Dockerfile testcontainers Can not connect to Ryuk

I try to dockerize my java spring application.

In my build.gradle

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

In my test file:

@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"]

then from terminal I run:

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

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

And after all I see an error:

2021-10-24 09:12:25.781 WARN [,,] 1 --- [containers-ryuk] o.testcontainers.utility.ResourceReaper : Can not connect to Ryuk at 172.17.0.1:50582

What am I doing wrong? Unfortunately, after two days of struggling, I have run out of ideas.

btw: I disabled Use gRPC FUSE for file sharing from Docker and didn't help. I use macos.

add -e TESTCONTAINERS_HOST_OVERRIDE=docker.for.mac.host.internal after your run command

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

According to Testcontainers docs the WORKDIR should have the same absolute path as the OS launching point. Try to add these configs

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