Always post your code so people can see the relevance of the errors you're getting. However, as a newbie, I'm still going to give it a shot.

org.openqa.selenium.remote.UnreachableBrowserException

Your RemoteWebDriver cannot connect to the remote web driver at the specified URL.

java.net.UnknownHostException: No such host is known (selenium-node-chrome)

This looks like you're using a Docker container name for the hostname of the location of your remote webdriver.

This is what it might look like:

URL driverLocation = new URL("http://remote.webdriver.lives.here:4444/wd/hub");

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
// more options

driver = new RemoteWebDriver(driverLocation, options);
