2.1.0 requires minimum docker version?

Question

I'm trying to evaluate Selenium-Jupiter, but get different problems, behavior depending on what version I use.

I'm using gradle 4.6 and

> docker version | grep API
API version:     1.24
API version:     1.24

When using io.github.bonigarcia:selenium-jupiter:2.1.0

gradle clean test --info
...

I assume some config is needed of the interaction between Selenium-Jupiter and Selenoid, like DOCKER_API_VERSION as described here http://aerokube.com/selenoid/latest/#_recommended_docker_settings but I don't know of where to do this config from Selenium-Jupiter side of things.

I realize that this is a rather vage shout for help but hope that someone at least can give me some hint och pointer on how to solve this. I really like the idea about using Docker for this kind of virtualization and I think our GUI tests really could benefit from a solution like this.

You can change the version of the Docker API used by Selenium-Jupiter as follows:

import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.RegisterExtension;
import org.openqa.selenium.WebDriver;

import io.github.bonigarcia.seljup.SeleniumExtension;

public class MyTest {

    @RegisterExtension
    static SeleniumExtension seleniumExtension = new SeleniumExtension();

    @BeforeAll
    static void setup() {
        seleniumExtension.getConfig().setDockerApiVersion("API-version"); // 1.35 by default
    }

    @Test
    void test(WebDriver driver) {
        // your test
    }

}

I would use the latest version of Selenium-Jupiter, 3.1.0 at the time of this writing.
