Testcontainers#exposeHostPorts does not work together with reuse

[jakobbraun]

When reusing a container together with Testcontainers#exposeHostPorts the second container startup fails with an exception.

Example (using testconatienrs 1.15.0):

package com.example;

import org.junit.jupiter.api.Test;
import org.testcontainers.containers.GenericContainer;
import org.testcontainers.junit.jupiter.Testcontainers;

@Testcontainers
public class MyTest {

    @Test
    void test() {
        org.testcontainers.Testcontainers.exposeHostPorts(8000);
        final GenericContainer container = new GenericContainer<>("alpine").withReuse(true).withCommand("top");
        container.start();

        final GenericContainer container2 = new GenericContainer<>("alpine").withReuse(true).withCommand("top");
        container2.start();
    }
}

Result:

org.testcontainers.containers.ContainerLaunchException: Container startup failed
Caused by: org.rnorth.ducttape.RetryCountExceededException: Retry limit hit with exception
Caused by: org.testcontainers.containers.ContainerLaunchException: Could not create/start container
Caused by: com.github.dockerjava.api.exception.DockerException: Status 403: {"message":"endpoint with name objective_benz already exists in network bridge"}

Expected Result:

• no exception is thrown
• Host is reachable from inside the container under host.testcontainers.internal:8000

when you have withReuse turned on, and new container gets started on retry - TC still waits for the previous port, despite new container started on a new one.
