-  So for a better experience you can connect using any Microsoft Remote Desktop client to the IP of the container, using the username `docker` and by leaving the password empty.

   There is a good RDP client for [Android](https://play.google.com/store/apps/details?id=com.microsoft.rdc.androidx) available from the Play Store and one for [iOS](https://apps.apple.com/nl/app/microsoft-remote-desktop/id714464092?l=en-GB) in the Apple Store. For Linux you can use [FreeRDP](https://www.freerdp.com/) and on Windows just type `mstsc` in the search box.
