This has everything you need. I also had the same issue on bitbucket. I tried using docker volumes but it didn't. The link below helped me out.

Downloads

Chrome, Edge and Firefox each allow you to set the location of the download directory. When you do this on a remote computer, though, the location is on the remote computer’s local file system. Selenium allows you to enable downloads to get these files onto the client computer. Enable Downloads in the Grid

Regardless of the client, when starting the grid in node or standalone mode, you must add the flag:

--enable-managed-downloads true

Enable Downloads in the Client

The grid uses the se:downloadsEnabled capability to toggle whether to be responsible for managing the browser location. Each of the bindings have a method in the options class to set this.

ChromeOptions options = new ChromeOptions();
options.setEnableDownloads(true);
driver = new RemoteWebDriver(gridUrl, options);

Be aware that Selenium is not waiting for files to finish downloading, so the list is an immediate snapshot of what file names are currently in the directory for the given session.

List<String> files = ((HasDownloads) driver).getDownloadableFiles();

View full example on GitHub Download a File

Selenium looks for the name of the provided file in the list and downloads it to the provided target directory.

((HasDownloads) driver).downloadFile(downloadableFile, targetDirectory);

By default, the download directory is deleted at the end of the applicable session, but you can also delete all files during the session.

((HasDownloads) driver).deleteDownloadableFiles();
