java - Dockerfile testcontainers 无法连接到 Ryuk

Question

我尝试对我的 java spring 应用程序进行 docker 化。

在我的 build.gradle 中

implementation 'org.testcontainers:junit-jupiter'
implementation 'org.testcontainers:postgresql'

在我的测试文件中:

@SpringBootTest
class ApplicationTests {

@ClassRule
public static PostgreSQLContainer postgreSQLContainer = new PostgreSQLContainer("postgres:11.1")
    .withDatabaseName("integration-tests-db")
    .withUsername("sa")
    .withPassword("sa");

static class Initializer
    implements ApplicationContextInitializer<ConfigurableApplicationContext> {
    public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
        TestPropertyValues.of(
            "spring.datasource.url=" + postgreSQLContainer.getJdbcUrl(),
            "spring.datasource.username=" + postgreSQLContainer.getUsername(),
            "spring.datasource.password=" + postgreSQLContainer.getPassword()
        ).applyTo(configurableApplicationContext.getEnvironment());
    }
}

jetty 文件:

FROM adoptopenjdk/openjdk16:jdk-16.0.2_7-alpine-slim
MAINTAINER myapplication

ARG JAR_FILE=build/libs/myapplication-0.0.1-SNAPSHOT.jar

COPY ${JAR_FILE} myapplication-0.0.1-SNAPSHOT.jar
ENTRYPOINT ["java","-jar","/myapplication-0.0.1-SNAPSHOT.jar"]

然后我从终端运行:

docker build --no-cache  --tag=myapplication:latest .

docker run -v /var/run/docker.sock:/var/run/docker.sock -p8080:8080 myapplication:latest

毕竟我看到了一个错误:

我做错了什么？不幸的是，经过两天的挣扎，我已经无计可施了。

顺便说一句:我禁用了使用 gRPC FUSE 从 Docker 共享文件并且没有帮助。我使用 macOS。

在运行命令后添加 -e TESTCONTAINERS_HOST_OVERRIDE=docker.for.mac.host.internal

docker run -e TESTCONTAINERS_HOST_OVERRIDE=docker.for.mac.host.internal ...
