When trying to reuse a BrowserWebDriverContainer under Linux, starting the container after stopping it once fails with com.github.dockerjava.api.exception.BadRequestException: Status 400: {"message":"Duplicate mount point: /dev/shm"}. Under Windows the following test succeeds - under Linux it does not.
Reproducer:
import org.junit.jupiter.api.Test;
import org.testcontainers.junit.jupiter.Container;
import org.testcontainers.junit.jupiter.Testcontainers;
import org.testcontainers.selenium.BrowserWebDriverContainer;
import org.testcontainers.utility.DockerImageName;
@Testcontainers
public class BuggyTest {
@Container
static final BrowserWebDriverContainer BROWSER_WEB_DRIVER_CONTAINER = new BrowserWebDriverContainer(
DockerImageName.parse("selenium/standalone-chrome:148.0-20260505")
);
@Test
void testContainer() {
BROWSER_WEB_DRIVER_CONTAINER.start();
BROWSER_WEB_DRIVER_CONTAINER.stop();
BROWSER_WEB_DRIVER_CONTAINER.start(); //this fails
BROWSER_WEB_DRIVER_CONTAINER.stop();
}

The problem is most likely located in https://github.com/testcontainers/testcontainers-java/blob/main/modules/selenium/src/main/java/org/testcontainers/containers/BrowserWebDriverContainer.java#L224 that adds the /dev/shm bind again, not checking that the bind has been already added previously.
