Can I use VirtualBox alongside Docker 4 Windows?

Unfortunately, VirtualBox (and other hypervisors like VMWare) cannot run when Hyper-V is enabled on Windows.

Docker Compose relies on Docker Engine for any meaningful work, so make sure you have Docker Engine installed either locally or remote, depending on your setup.

• On desktop systems like Docker for Mac and Windows, Docker Compose is included as part of those desktop installs.
