How to run Docker inside Virtualbox (Ubuntu) and use it on Win10 host

  docker, ubuntu, virtualbox, windows

i´m forced to use Win10 and Docker on my working PC. I like to set up a Virtualbox VM with Ubuntu and install docker on Ubuntu-VM. How can i map Docker from the VM to the Windows Host, run it in Ubuntu VM and use it on Win10 Host?

Thank you
