What happened?

I am using testcontainers for my unit test for repository, it passes locally but failed in the jenkins, and it only have one line log trace:

EntityRepositoryTest > initializationError FAILED
  com.github.dockerjava.api.exception.InternalServerErrorException at DefaultInvocationBuilder.java:247

Here are my code, I retaged and pushed postgres:13.2 to company's private jfrog

public class MyRepositoryPostgresqlContainer extends PostgreSQLContainer<MyRepositoryPostgresqlContainer> {

    static private DockerImageName myImage = DockerImageName.parse("comany./postgres:13.2").asCompatibleSubstituteFor("postgres");

    private static MyRepositoryPostgresqlContainer container;

    private MyRepositoryPostgresqlContainer(DockerImageName myImage) {
        super(myImage);
    }

    public static MyRepositoryPostgresqlContainer getInstance() {
        if (container == null) {
            container = new MyRepositoryPostgresqlContainer(myImage)
                    .withDatabaseName("XXX")
                    .withUsername("XXX")
                    .withPassword("XXX);
        }
        return container;
    }
   ...
}

@ContextConfiguration(initializers = {MyTest.Initializer.class})
public class MyTest {

    @ClassRule
    public static PostgreSQLContainer postgreSQLContainer = MyRepositoryPostgresqlContainer.getInstance();

    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());
        }
    }
}

@SpringBootTest
@RunWith(SpringRunner.class)
public class EntityRepositoryTest extends MyTest{
    @Autowired
    private MyRepository repo;
   @Test
    public void test() {
         MyEntity myEntity = MyEntity.builder().
                ....
                .build();
       repo.saveAndFlush(myEntity);
        assertEquals(1, repo.findAll().size());
    }
}

Any suggestion helps, Thanks

Relevant log output

EntityRepositoryTest > initializationError FAILED

### Additional Information

_No response_

Start with EntityRepositoryTest and MyRepositoryPostgresqlContainer, then reproduce the failure on the kube-jenkins environment using the reported Docker and PostgreSQL image setup. Collect the complete Docker and Jenkins logs beyond the single InternalServerErrorException line and compare them with a successful local run. Done means identifying the environment-specific cause and documenting or implementing a verified resolution.
