I love this idea, and because docker feels so much lighter than vagrant, and doesn't require virtualbox to be installed and updated (like vagrant did on windows when I used it). However on mac and windows, using docker means you're running in a VM. I wonder if there's any plan on implementing the APIs that would allow docker server to run in WSL, thus abrogating the need for a VM? Edit: theres no evidence of any motion, but here's a uservoice for namespace, cgroups,etc support in WSL: https://wpdev.uservoice.com/forums/266908-command-prompt-console-windows-subsystem-for-l/suggestions/31120939-support-kernel-namespaces-and-cgroups-for-docker https://wpdev.uservoice.com/forums/266908-command-prompt-con... Edit2: Actually it looks like docker support is being worked on: https://github.com/Microsoft/WSL/issues/2291#issuecomment-438388987 https://github.com/Microsoft/WSL/issues/2291#issuecomment-43...

Thank you. Nice to hear - I will keep hacking away at it

Docker for Mac and Docker for Windows do use a VM, but it’s a single VM for the entire host system, not one VM per container. So the overhead is very reasonable.

  My big issue with Docker for Windows is that it prevents VMWare Workstation from running, as it uses Hyper-V. You can have one or the other, but not both.

    +1 - Super annoying. I've never seen a good explanation of why hypervisors can't co-exist on Windows. I'm sure there's a technical reason but if anyone has any articles that explain this I'm very interested!

      they also cant coexists on linux, you know... Its a hardware limitation. You have to give the hardware component responsible for the 64bit virtualization to either hypervisor, wherever that is vbox, kvm or hyperv unless you're fine with 32bit. In that case you can use any system you want at the same time (also on windows)
