我正在学习 Spring Data Elasticsearch 和 Testcontainers。第一步，我尝试使用 Testcontainers 运行 Elasticsearch 的 docker 镜像，但我花了一整天的时间却无法让它工作。
这是测试类主体:
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.testcontainers.containers.GenericContainer;
import org.testcontainers.junit.jupiter.Container;
import org.testcontainers.junit.jupiter.Testcontainers;
import org.testcontainers.utility.DockerImageName;
@Testcontainers
public class TestcontainersTest {
// container {
@Container
public GenericContainer container = new GenericContainer(DockerImageName.parse("elasticsearch:7.6.2"))
.withExposedPorts(9200)
.withCommand("--name=esTest -e \"discovery.type=single-node\"");
// public GenericContainer container = new GenericContainer(DockerImageName.parse("redis:5.0.3-alpine"))
// .withExposedPorts(6379);
@BeforeEach
public void setUp() {
String address = container.getHost();
Integer port = container.getFirstMappedPort();
// Now we have an address and port for Redis, no matter where it is running
// underTest = new RedisBackedCache(address, port);
}
@Test
public void testTest() {
while (true);
}
}
我为 setUp() 和 testTest() 中的每一行设置了断点，但是当我使用 Debug testTest() 运行时，它只是永远不会到达终点线。 (顺便说一句，我正在使用 IntelliJ IDEA)如果我的理解是正确的，它只是在启动 docker 容器时失败了。
另一方面，如果我更改 setUp 之前注释掉的部分，即更改为使用 redis 镜像(如 Testcontainers 官方网页 JUnit 5 Quickstart 中的代码)，一切进展顺利，我可以在断点处停止并检查容器是否正在使用 docker ps 运行:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0db5ae6e1129 redis:5.0.3-alpine "docker-entrypoint.s…" 7 seconds ago Up 6 seconds 0.0.0.0:32817->6379/tcp wizardly_euler
31620f900e18 testcontainers/ryuk:0.3.0 "/app" 8 seconds ago Up 7 seconds 0.0.0.0:32816->8080/tcp testcontainers-ryuk-e84d6102-4e8c-4c80-bfc7-5deb55864526
我尝试深入了解 Elasticsearch 容器尝试后生成的错误消息。它很长，从中我发现以下内容:
18:09:03.133 [ducttape-0] DEBUG org.testcontainers.containers.ExecInContainerPattern - /determined_brown: Running "exec" command: /bin/sh -c true && (cat /proc/net/tcp* | awk '{print $2}' | grep -i ':0*23f0' || nc -vz -w 1 localhost 9200 || /bin/bash -c '</dev/tcp/localhost/9200')

您会看到前 2 行重复了 3 次。它们实际上重复了 3 次以上，从下面错误消息 block 中前两行的时间戳可以看出:

这两行重复了大约 1 分钟，然后超时。我的问题是，为什么？那里发生了什么事？我该如何解决这个问题？
如果有人想尝试一下，这里是 repo 。您可以忽略除 src/test/java/tagbangers/eatsample/TestcontainersTest.java 之外的所有其他文件，这是上面提到的所有代码和错误消息发生的地方。
或者，我在官方Spring Data Elasticsearch repo中发现了这一点，在 CONTRIBUTING.adoc 中据说
... Spring Data Elasticsearch uses Testcontainers to start a local running Elasticsearch instance.
但我找不到在哪里以及如何实现的？
感谢您的帮助!
编辑:
根据所选答案的建议，我更改为使用 ElasticsearchContainer 而不是 GenericContainer 后解决了。谢谢!
最佳答案
尝试改变:
DockerImageName.parse("elasticsearch:7.6.2")
由
DockerImageName.parse("docker.elastic.co/elasticsearch/elasticsearch:7.6.2")
虽然前者应该重定向到后者......
编辑:问题已通过使用 Elasticsearch module 解决。 ？
关于java - 测试容器在等待容器端口打开时超时，使用 Elasticsearch docker 镜像，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/63953500/
