opensearch-testcontainers

A Testcontainers integration for OpenSearch.

Overview

The opensearch-testcontainers delivers idiomatic integration of the OpenSearch Docker containers with Testcontainers test scaffolding, since the out-of-the box support has been ruled out by maintainers for the time being.

Testcontainers and OpenSearch Compatibility

Usage

<dependency>
    <groupId>org.opensearch</groupId>
    <artifactId>opensearch-testcontainers</artifactId>
    <version>2.1.1</version>
    <scope>test</scope>
</dependency>

The opensearch-testcontainers could be used with JUnit 4 or JUnit 5.

JUnit 4 Integration

Follow the JUnit 4 Quickstart to customize the container to your needs.

@Rule
public OpensearchContainer<?> opensearch = new OpensearchContainer<>(DockerImageName.parse("opensearchproject/opensearch:2.11.0"));

JUnit 5 Integration

Follow the JUnit 5 Quickstart to activate @Testcontainers extension and to customize the container to your needs.

@Container
public OpensearchContainer<?> opensearch = new OpensearchContainer<>(DockerImageName.parse("opensearchproject/opensearch:2.11.0"));

Please note that at the moment testcontainers brings in JUnit 4.x dependencies. If it conflicts with your project configuration, please follow linked Github issue for available mitigation strategies.

Usage Examples

By default, OpenSearch Docker containers run with security plugin activated, however OpensearchContainer deactivates it. Use withSecurityEnabled() to enable security, please notice that in this case in order to connect to the running container the HTTPS protocol should be used along with username / password credentials.

import javax.net.ssl.SSLContext;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.conn.ssl.TrustAllStrategy;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.ssl.SSLContextBuilder;
import org.opensearch.client.Request;
import org.opensearch.client.Response;
import org.opensearch.client.RestClient;

private static final DockerImageName OPENSEARCH_IMAGE = DockerImageName.parse("opensearchproject/opensearch:2.11.0");

// Create the Opensearch container.
try (OpensearchContainer<?> container = new OpensearchContainer<>(OPENSEARCH_IMAGE).withSecurityEnabled()) {
    // Start the container. This step might take some time...
    container.start();

    // Do whatever you want with the rest client ...
    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(
        AuthScope.ANY,
        new UsernamePasswordCredentials(container.getUsername(), container.getPassword())
    );

    // Allow self-signed certificates
    final SSLContext sslcontext = SSLContextBuilder.create()
            .loadTrustMaterial(null, new TrustAllStrategy())
            .build();

    try (RestClient client = RestClient
            .builder(HttpHost.create(container.getHttpHostAddress()))
            .setHttpClientConfigCallback(httpClientBuilder -> {
                return httpClientBuilder
                        .setSSLContext(sslcontext)
                        .setDefaultCredentialsProvider(credentialsProvider);
            })
            .build()) {

        final Response response = client.performRequest(new Request("GET", "/_cluster/health"));
        ...
    }
}

When security plugin is not required (not recommended for production), just use OpensearchContainer default constructor.

import org.apache.http.HttpHost;
import org.opensearch.client.Request;
import org.opensearch.client.Response;
import org.opensearch.client.RestClient;

private static final DockerImageName OPENSEARCH_IMAGE = DockerImageName.parse("opensearchproject/opensearch:2.11.0");

// Create the OpenSearch container.
try (OpensearchContainer<?> container = new OpensearchContainer<>(OPENSEARCH_IMAGE)) {
    // Start the container. This step might take some time...
    container.start();

    try (RestClient client = RestClient
            .builder(HttpHost.create(container.getHttpHostAddress()))
            .build()) {

        final Response response = client.performRequest(new Request("GET", "/_cluster/health"));
        ...
    }
}
