如何为 Azure 托管服务（无端口）指定 elasticsearch spring 引导配置

Question

I created an Azure managed Service for ElasticSearch. Now I want to access it with my Spring Boot Elastic Application.

NOTE: I hide the real URL with the placeholder MyCustomAzureURLwithoutPort.com. In reality it is something like https://myclustername.es.REGION.azure.elastic-cloud.com

My ElasticConfig is:

@Configuration
@EnableElasticsearchRepositories(basePackages = "org.elastic.repositories")
@ComponentScan(basePackages = { "org.elastic" })
public class ElasticsearchClientConfig extends AbstractElasticsearchConfiguration {

    @Override
    @Bean
    public RestHighLevelClient elasticsearchClient() {


        final ClientConfiguration clientConfiguration = 
                ClientConfiguration
                .builder()
                .connectedTo("https://MyCustomAzureURLwithoutPort.com")
                .withBasicAuth(user, pw)
                .build();

        return RestClients
                .create(clientConfiguration)
                .rest();
    }

But I keep getting an error like this:

Disconnected from the target VM, address: '127.0.0.1:52567', transport: 'socket'

I also tried the URL with Port 443 ( https://myclustername.es.REGION.azure.elastic-cloud.com:443 ), that's what the Stacktrace is copied from, but this didn't worked either.

Anyone have an Idea? Need the BasicAuth and connect to this URL without Port.

Thanks!

Answer 1

Elastic cloud uses 9243 and 443 . Therefore, try with 9243 .

You can find the reason here: Why does Elastic Cloud provides a specialized port (9243) instead of only using the default one (443)?
