I have an Elasticsearch cluster in a VPN. How can my Spring Boot application access the cluster securely if it is located on a separate server outside of the VPN and how can I configure it in the Spring boot configuration (application.yml/application.properties)? I also want the application to connect to the cluster i an way so that if i have e.g. 2 Master eligible nodes and one fails, the connection remains intact. I also posted this question on [Stackoverflow.com](https://stackoverflow.com/questions/53020353/how-to-access-elasticsearch-cluster-in-vpn-with-spring-boot) ---

hi @BinaryIsPrimary , how do you connect to elasticsearch form your application? via transport port or via the rest? what version of elasticsearch? ---

you should use RestClient, so when you update your elasticsearch version it isn't necessary to update your client look here, > **[Initialization | Java REST Client \[7.17\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-getting-started-initialization.html)** i use something like this: > @Configuration > public class ElasticsearchConfig { > > @Autowired > private GlobalProperties globalProperties; > > @Bean > public RestHighLevelClient esClient() throws Exception { > ElasticsearchRestClientFactoryBean factory = new ElasticsearchRestClientFactoryBean(); > factory.setEsNodes(new String{globalProperties.getHost()}); > > Properties props = new Properties(); > // props.setProperty("xpack.security.user", "elastic:changeme"); > factory.setProperties(props); > // End: If you are running with x-pack > > factory.afterPropertiesSet(); > return factory.getObject(); > } > } and you should implement destroy method of your bean. and in services: > @Autowired > private RestHighLevelClient restClient; > ... > restClient.index(new IndexRequest("index name","type").source("message body")); > .. ---

Hi nugusbayevkk, I am using ES 6.4.2 and spring-boot-starter-data-elasticsearch 2.1.0.RC1 to connect to my cluster. At the moment, my application is located on the master node server and connects via application.properties with the following settings: spring.data.elasticsearch.cluster-name={cluster name} spring.data.elasticsearch.cluster-nodes=localhost:9300 My repositories are extending the ElasticsearchRepository class. This works like a charm as long as my application is located on a server which runs an elasticsearch node. But ideally, what I want to achieve is locating my application on a separated server and somehow accessing my elasticsearch cluster (running in my mesh vpn) in a safe manner. ---

ok, > took 3 master node for example: > server1 - 192.168.10.1 (master1+data1) > server2 - 192.168.10.2 (master2+data2) > server3 - 192.168.10.3 (master3) on every server you should set `network.bind_host - ["server_ip", "localhost"]` `network.publish_host - "server_ip"` `discovery.zen.ping.unicast.hosts` : ["servers:transport\_port", ...] next, your application placed on server-app, for example. in your configuration you should set all servers. you or your administrators should write rules in firewall(iptables) that allow connect from server-app to your servers where working elasticsearch. or you should use x-pack with security opportunity with enabling tls. ---
