Failed to connect to PostgreSQLContainer: java.io.EOFException

Tyulpan Tyulpan :

Creating my container as:

public static PostgreSQLContainer<?> container = new PostgreSQLContainer<>("postgres:latest");

static {
    container.start();

    System.setProperty("driver-class-name", container.getDriverClassName());
    System.setProperty("spring.datasource.url", container.getJdbcUrl());
    System.setProperty("spring.datasource.username", container.getUsername());
    System.setProperty("spring.datasource.password", container.getPassword());
}

I'm trying to enter debug mode after start and check connection, however I keep getting

[08001] The connection attempt failed. java.io.EOFException.

Full exception trace:

org.postgresql.util.PSQLException: The connection attempt failed.

So it's pretty obvious that my application cannot connect to it as well.

Any suggestions?

Answering my own question, the problem was container was not able to receive connections, I'm not sure actually why, coz config looks fine for me, but working solution is to initialize container as https://www.testcontainers.org/modules/databases/#database-containers-launched-via-jdbc-url-scheme

So here is example of working solution for me, hope it can help to somebody:

@ExtendWith(SpringExtension.class)
@ActiveProfiles("test")
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
  "spring.datasource.url=jdbc:tc:postgresql:12.2:///test?TC_INITSCRIPT=init.sql",
  "spring.datasource.driver-class-name=org.testcontainers.jdbc.ContainerDatabaseDriver"
})
abstract class AbstractIntegrationTestCase {

  public static GenericContainer<?> container = new PostgreSQLContainer<>("postgres:12.2");

  static {
    container.start();
  }

  @Autowired
  protected TestRestTemplate restTemplate;
}
