我创建了一个集成测试，用于从elasticsearch检索数据。
我正在使用testcontainer的默认值，这样我的resthighlevelclient应该可以访问测试容器，但是每次我都得到相同的异常( java.net.ConnecteException: Connection refused )当我试图索引数据时，但是当我在本地运行命令时，docker映像

docker run -d --rm -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e "transport.host=127.0.0.1"  --name elastic docker.elastic.co/elasticsearch/elasticsearch:6.5.4

我的测试正常。
问题出在哪里，因为端口Map是相同的？这个例外的原因是什么？
我的测试：

@ExtendWith(SpringExtension.class)
@Testcontainers
@WebMvcTest
class FlowerResourceTest {

    @Container
    private ElasticsearchContainer esContainer = new ElasticsearchContainer("docker.elastic.co/elasticsearch/elasticsearch:6.5.4");

    @Autowired
    private ElasticsearchConfiguration esConfig;

    @Autowired
    private FlowerService flowerService;

    private RestHighLevelClient client;

    @Test
    void test() throws IOException, InterruptedException {
        client = esConfig.client();

        var jsonFlower = "{\n" +
                "    \"name\": \"XXX\",\n" +
                "  \"color\" : \"red\"\n" +
                "}";
        IndexRequest indexRequest = new IndexRequest("flowers", "doc", "1")
                .source(jsonFlower, XContentType.JSON);

        assertTrue(esContainer.isRunning());
        client.index(indexRequest, RequestOptions.DEFAULT);

        var flowers = flowerService.findAll();

        assertTrue(flowers.size() > 0);

        DeleteRequest deleteRequest = new DeleteRequest("flowers", "doc", "1");

        client.delete(deleteRequest, RequestOptions.DEFAULT);
    }
}
