用于测试的Elasticsearch和Testcontainers

Question

我尝试使用elasticsearch容器编写测试.我用https://www.testcontainers.org/库运行它.那是我的配置:

@ClassRule
public static GenericContainer elasticContainer =
        new GenericContainer("docker.elastic.co/elasticsearch/elasticsearch:5.3.0")
                .withExposedPorts(9300, 9200)
                .withEnv("xpack.security.enabled", "false")
                .withEnv("transport.host", "127.0.0.1")
                .withEnv("http.host", "0.0.0.0");

我有一个例外:

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{9fuJUZYWS6O6IgLGOgJDaA}{localhost}{127.0.0.1:32792}]

我重新配置了我的端口进行测试,并且可以使用9200端口(在testcontainers映射的端口上) - 我通过curl检查了它.但9300不是.

有谁知道如何解决运输主机问题？

问题在于弹性搜索容器 - 而不是testcontainers lib.

我在这里找到了解决方案 https://github.com/olivere/elastic/issues/57#issuecomment-88697714

传输客户端无法解析容器中的ElasticSearch节点.

最终代码是:

@ClassRule
public static GenericContainer elasticContainer =
        new FixedHostPortGenericContainer("docker.elastic.co/elasticsearch/elasticsearch:5.3.0")
                .withFixedExposedPort(9200, 9200)
                .withFixedExposedPort(9300, 9300)
                .waitingFor(Wait.forHttp("/")) // Wait until elastic start
                .withEnv("xpack.security.enabled", "false")
                .withEnv("network.host", "_site_")
                .withEnv("network.publish_host", "_local_");

此外,如果你想在docker中启动ElasticSearch并使用9300(传输端口)运行:

docker run  -p 9300:9300 -p 9200:9200 -e "xpack.security.enabled=false"  -e "network.host=_site_" -e "network.publish_host=_local_"  docker.elastic.co/elasticsearch/elasticsearch:5.3.0

对于现在提出这个问题的任何人,请注意,从Testcontainers 1.10.1开始,我们将Elasticsearch作为Testcontainers库中的官方模块.你应该发现这比使用'滚动你自己'要容易得多GenericContainer!
