Testcontainers could not find a valid Docker env - spring-boot

Question

Running testcontainers leads to failed initialization.
Config class:
#ActiveProfiles("test")
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
#ContextConfiguration(initializers = {Postgres.Initializer.class})
#SpringBootTest
#Transactional
#Sql("classpath: schema.sql")
public abstract class IntegrationTestConfig {
#Autowired
protected ApplicationContext applicationContext;
#BeforeAll
static void startContainer(){
Postgres.CONTAINER.start();
}
}
Initializer class:
#UtilityClass
public class Postgres {
public static final PostgreSQLContainer CONTAINER = new PostgreSQLContainer("postgres:14.0");
public static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext applicationContext) {
TestPropertyValues.of(
"spring.datasource.url=" + CONTAINER.getJdbcUrl(),
"spring.datasource.username=" + CONTAINER.getUsername(),
"spring.datasource.password=" + CONTAINER.getPassword()
).applyTo(applicationContext);
}
}
}
ommiting simple test classes for brievety, I catch:

I tried to switch tc versions: 1.16.2 \1,1.15.3 . I checked user privileges - I already start docker w/o sudo. I also checked postgres image - both 14.0 inside the docker and tc initializer. What else I could try to solve the problem?

Answer 1

Well, Ive found out that java cant see files located into /var/run, so I remembered that I used flatpack for installation which turns out to be isolated environment for idea . Reinstalled traditionally idea works flawlessly.
