点可用
我可以确定Elasticsearch已启动，因为我可以通过在同一集群上运行的Kibana访问数据。

答案 0 :(得分：1)
我找到了问题。
TransportClient自动配置的Elasticsearch客户端spring-boot-starter-data-elasticsearch已弃用。它由自动配置，并且需要连接到9300“传输” API。但是，这对于内部Kubernetes发现是一项毫无用处的服务，并且无法公开它。
因此，我已切换到较新的RestHighLevelClient：
https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high.html
此外，我需要禁用此management.health.elasticsearch.enabled=false，因为它正试图连接到本地主机上的Elasticsearh？
我只需要确定弹簧数据RestHighLevelClient是否可以使用ElasticsearchRepository
答案 1 :(得分：0)
您可以从springboot服务器ping我的elasticsearch服务器吗？
您可以在浏览器中访问elasticsearch客户端网址吗？
