Dockerfile testcontainers无法连接Ryuk

Question

我尝试dockerize我的java spring应用程序。

在my build.gradle

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());
}
}

}

Dockerfile:

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"]

然后从终端I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:

2010-10-24 09:12:25.781 WARN[，，] 1—[container -ryuk]testcontainers.utility. resourcereaper:无法连接到Ryuk172.17.0.1:50582

我做错了什么?不幸的是，经过两天的努力，我已经没有主意了。

btw:我禁用了使用gRPC FUSE从Docker共享文件，没有帮助。我用macos。

Answer 1

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 ...

Answer 2

根据Testcontainers文档，WORKDIR应该具有与OS启动点相同的绝对路径。尝试添加这些配置

docker run -v /var/run/docker.sock:/var/run/docker.sock 
-p 8080:8080 
-v $PWD:$PWD 
-w $PWD 
myapplication:latest
